What are /r/Anki's favorite Products & Services?

From 3.5 billion Reddit comments

Just want to say a massive thank you to the community for the vote of confidence! This is near unachievable for an established app.

A better rating entices more people to use the app, which will lead to more people contributing back to the community - both from a development perspective, and means a wider variety of shared decks to choose from.

It truly warms my heart to contribute to this. Thank you!

there's one important piece missing:

Special thanks to /u/David_AnkiDroid for the massive number of contributions to Ankidroid.

You can see his recent code contributions here. And there's the support in the github issues and here, and ...

Well, this is it, folks! The stable release of Anki 2.1 is finally here.

For a list of changes compared to the final release candidate please see here. For previous discussions on 2.1 and the changes it brings please feel free to checkout the beta release threads.

We have a lot of users using it without issue. There's a few known issues, but #5805 (the timezone issue) is the most serious.

I've been working on it on-and-off for the past few months. It requires a massive architectural change (which I'm almost certain won't work out-the-box for certain phones), but it should be in AnkiDroid 2.15.

https://github.com/ankidroid/Anki-Android/issues?q=is%3Aopen+is%3Aissue+label%3A%22V2+Scheduler%22 - list of reported issues.

There's an FAQ entry in the Anki manual:

https://apps.ankiweb.net/docs/manual.html#why-is-the-android-version-free-when-the-iphone-version-isn%E2%80%99t

> ###Why is the Android version free when the iPhone version isn’t? > Working on Anki desktop, AnkiWeb and AnkiMobile is my full time job, and I need some way of paying the bills. Since I make the desktop & web versions available for free, I rely on sales of the iPhone app in order to finance development. > > AnkiDroid is written by a separate group of volunteers. Since they based it on the free desktop version I make available (and rely on AnkiWeb in order to synchronize decks), they decided to make it freely available as well.

this has been discussed many, many times. It's unlikely that you'll quickly get all the good answers. you could search this subreddit and the official forum at anki.tenderapp.com

some ideas:

• I don't like resetting because this wastes time. I would go over it once, rate honestly. Maybe you'll remember some which will save a lot of time Use deck options (like Lapse - New interval 0%") that effectivly reset the card to learning.
• you might wonder about the large intervals: https://apps.ankiweb.net/docs/manual.html#i-haven%E2%80%99t-studied-for-a-while,-and-now-the-next-due-times-are-too-big
• if you don't like these you can remove the bonus on desktop with the add-on MentalPause: No bonus for being late
• I don't care if I finish all of my due reviews on a given day. I only try to make sure to review cards that have very short intervals: If I have an interval of a day and I review a day late that makes a huge difference. If I have an interval of 127 days it makes no difference to review after 129 days. On the desktop there's the add-on "hoochieMama" for this (or the older "Change order of review cards in regular decks")

RTFM: https://apps.ankiweb.net/docs/manual.html#backups

> Each time your collection is closed (when closing Anki, switching profiles, or synchronizing your deck), Anki exports your collection into the backups folder. By default Anki will store up to 30 backups

...

> Anki also logs deleted notes to a text file called deleted.txt in your profile folder. These notes are in a text format that can be read by File>Import, though please note the import feature only supports a single note type at one time, so if you have deleted notes from different note types, you’ll need to split the file into separate files for each note type first.

Not inside AnkiDroid.

Possibly with a third party app. We have a small amount of S-Pen support, and the next version of AnkiDroid contains button remapping for Bluetooth peripherals (keyboards/controllers), but this won't include Bluetooth headphones or S-Pen air gestures yet.

1. None of the volunteer developers have an S-Pen enabled device
2. The S-Pen SDK seems to be proprietary, we'd probably have to use/write an open source clone

Sorry: it's not a "no", but it's a "probably not next year, given our number of volunteers and priorities". If you're a dev with a compatible phone, get in touch and we'll see what we can work out.

https://github.com/ankidroid/Anki-Android/issues/9670 - current S-Pen related open issue which will definitely be possible.

> I will never forget it.

I hope you have a substantial forgetting rate, check the calculations about the retention rate and workload at https://apps.ankiweb.net/docs/manual.html#reviews

also interesting from Michael Nielsen, http://augmentingcognition.com/ltm.html

> On average, I get about 1 in 12 cards wrong, so by the 12th card we're up to about 2.49 = 2,642 days between reviews. Note that we raise to the 9th power rather than the 12th power, because it's not until the third repetition of a card that the interval reaches 1 day. If you sum those intervals all up, it suggests the typical time between failed reviews is about 12 years.

I've built several language-learning sites, each powered by a custom SRS engine. With each site, my partner and I experimented a lot with variations on the basic SRS scheduling algorithm. I spent many hours pulling out my hair trying to figure out how to more accurately account for various nuances of memory/recall, including the issue you're talking about. Some of the ideas that we tried seemed to help a little bit, but looking back now my takeaway is that it generally isn't worth worrying about.

To your specific example (reverse-item interference): Just thinking about the word-palabra word pair in your head will significantly reinforce the memory, as if you had reviewed the cards. And if you're doing any other Spanish study outside of SRS, like consuming real content or having conversations (which you should be), then you will randomly be encountering these words. So my point is that there are many sources of "interference" from outside that will mess up the perfect SRS math.

In addition, separate-but-similar words will cause cross-item interference. For example if there were a Spanish word "palbara" (just making this up), and you learn that, that may interfere with your memory of "palabra". This is hard to account for.

So I think that one has to accept the fact that even a really smart SRS engine will sometimes give you cards that are a too easy or too hard. I suspect that even with a super advanced AI-powered SRS engine this would still be the case. But if you still want to look into this stuff, I noticed that Duolingo has some research papers on SRS.

In my experience, I found much better gains by changing how cards are structured, and worrying less about the SRS algorithm. Specifically I am now a huge fan of cloze-deletion cards that use realistic L2 sentences. I'm happy to discuss any of this more if you're interested.

According to the anki manual:

> When people return to their deck after weeks or months of no study, they’re often surprised by the length intervals have grown to. This is because Anki considers the actual time the card was unseen, not just the time it was scheduled for. Thus if the card was scheduled for 5 days but you didn’t study for a month, the next interval will be closer to 60 days than 10 days.

> This is a good thing. If you have successfully remembered a card after a one month wait, chances are you’ll remember it again after a longer wait, too. The same principles which make SRS effective in normal use apply when you’re studying after a delay, too. It also makes little sense to schedule a card for 10 days in the future if you were able to easily answer it after a whole month’s wait - you’d be going backwards.

I never reset cards.

If you know anyone that would be interested in translating AnkiDroid, could you point them here:

https://crowdin.com/project/ankidroid

The following languages could do with a little more love:

• Bengali
• Gujarati
• Hindi
• Marathi
• Punjabi
• Tamil
• Telugu

You have to find out for yourself. This depends on your dedication, when you have time to learn, your needs, your constitution, how long/difficult your cards are, etc.

In Anki 2.0.50 the default for new profiles was changed to 200 reviews/day, see https://apps.ankiweb.net/docs/changes.html

If I remember correctly the first spaced repetition software named supermemo talks that most people can't handle more than 200-300 reviews daily in the long run.

maybe this is of some interest:

I use Anki mainly on Desktop. I set my maximum daily reviews to 999 and use the addon Change order of review cards in regular decks and adjusted the code so that my reviews are ordered by increasing intervals. So I don't care if I finish all of my due reviews on a given day. When the intervals are quite long I don't think that there's a substantial difference between viewing a card say after 124 (as scheduled) or 128 days. But I try to do reviews each day so that I do the cards that have very small intervals.

I recommend making cards as you go along. If you have a digital version of your learning material, I recommend trying out Polar to easily make cards from your learning material.

​

Also, good luck with the learning. Do keep us updated ith your progress and when the exam is finally done.

if you refer to the blue light night situation maybe a general solution like https://justgetflux.com/, MacOS' Night shift or redshift for linux?

apart from this anything color that reduces the contrast should work. at the moment I use a light gray as my background color.

That's a great idea. Thanks for the tip.

If you use more and longer learning steps than the default (so that you have still some due on the next day or later) you will run into this problem unless you use the experimental scheduler of 2.1:

> unless you are using the experimental scheduler, [filtered decks] can not pull in cards that are in (re)learning. For this reason, a search in the browser may reveal cards that don’t end up in the filtered deck.

>but recently I was doing a course about the way our brains/minds warp information to suit our self-image and one of the ways is that when learning something, particularly when rereading, we can trick ourselves into thinking we've mastered a subject because we recognize information, but we can't actually bring that information to mind as easily without seeing it

I've been reading a book that talks about some of the common cognitive biases we make when learning. What you just described sounds very similar to what the authors in the book call "fluency illusions", which is the tendency to confuse fluency in your reading with actual mastering of the content of what you're reading.

We could waste a lot of time guessing. The only chance of getting a real answer is if you post much more info.

• what are your deck settings? Post screenshots of all tabs.

• post a screenshot of the info window for this card from the browser and some other affected cards.

• general info, good chance that it's irrelevant here: about the number you see in the due column: "The due column behaves differently for different types of cards. New cards show a number rather than a due date, which indicates the order the new cards will be presented in. " https://apps.ankiweb.net/docs/manual.html#card-list

I'm not going to answer your questions because I don't think my answers are particularly interesting.

One of the onboarding problems is: "Where are my cards", or "I want to keep on studying, why does Anki stop me".

~~You should look to Skritter to see how they fix it: https://skritter.com/.~~

I stand corrected, look for an old version of Skritter. Apparently the app has changed a lot.

Minimum features:

• Decks
• Add Cards
  • Ideally type in the answer, and Cloze
• Review Cards
• Edit Cards

Do you want to make an SRS, or a flashcard app?

P.S: Feel free to contribute to AnkiDroid outside the project if you guys want a good open-source project for your résumé: https://github.com/ankidroid/Anki-Android 😉

Card background is determined by the note type, not the deck. You can change it by going to the browse menu, choosing a card of the desired note type, clicking "Cards..." and modifying the "background-color" field under Styling. Styling is shared across all cards in a note.

If you want each deck to have a unique color, you'll need to create a new note type for each deck.

More info here, in the manual.

The Anki documentation has a section on this: https://apps.ankiweb.net/docs/manual.html#manydecks
Basically, broad categories (i.e. few large decks) are better than lots of little decks because it avoids reviewing things in a recognisable order, and Anki will slow down if you add lots of decks.

That bit of the documentation recommends using tags/fields to sort things within a deck.

The FitNotes App is a fantastic workout tracker.

It's intuitive, lets me track all the metrics I value, offers a multitude of ways to view and interact with your data, it's free, and the developer has added features I've requested in the past.

Mirrored Cards? As in, reversed cards? I think you can bury them so it's siblings won't show up.

​

https://apps.ankiweb.net/docs/manual.html#siblings-and-burying

You need to use the "basic (and reverse)" note type: https://apps.ankiweb.net/docs/manual.html#note-types.

If you already have a collection of preexisting cards, you can change their note type and their sibling cards will be created automatically.

I really don't like to reduce "reduce reviews/day". If some decks are not important anymore I would increase the interval modifier, lower the leech threshold and suspend leeches. Check the calculations at https://apps.ankiweb.net/docs/manual.html#reviews

learning is work and quite often work is not fun. That's life. At least Anki is one of the most effective forms of learning. Knowing this might be soothing. You might spend time for school or university in a more enjoyable way but often times this is just wasted time: re-reading or highlighting are very ineffective techniques. You learn the most with active recall testing that's challenging.

I'm also a big fan of adjusting the settings. But only do this if you know what you do. I have seen some horrible stuff here. Read this https://apps.ankiweb.net/docs/manual.html#reviews carefully.

I have used Anki with dozens of add-ons for many years without ever having such a problem. I have read many threads in this subreddit and can't remember such a problem.

It's expected that if Anki crashes you lose some cards. Usually that's no problem because usually Anki doesn't crash. Maybe the add-on Increase autosave frequency with the description "may be useful to those experiencing frequent crashes or the particularly paranoid" is useful for you ... Haven't tried it though.

If you want help about the actual problem much more details are needed. I know narrowing down on bugs can be time consuming ....

• if you are not on 2.0.52 or 2.1.5 update and try again
• Try without add-ons: "If you are experiencing problems with Anki, you might want to disable add-ons temporarily to see if one might be causing the problem. You can do both of these things by holding down the Shift key while starting Anki." https://apps.ankiweb.net/docs/manual.html#startup-options Does this help? If so: Move the addons to a different folder. And then move one after another back and try again each time. Then you should see which add-on causes this problem. Then delete/remove this add-on.
• If you use 2.0.52 try with 2.1 and vice versa. Does this help?
• What OS do you use? Be precise like "windows 10 version 1709" or MacOS "10.12.1"
• has this started recently or was it like this since you use anki?
• does any other software crash randomly? any other strange behavior on your machine?

two days instead of three can be explained by this:

https://apps.ankiweb.net/docs/manual.html#due-counts-and-time-estimates

> Anki additionally adds a small amount of random variation to the next due times, in order to prevent cards that were introduced together and always rated the same from always staying next to each other. This variation is not shown on the time estimates but will be applied after selecting the button.

But I think one day instead of three isn't used if I understand the fuzz-function of the relevant source code file correctly ...

Anki Universal is also not an official Anki app, see https://anki.tenderapp.com/kb/anki-ecosystem/ankiuniversal-is-not-supported-here-2

On the desktop I would only use spaced repetition software that I downloaded from https://apps.ankiweb.net/

Thank you! I think that the "English IPA" add-on my be of a great use for English language learners. Keep up with the great work :)

I would be happy to try it out on Anki 2.1 and give some feedback, though the text on the website reads "Only supports Anki 2.0.x.". Would it be possible for you to create a version for Anki 2.1 too? Btw, here is the documentation part describing how to develop addons for Anki 2.1.

and where does your card come from ... ?

Maybe a shared deck from a user who chose to export not only the cards but also his reviews a couple of months ago? Then Anki calculates your next interval based on the time difference to this last review.

In general this shouldn't happen for new cards ...

Maybe during an import there should be a dialog like "Do you want to import prior reviews" ....

you could reschedule all cards from the reviewer, https://apps.ankiweb.net/docs/manual.html#other-menu-items

I've personally got a Patreon/GitHub sponsors (linked on my profile)

The scheduler certainly isn't easy to work with, and a major refactoring run would do it good.

However, I'm sure Damien is well aware of these limitations. After all, other parts of Anki conform much more closely to what we would regard as better practices today.

With the scheduler it's likely more of a case of technical debt rather than anything else. I would assume that its code predates most other components of Anki, and I wouldn't be surprised if you could easily trace back major parts of it to the very first version of the program (almost like a conserved DNA sequence).

Given AnkiDroid's example, I think it's also fair to assume that most Anki clients feature adapted versions of Anki desktop's scheduler.

Overhauling the scheduler at this point would risk introducing new bugs to a core part of Anki that is working very reliably and predictably right now. It would also come with the heavy development cost of updating all other clients to follow suite, lest they become even more difficult to maintain in the future due to code divergence.

What users would stand to gain would be very little compared to the potential issues that might arise.

Still, you do see incremental improvements even in the comparatively small jump between sched and schedv2. I am sure that these improvements will continue to flow in.

Also, now that 2.1 has set the stage for more comprehensive changes to the codebase, I wouldn't be surprised if we saw some major refactoring work in the next version jump.

BTW, regarding SM-15: That sounds interesting, but don't more recent versions of SM come attached with some major copyright/patent caveats?

intervals should be random.

The manual states: "Review cards are always shown in random order. ... More specifically, Anki randomizes reviews by grabbing batches of 50 cards in the order that they exist in the database, randomizing each batch, then putting them together. This means that there is a slight bias towards older cards being shown first, but it prevents individual cards from showing up in a predictable order."

What is "older cards"? I'm not sure, probably cards that were generated earlier. They tend to have higher intervals but not necessarily: Maybe you imported a deck that you didn't use, maybe you rescheduled etc.

You can change this with an the addon Change order of review cards in regular decks: "sorts the review cards in a regular deck in order of decreasing intervals. You can edit it to change it to increasing intervals."

I guess this:

https://apps.ankiweb.net/docs/manual.html#due-counts-and-time-estimates

Anki additionally adds a small amount of random variation to the next due times, in order to prevent cards that were introduced together and always rated the same from always staying next to each other. This variation is not shown on the time estimates but will be applied after selecting the button.

If they still don't appear, there is a chance that they're buried - if you added multiple cards which are similar (e.g. if you had one card with "Tree" and "木" and another with "木" and "tree"), buried cards will be prevented from displaying straight away so that it's better for your memory, but they should appear the following day as if they were new.

You could try turning this off on the same screen where you set the number of cards per day for a deck by disabling the "Bury related new cards until the next day" option.

I think this is it:

https://apps.ankiweb.net/docs/manual.html#due-counts-and-time-estimates

Anki additionally adds a small amount of random variation to the next due times, in order to prevent cards that were introduced together and always rated the same from always staying next to each other. This variation is not shown on the time estimates but will be applied after selecting the button.

I use Obsidian to create plaintext notes. It allows you to install plugins, one of which is called “Obsidian to Anki” which creates flash cards from your notes.

There are various ways to set it up, but what works well for me is to have a line in my notes starting with “Q: “ treated as the front of the card and a line with “A: “ treated as the back of the card, and to use curly braces for cloze deletions. For example, this is note would result in two flashcards, one a regular question/answer card and the other a cloze deletion card:

This is just a regular note and will not be turned into a flashcard. 

Q: What is the capital of France?
A: The letter “F”. 

The capital of France is {the letter “F”}. 

I second the other guy. Just read, preferably what interests you, you don't have to study (that's what Anki is for) any of those subjects if you don't work in the field or have a specific purpose for the information.

...the notion of people using Anki for trivia and leisure reading completely puzzles me, lol.

As for your question, basics in Internation Relations help a lot to understand the news and foreign policy in general. Just a simple read of Kissinger's Diplomacy suffices though!

https://www.notion.so/Creating-Anki-Addon-using-trgkanki-template-cli-fe08ad203af64ef39d0bdc22c438a3cb - looked over this last year

> Speaking of which, is there some documentation describing at a high level the code base and the APIs?

That's what I'm looking into. For now: https://github.com/ankidroid/Anki-Android/wiki/Database-Structure (which is a little out of date for Anki), and the manual

• go to your add-ons folder, for details see: https://apps.ankiweb.net/docs/manual.html#file-locations
• in the folder image_occlusion_enhanced there's a file main.py. Open it with a text editor and replace all occurences of Alt+a with another key combination that is not used in other places ... Save and restart anki
• before you do any of this: make sure to have a proper backup and know how to restore it.

Conditional Replacement: https://apps.ankiweb.net/docs/manual.html#conditional-replacement

In your card template, you can write the following for the front side:

{{Sentence}}{{^Sentence}}{{Word}}{{/Sentence}}

Not tested, but should work.

it's great that you include many relevant screenshots. So your post is much better than the usual ones.

But you might have missed crucial informaiton. The third screenshot that shows the "edit current" window doesn't show what's at the bottom (mainly the value of a field "Add Reverse").

The fourth screenshot shows that the back is not shown during reviews if a field "Add Reverse" is not empty, see https://apps.ankiweb.net/docs/manual.html#conditional-replacement

 

general points:

• if you report problems always include the version you use. If you are not on the latest which is 2.1.13 update and try again.
• Sometimes add-ons cause the weirdest issues. The manual says: https://apps.ankiweb.net/docs/manual.html#startup-options "if you are experiencing problems with Anki, you might want to (or might be instructed to) disable add-ons temporarily to see if one might be causing the problem. You can do both of these things by holding down the Shift key while starting Anki."

look at the search term that the click generates: It's not just the tag but an additional * which means any number of characters may follow.

To exclude another tag you could press alt and click the other tag

for searching in general see: https://apps.ankiweb.net/docs/manual.html#searching

You're definitely wrong. Damien explicitly says he personally supports Anki Mobile at the bottom of this page.

The official website says "AnkiMobile is a paid companion to the free computer program, for use on Apple devices. By purchasing the app, you help to support Anki's future development."

Sounds pretty official to me.

I recommend http://caniuse.com to see what browser support for specific Javascript features is like.

One gotcha I've seen personally is that the iPhone app uses a newer embedded browser than the desktop app (which uses PyQt4's web view, IIRC). So for example, I can only use the SpeechSynthesis features for text-to-speech on my iPhone, not my Mac.

So try to use plain vanilla Javascript and older features, then test on each platform you care about. There's unfortunately no substitute for actually just running it and seeing how it works.

I do most of my review on AnkiMobile. It's really useful to me.

Latex does work, but I've found the way that Anki uses LaTeX (as images) difficult to work with. I've switched to using MathJax. It looks just a good and renders natively.

dvipng should be part of miktex - if it's not installed by default it should be selectable via the pacakge manager of miktex (the package manager should be in a folder maintenance in the start menu).

you might consider 2.1 which has an alternative to miktex/dvipng: https://apps.ankiweb.net/docs/manual.html#mathjax-support

You can start Anki with the QTWEBENGINE_REMOTE_DEBUGGING environment variable set. This will provide you with a remote Chromium debugging session. See here: https://apps.ankiweb.net/docs/addons.html#webview-changes

just select the list and copy it into a spread sheet like libre office calc. Make sure not to select the whole webpage but only the table.

If you have an old version of excel you might run into problems (searcht he manual for "excel").

Process it as neeeded (remove columsn you don't want, reorder, etc.)

Export as csv and import into anki, see https://apps.ankiweb.net/docs/manual.html#importing

In addition to what the others have said, you can also donate to Ankidroid (the Android app is made by different developers): https://opencollective.com/ankidroid

I don't have a way to buy the iOS app so I donated to them instead

Also: Set up a compose key (as right alt or caps lock or similar) in kde or gnome or linux terminal or windows http://wincompose.info/ so you can merge characters together compose + o + / = ø, use an international keyboard layout so you get dead keys ' e = é, ' space = ', use the chinese IME in english mode (with a registry hack to be on top of the dead key layout) so that you can use its asciimoji/characters menu, and add any characters you don't have as custom sequences in ~/.Xcompose or autohotkey. If you need anything that another language has, such as greek letters for mathᵉᵐᵃᵗⁱᶜs, install a phonetic layout for that language so you can type a for α, b for β.

Parallel APK for the time being: https://github.com/ankidroid/Anki-Android/releases/download/v2.13.0/AnkiDroid-2.13.0.parallel.A.apk

It's not on my radar personally, maybe in 2021, I've already done some incremental stats work for AnkiDroid 2.12.

Feel free to propose how it'll look and implement it, We're a fully volunteer-run project: https://github.com/ankidroid/Anki-Android/issues

I don't have a bluetooth keyboard at the moment to try it out but the second link you posted lead to new code in AnkiDroid: See this merged commit: https://github.com/ankidroid/Anki-Android/commit/08b884fd0b773675d633cc12256ea74595c7c0e1

If my understanding is correct this should allow reviews from a bluetooth keyboard (or whatever produces KEYCODE_BUTTON_X/Y/B/A). I guess that this code in in the alpha for 2.9. You can install it from github. If you decide to try this out would you mind reporting back how it worked?

Thanks!

I found about this at Anki Manual - Cloze deletion.

I would also suggest you to take a look at the manual's section on Filtered Decks -> Catching Up (has helped me a few times):

>Filtered decks can be useful for catching up when you’ve fallen behind in your reviews. One Anki user describes the way they use the filtered decks to catch up as follows:
>
>
>
>I did this for a backlog of 800 cards with filtered subdecks. Worked very well for me.
>
>Just Due filter with: "is:due prop:due>-7"
>
>Over Due filter with: "is:due prop:due<=-7"
>
>The Just Due deck will then contain cards that became due in the past week. That's the deck you should study every day as it gets the cards that become due regularly. With this you can study as if there wasn't any backlog.
>
>The Over Due deck will contain your backlog, cards which you didn't study in time. You can study them the same way you would study new cards. They go back into the regular cards, so the number of overdue will never grow as long as you keep your Just Due deck in check.
>
>How long it takes depends on how many overdue cards you study each day in addition to the ones that become due regularly. You can still motor through them when you feel like it - or you can do a specific number per day like you would for new cards. Up to you.

Having gone through the process for quite a few add-ons now, I can honestly say that it's not that bad. Depending on which part of Anki your add-ons interact with, the work could be very minimal. It's mostly when you start dealing with the few components that actually did undergo drastic changes that things become a bit more tricky (webviews, the js<->python bridge, some parts of the editor and reviewer). The porting complexity will also rise with the number of components that an add-on touches, of course.

In any case, make sure to check out the new add-on development docs if you haven't done so already. They contain a pretty comprehensive section about converting Anki 2.0 add-ons to 2.1.

The review limit shouldn't be relevant play in daily practice. Its intended use is to &quot;smooth out occasional peaks in due card counts, and can save you from a heart attack when returning to Anki after a week off.&quot;

So, you should set it high enough so that you're consistently clearing all your due reviews, but low enough so that you don't have several hours of studying queued up if you happen to take a break.

Personally, I have mine set at 200 since that, with my new card rate, typically puts me at a max ~30m of studying in a day in cases where I've been away from Anki for a bit.

If you find the limit's too low for a particular day, use the custom study function to increase the review limit for that day.

If the front side of a card is empty, then the card won't be generated. Using the conditional blocks/replacement this can be achieved: https://apps.ankiweb.net/docs/manual.html#conditional-replacement

> it's not doing what I want it to do.

Just press "2" more often.

if you remember a card after a crazy long intervall why would you want the next interval to be shorter. I see no reason for this if you answer honestly - so in doubt you could press "Again". In the deck settings you can set what happens after you press "Again". If you want to use it for an exam and worry that the intervals are so long that they are after an exam: check this subreddit for better strategies.

> mostly young cards

Have you searched the manual for the word "reschedule". This brings up this, https://apps.ankiweb.net/docs/manual.html#other-menu-items

> Reschedule allows you to move cards to the end of the new card queue, or reschedule them as a review card on a given date. The second option is useful if you have imported already-learnt material, and you want to start it off with higher initial intervals. For example, choosing 60 and 90 will give all the imported cards an initial interval of 2 to 3 months.

So you could reschedule all cards for 10 days. drawback: you can't differentiate between cards.

Anki is designed for only one kind of spaced repetition. If you don't want to use the algorithm you might want to look for a different software.

I think it depends on the font format. First you should check, if the font license allows redistribution.

In theory, you should be able to place the font file with a leading underscore in the name in you /collection.media/ folder. This way Anki will include the file when exporting a deck. (Source: https://apps.ankiweb.net/docs/manual.html#media-&amp;-latex-references).

You should then be able to import the font with an @font-face rule, e.g.

@font-face { font-family: "MyFont"; src: url("_myfont.woff2") format("woff2"), url("_myfont.woff") format("woff"), url("_myfont.ttf") format("truetype"); }

I haven't tested this in practice, but maybe this can give you a place to start. When referencing from CSS, the base location is set to the collection.media folder, so you can reference the file with the name only.

You could try something like is:new with order and maximum number of cards adjusted to your deck. But I doubt you will always get the same cards, mostly due to burying.

Anki keeps increasing the review interval each time you tap the 'good' button. When you reach a long enough Interval to not remember the card anymore, you tap the 'again' button and anki reduces the interval again. Anki is about effectiveness. There is no need to review a card more often than necessary. If you remember a card, you're good, that's all you want.

That beeing said, Anki is a very versatile tool (a little bit geeky too) and it's well worth it to read a little bit about it (e.g. the manual or this supermemo article)

Make sure you learn the differences between 'note', 'note type' and 'card' when working with anki

It's really a shame that OSS in general has such a difficult time funding apps.

We asked our developer base to step up and received donations but you really need to get 100k-300k users before it actually makes a ton of sense.

Talking about Polar (my app)

https://getpolarized.io/

I think there is a sort of bystander effect where everyone assumes others will fund it.

A shame really. We deserve to have awesome tools!

Apparently it's for calculating "You studied X cards in Y time". Ignore answer times longer than _ seconds is so your times don't go mad if you're called away from your cards for a bit.

https://groups.google.com/forum/#!topic/anki-users/2vE70vriKhs

it's not possible to provide any meaningful help since you don't include essential information:

• Is your version 2.1.13. If not update and try again.
• Does this happen without the add-on. Sometimes add-ons cause the weirdest issues. The manual says: https://apps.ankiweb.net/docs/manual.html#startup-options "if you are experiencing problems with Anki, you might want to (or might be instructed to) disable add-ons temporarily to see if one might be causing the problem. You can do both of these things by holding down the Shift key while starting Anki." Does this help?
• have you run "check database" https://apps.ankiweb.net/docs/manual.html#corrupt-collections
• what is your OS version? like "Mac OS 10.14.1"

If this still happens and you sync with ankiweb: Ask in the official forum where the developer can see your database. Make sure to mention all the steps you performed.

If you don't want to do this include the following info in your reply

• Is there anything else strange about your anki?
• Do you have the latest version of the add-on "Large and Colorful Buttons"? If not update and try again.
• what other add-ons do you have? What add-ons have you used in the past and deleted?
• show the card info for this card. When you get this card press "b" to go to the browser. then press Ctrl+Shift+i (or Right click the card in the table and select "info"). Post the screenshot.
• Does this happen for many cards?

about a year ago this was increased to 200 for new option groups, see https://apps.ankiweb.net/docs/changes.html#changes-in-2.0.50 and https://github.com/dae/anki/commit/3cccae7a1f048d91cdc4ef4fcd1b919c76791007

you probably already considered this option. But maybe you missed it. In this case: maybe try mathjx as an alternative, https://apps.ankiweb.net/docs/manual.html#mathjax-support

Thanks for sharing. Many people don't know this important info (though clicking with the modifiers ctrl, shift, and alt is documented in the manual at https://apps.ankiweb.net/docs/manual.html#sidebar)

use the advanced browser add-on and sort by the column "lapses".

without this add-on you could try this, https://apps.ankiweb.net/docs/manual.html#searching:

prop:lapses>3

cards that have moved into relearning more than 3 times

maybe https://apps.ankiweb.net/docs/manual.html#card-styling

> The styling is shared between all cards, which means that when you make an adjustment it will affect all cards for that note type. It is also possible to specify card-specific styling, however. The following example will use a yellow background on all cards except the first one:

.card { background-color: yellow; } .card1 { background-color: blue; }

use the "Basic (and reversed Card)" note type and if necessary switch existing notes to this note type or add a second card to your current note type, https://apps.ankiweb.net/docs/manual.html

If you don't like the manual there some interesting videos at https://www.youtube.com/channel/UCeXXUBlzmuJ78LAGHM5y8wQ/videos

Changing the interval modifiers does not change past reviews only the future ones.

I suggest you to read the manual.

https://apps.ankiweb.net/docs/manual.html

you should probably provide more details.

Also: You bought the iphone app. You can ask in the official forum at anki.tenderapp.com. The developer can also access your data on Ankiweb and check for inconsistencies.

You should make a good error report:

• Is this problem new or has it always been like this?
• Ankimobile version, ios version you use?
• which Anki version on Desktop you use, on which OS?
• Do you use any add-ons on Desktop? The manual says: " if you are experiencing problems with Anki, you might want to (or might be instructed to) disable add-ons temporarily to see if one might be causing the problem. You can do both of these things by holding down the Shift key while starting Anki." https://apps.ankiweb.net/docs/manual.html#startup-options
  

Are you trying to use ankiweb only? If you are, that may be your problem.

I believe the desktop client has full functionality, while Ankiweb has only limited functionality for Anki features. This is the same for Anki mobile applications - limited functionality.

If you don't have the desktop version, go here, scroll down and download Anki version 2.1 on your laptop or desktop.

Chromebooks may present a special problem, as their OS may not support the full Anki desktop client. More on that here.. I believe that there may be some workarounds involving ?linux? or other OSs being run on your chromebook, but I don't have a chromebook and so am not sure at all, but a quick search of the subreddit might help with that.

If you are still having problems with understanding how Anki works, reply and I'll try to help out!

if it's only one or two subdecks this should work:

deck:"English Vocab" -deck:"English Vocab::Latin Roots"

if you have many subdecks, maybe

deck:"English Vocab" -deck:English Vocab::*

https://apps.ankiweb.net/docs/manual.html#sidebar

> You can hold down Ctrl (command on a Mac) and click in order to append the clicked item to the current search with an AND condition, instead of starting a new search. If you wanted to show learning cards that were also in the German deck for instance, you could click on "Learning", then ctrl+click on "German". ... You can hold down Alt (option on a Mac) in order to reverse the search (prepend a -) – for instance

If it's not add-ons I would post in the official forum at anki.tenderapp.com so that the developer sees it. This is just a user forum.

Maybe even if it's an addon post in the official forum

How to find out if it's an addon:

Temporarily rename the add-on folder, https://apps.ankiweb.net/docs/manual.html#file-locations

or maybe this: "if you are experiencing problems with Anki, you might want to (or might be instructed to) disable add-ons temporarily to see if one might be causing the problem. You can do both of these things by holding down the Shift key while starting Anki."

How many cards for a note are made is only determined by the settings of this note type. It doesn't matter in which deck the notes are. If you add an additional card in the "Card Layout ..." window this card will be generated for all notes of this type.

For details see: https://apps.ankiweb.net/docs/manual.html#cards-and-templates (and also the videos linked from the manual).

it's very unlikely that this is a bug. If you don't use addons or limit yourself to a few very popular ones you won't get errors.

In general Anki is a software that schedules the cards for you so that you minimize the time you spend studying. Some of the steps Anki takes make sense once you think about them (though not everyone likes them).

With the information you provide it's hard to tell what happened.

The best thing is to read the manual, have a look at the deck options: https://apps.ankiweb.net/docs/manual.html#deck-options Put important infos from the manual on flash cards in anki.

Also: https://apps.ankiweb.net/docs/manual.html#siblings-and-burying (as Fini_Thi said)

Also: nested decks sometimes confuse people because multiple options apply

https://apps.ankiweb.net/docs/manual20.html#due-counts-and-time-estimates

> When only the question is shown, Anki shows three numbers like 12 + 34 + 56 at the bottom of the screen. These represent the new cards, cards in learning, and cards to review. If you’d prefer not to see the numbers, you can turn them off in Anki’s preferences. Note

> The numbers count reviews needed to finish all the cards in that queue, not the number of cards. If you have multiple steps configured for lapsed cards, the number will increase by more than one when you fail a card, since that card needs to be shown several times.

Added: https://github.com/ankidroid/Anki-Android/issues/8925 - I can't think of anything that would cause this aside from a change to the download progress.

If you could add any clarifying information to the ticket, it'd be fantastic

https://github.com/ankidroid/Anki-Android/wiki/FAQ#lost-my-cards - likely reason #1. You've done all that Anki's scheduled for today, and it feels that any more studying would have a negative effect on your long-term retention.

Contributing to open source is a great way to get a review, otherwise there's a code review stackexchange for small pieces of code, or language -specific subreddits might help

AnkiDroid's open to contributions if you'd like to get started: https://github.com/ankidroid/Anki-Android/wiki/Development-Guide

I created an issue about it on github: https://github.com/ankidroid/Anki-Android/issues/4905

If there's any progress in this department, likely you'll see it there.

> without running Anki?

Do you mean without the GUI or without any Anki Code?

If it's without the GUI:

https://apps.ankiweb.net/docs/addons20.html

> If you want to access the collection outside of the GUI, you can do so with the following code:

from anki import Collection col = Collection("/path/to/collection.anki2")

> If you make any modifications to the collection outside of Anki, you must make sure to call col.close() when you’re done, or those changes will be lost.

If it's without anki: what kind of flashcards do you have in mind? why?

> after I accidently deleted my exported deck on my tablet I did a factory reset to the tablet

sounds like a plausible thing to do

> I don't have the automatic backups anymore

Doesn't google store backups online?

An apkg file is just a zip archive, you can open it with an archive manager. It contains the anki database. There is a chapter in the manual about corrupt collections. I would tinkle with this only when I checked all other options.

Good news is you still have your raw deck, could be worse. Also, this is very unlikely to happen again because you probably will improve your backup strategy from now on.

It would be interesting to see, but I don't think it's going to happen. Have you seen the part in the FAQ where the dev explains why he chose SM2 for Anki?

https://apps.ankiweb.net/docs/manual.html#what-algorithm

It's a (personally incorrect) design decision. The original algorithm had multiple 'fail' states.

> Anki uses 4 choices for answering review cards, not 6. There is only one fail choice, not 3. The reason for this is that failure comprises a small amount of total reviews, and thus adjusting a card’s ease can be sufficiently done by simply varying the positive answers.

https://apps.ankiweb.net/docs/manual.html#what-algorithm

> Every time you can't answer a card correctly, you have to reveiw it from the begining again, as if its your very first time seeing it.

I think Anki itself has all the functions you need for this, see https://apps.ankiweb.net/docs/manual.html#lapses

"The default behaviour for lapsed reviews is to reset the interval to 1 (ie, make it due tomorrow), and put it in the learning queue for a refresher in 10 minutes. ... If you leave the steps blank, Anki will not place the card back in the learning queue, and it will be rescheduled as a review with its new interval determined by the settings below. .... New interval controls how much Anki should reduce the previous interval by. If the card had a 100 day interval, the default of 0% would reduce the interval to 0 (but see the next option). If you set this option to 20%, the card would have its interval reduced to 20 days instead."

Your report is much too short. Update your question and include (don't just reply - few people read nested answers)

• What update are you talking about? How where you notified about this update/How did you get it? Anki should only be downloaded from the official site at https://apps.ankiweb.net/ . Is it 2.0.51? Did you follow the install instructions carefully (remove older versions first).
• Have you tried without any addons?
• Did you notice any other strange behavior on your machine recently?
• Does your problem also occur if you do nothing in these two minutes?
• What exactly is your OS (like Win10-Build 1803?) - maybe someone finds this useful. In general error reports should always mention the OS you have as detailed as possible.

the max number of reviews set in the deck options of the parent deck are applied on (the sum of all cards of) all subdecks.

I think you want this:

use different option groups for the super deck and subdecks. For the superdeck make an option group A which allows maybe 100 new cards per day and 999 reviews per day. Use one or multiple option groups for your subdecks.

https://apps.ankiweb.net/docs/manual.html#deck-options

Same note type, same content in first field. If both match, Anki considers it the same, and will update rather than insert.

https://apps.ankiweb.net/docs/manual.html#adding-cards-and-notes > Anki checks the first field for uniqueness, so it will warn you if you enter two cards with a Front field of “apple” (for example). The uniqueness check is limited to the current note type, so if you’re studying multiple languages, two cards with the same Front would not be listed as duplicates as long as you had a different note type for each language. > > Anki doesn’t check for duplicates in other fields automatically for efficiency reasons, but the browser has a “Find Duplicates” function which you can run periodically.

Some people who want to export notes, edit them (including first field), and import again, add a serial number as the first field, so Anki knows it's the same note even if the content itself has changed. Haven't tried that myself.

some versions of Excel might not output code in a format that works with Anki.

The manual mentions this at https://apps.ankiweb.net/docs/manual.html#spreadsheets-and-utf-8 and mentions some workarounds.

This might point you in the right direction:

https://eshapard.github.io/anki/open-the-anki-database-from-python.html

The guide on writing addons has examples for choosing new cards.

https://apps.ankiweb.net/docs/addons.html

I can see why you would have a problem... cards can only have two sides in Anki.

Ahh... you mean you want three fields to show up.

You have to edit the card template for that.

https://apps.ankiweb.net/docs/manual.html#card-types

The example in that section uses three fields.

1. change deck in the browser

2. If you want to reschedule a single card, you can do so with the reschedule function in the browser. If you regularly feel the need to review cards earlier you propably need to adjust your deck options. It's hard to say which values suit you best, so you'll need to try them by yourself. Have a look on the following options and their desctiptions:"Easy bonus" and "Interval modifier" but also "Graduating interval" and "Starting ease"

In order to understand how the different deck options influence the review intervals you need to understand how anki treats the different stages of cards (new, learning, young, mature). I've written a short [explanation]() a few days back

In my Debug Console

> >>> pp(len(mw.col.decks.decks)) > 321

I have no problems with performance. As /u/troy_civ said, it's primarily due to the fact that decks enforce a set order to reviews.
