It's an app for android that adjusts your phone screen according to sunrise and -set. The app turns the screen darker and gives it a red-ish tint in the evenings, making it easier to read without hurting your eyes, aswell as makes it easier to fall asleep after. I haven't found it using any extra battery either, definitely recommend it!
Edit: For those of you with computers or apple devices, f.lux is the way to go.
Twilight. I'm convinced I sleep better at night, especially when combined with f.lux on my computer and a LIFX bulb in my desk lamp.
EDIT: Link to the app on the Google Play store, in case anyone else wants to find it. Evidently it isn't available on iOS, but check out a similar app called Bluelight Filter. I don't even know if that one is available, but hopefully someone more Apple-savvy can find it.
There's an app called twilight which tints your screen a different shade for the time of the day, I've found it's very useful to making me not stay up late on my phone
There's an app called Twilight that filters the type of light coming from your screen so that it won't keep you up.
There's a version for desktop too, called Flux.
To get the questions out of the way (and promote other discussion)
1) Yes. Nova Launcher Prime and Tesla Unread. That's one way I'm aware of!
2) I've heard Twilight is pretty good
Speaking of blue light, i thought I'd bring this up. Try using f.lux for your computer, or twilight on android (I don't know about IOS).
What this app does is, reducing the blue light on your screen, it helps relaxing your eyes and makes you go to sleep easier, i really like these two apps, very important.
Twilight. It filters out blue light based on what time of day it is. This really helps for late night browsing without messing up your sleep (blue light late at night negatively affects your sleep). Here it is for android.
I use Twilight. Works pretty good. I set it up with specific hours instead of tracking sunset, and it becomes much less annoying. And oddly enough, no ads.
They make a version for Windows too, and probably other machines.
This is the issue for those who haven't seen it. (The dialog says "Screen overlay detected: To change this permission setting, you first have to turn off the screen overlay from Settings > Apps.")
Basically, it's a security feature. If you have an app currently using a screen overlay (i.e. using its "Draw over other apps" permission), like Twilight (a nighttime color-filtering app), you can't actually approve new permissions for other apps through the normal pop-up dialog. You either have to turn off the overlay and get the new app to re-request the permission, or manually set the permission.
I say this is a "security feature" because I believe the Android devs are concerned that a screen overlay app could obscure/overwrite the permissions dialog, and trick you into approving permissions. It would be nice to be able to say "I trust Twilight; don't let it stop these permission dialogs" but Android does not offer that level of granular control. So instead, I have the Twilight widget on my home screen, so I can quickly turn it off when I need to approve new permissions.
Not directly related, but I'm really enjoying <strong>Twilight</strong>, similar to <strong>f.lux</strong> (also awesome) for computers, it adjusts your screen to warmer tones gradually over time during the day so your natural sleep cycle is bothered less from staring at it in the evening and night. With prescribed stims and my hyperfocus always kicking in at night, it's really easy to lose track of time if I don't feel tired from staring at screens.
Staring at a screen isn't going to help you sleep. Installing an app like Twilight or CF.lumen can help by filtering out the blue light. Blue light prevents melatonin production. Melatonin is a hormone that regulates your sleep cycles.
It's called twilight.
The same effect can be achieved through free software.
Windows, Mac, iOS, Linux:
For Android I use an app called Twilight that is basically the same as f.lux. (I'm on my phone, so I don't have a link.)
Tem app de celular/computador que reduz o azulado da tela.
No android eu uso o Twilight
E no pc eu uso o Redshift(Linux). Eu não conheço nenhum pra windows, mas o nome genérico pra esses programas é blue light filter.
Essas coisas realmente funcionam, acredito que com um óculos também vá funcionar, mas se você for mão de vaca(que nem eu), talvez deva considerar essas opções
Basically it lowers the blue light your screen puts out when it's dark out, which is supposed to help you sleep better. I have mine set to start transitioning when the sun starts setting, which is really convenient.
F.lux doesn't exist on Android, but Twilight does the same without root and then there is CF Lumen which requires root access
Or you could get f.lux.
It does mess with the colours a little bit after the sun goes down (or whenever you set it to), as it starts blocking out blue light. But after getting that for my pc, and Twilight for my phone I have a lot less trouble getting to sleep after being on either.
It's the android equivalent of the excellent f.lux for PC. Enables you to use your smartphone at night and before sleepytime without staying awake for hours. It blocks the blue light after sundown so your brain won't get "stay awake" impulses from the screen of your smartphone.
I would just install Twilight if it's bothering you. I think You can pull a request on the Moto Community site too.
With the next major update of Chrome OS, you'll be able to use Android apps. Android has the excellent Twilight app. If your delicate little eyes can hold out until then, you may be able to save yourself the trouble of selling your device.
Since somebody else mentioned using melatonin to help you get to sleep:
f.lux on Windows, Mac OSX and Linux
Twilight on Android
Puts a red filter over the screen at designated times of the day to ensure the blue light from your phone or computer monitor is not going to disrupt melatonin production that naturally occurs once the sun is down.
Note that Twilight can interfere with app installations, and you may need to pause it to properly install apps. It can then be safely resumed.
I consider myself a heavy user and I manage to get 4-5 hours out of the device. Screen brightness almost constantly at 70%.
Download Twillight to save your eyes at night (and battery).
I installed Cloudy ROM and its pretty stable for me. Oh and don't think that iOS isn't crashing, it's just not telling the user like Android does.
Yes actually. You can use twilight if you're having trouble getting tired before bed. Flux if it is your pc keeping you up.
Not an FA but someone who has random hours at a lab.
A) Sleep in a dark room, you need to trick your body to thinking that it's night. An eye mask helps, but there are photoreceptors on your skin that tells you "yo it's daylight."
B) High frequency light hitting your eyes may also tell your body that it's daytime. If you need to use electronic devices near bedtime you should install programs that reduce the frequency of light displayed depending on the time. On computers/laptops, f.lux is a good option. Twilight for androids. iOS devices ~9.0ish have a native built in "night mode" that attempts to reduce the amount of high frequency light.
C) Try to get used to sleeping with ear plugs. Blocking out ambient noise allows for a more restful sleep.
This looks like Twilight which simulates a "blue light filter" similar to f.lux on desktops. The idea is that the reduction of blue light also reduces eye fatigue. Newer versions of Android and Windows 1 have this build in nowadays as a "Night Light" feature (probably iOS too now).
If you have Android apps enabled on your Chromebook, it seems that Twilight is finally working on the stable Chrome OS channel. I've been using it every night for the last week or so!
Twilight is a blue light filter for Android, dimming the screen at night. Works similarly to f.lux and iOS Night Shift.
I used to do research on circadian rhythms. I'd recommend the usual:
use bedroom for sleep only
drink water and stretch before bed, the big dramatic "I'm sleepy" stretches you see actors doing on TV
exercise frequently, both resistance training and conditioning/cardio
some people feel that other supplements help them sleep, you can try them cheaply enough... various herbs, extracts, etc. I'm not going to recommend anything specifically because I don't know that any of these have been shown to have a beneficial effect on sleep.
But most importantly as far as circadian science goes:
avoid blue light after the sun goes down. Install F.lux on your computer and use the color slider to make color temperature warmer at night
use Night Shift Mode on iPhones / iPads, and Twilight on Android - make sure to set your zip code or enable location monitoring so it knows when to do its thing
supplement with melatonin, you can get this cheap at any drug store and some grocery stores or Target, etc.
eat well, get enough protein and look into getting more ALA, EPA, and DHA in your diet
do not consume caffeine or other stimulants too late in the day. I avoid them after ~5pm unless I need to be up late for some reason. Also, avoid becoming dependent on needing these to "wake you up" in the morning.
get serious about your routine of when you wake up, when you go to bed, and try to stick to it
temperature and humidity of your room can affect sleep quality and whether you're snoring or tossing & turning, find what works best for you
I'm light sensitive too. I'd highly recommend flux for your laptop or desktop and twilight for your cell. It gets rid of the bright blue/higher frequency light and makes the screen more rosy red and less harsh. You can play with the settings to customize it. I have mine set to always be at nighttime levels.
These are some tips of the top of my head. Google 'sleep hygiene' for some more detailed advice.
I understand that feeling, I use android so my fix was to download the Twilight app (not related to the novel) I set up just the screen dim but if you don't like blue light you can change the color temperature+intensity too.
I can read stuff on my phone in the dark and play SS with it easier. I'm not sure about apple though but you can probably search it up.
Your phone should get Oreo soon enough and it has an option called "Night Light" in settings built-in, just wait a little, in meantime you can use apps like Twilight, it puts a tint on your screen and is inferior to built-in solutions or ones requiring root (for example, it will show up on screenshots you make).
There's also an app for Android called Twilight that does that, but it's free. Idk if it's for Apple too, but I'll get a link real quick
Edit: So it seems it isn't on apple. Here is the link to the play store though.
Not specifically for working, but my regular glasses have a blue light filter baked-in to the lenses. I got it because it cost me nothing.
It's not any better than Flux or Twilight. I imagine if I had to physically position myself in front of several different workstations throughout the day, the filter being attached to my head might come in handy.
Linkit tässä, niille jotka eivät tiedä ohjelmia: F.lux ja Twilight Androidille.
Tuo kyseinen käärmeöljy vuotaa joka paikaan. Kannabis alkaa olla yhtä ärsyttävä kuin joku kookosöljy.
I'm using this at the moment, trying to decide if it or Twilight are better. I was thinking it may save serious battery on OLED displays too (in theory both the brightness and the colour filter, since blue LEDs use something like 4x more power).
2.5 years playing and this is my first one. Sure, it could have been crit or speed ( :( ) but at least it wasn't flat HP.
Before you ask, the color is because I use the twilight app.
The twilight app is a must. The backlight on the nexus is really bright.
I like the Kindle. The e-ink screen is fantastic, for me. As for the economic viability of it, I check out books via Overdrive.
In view of declutter though, I don't see the Kindle as a magical cure for clutter. The big problem I had was that I accumulated books (both physical and digital) and never actually read them. Consequently, I decided to keep 4-6 books on my Kindle at any given time. Any more than that and I'd spend more time looking for what to read rather than reading.
That all written, as sherlock_logic wrote, unless you prefer the e-ink screen, use the Nexus 9. And, possibly consider an app like Twilight.
(PC Alternative: f.lux)
Also, here's the link to Twilight if anyone wants to easily get that.
Here. - Sorry, couldn't find an iPhone version.
Twilight: eine Android app die einen teil der Farben des Bildschirms filtert und so zu leichterem Einschlafen führt. Sehr empfehlenswert für Leute die vor dem Einschlafen noch auf dem smartphone zocken oder surfen!
What a good idea. I've thought about this but only now did I try it. I just sideloaded Twilight and it works PERFECTLY!!! I have it installed on my phone and on my Android TV device. Installed it on here and works, even when playing games :)
EDIT:Oh I see you're already using Twilight on your tablet. Just sideload it on the Go works WONDERFULLY! :)
For those on android, you can use Twilight to help with the issue, which was based off the PC (and Mac/Linux) program F.lux, which is also apparently available on iOS devices now. Just remember that you're still staring at light and likely stimulating your brain by being on your phone and whatnot
[link] for your computer and Twilight for Android. Both of these will filter out blue light at night allowing your brain to signal that it's bed time.
Some night owl friends have gone out camping and said that by 7:30pm they were ready for bed. Try having some "No artificial light" evenings. A bonfire or candles is fine.
Twilight - justerer automatisk farvetemperaturen, så du undgår stimulerende blåt lys om aftenen. Den har bestemt hjulpet på min søvn.
Red-shifting your display will also help greatly.
F.lux (Windows/Mac/Linux) and Twilight (Android) will do this for you automatically depending on the time of day and your location
Looks like the Twilight app (link). I use it on my phone to make the screen easier on my eyes at night, but it doesn't translate well into screenshots.
If you really want a pretty personal Android experience. Install Nova launcher and custom icons :)
Are you a f.lux user on desktop? Check out Twilight. It's flux for your phone! [link]
About malware, if your Android phone is fully updated you should have an issue. And all the warning are about installing apps from a third party source.
Oh also Google photos is a great free unlimited photo back up solution.
Amazon is advertising a pretty simple piece of software. Any android tablet or phone can be set up for low-blue light with some software. I've used Twilight in the past.
Now I just use some cheap prescription sunglasses with an orange 50% tint :)
> dark mode
In case you didn't know: Twilight App is filtering your phones colours according to sunrise and sunset, you don't need a dark mode anymore with this.
I haven't tried the flags option, but if your chromebook can access the play store try the Twilight app. It's what I use on my phone, and it works similar to f.lux on my chromebook.
Yes. That screenshot is a cringeworthy mess and TouchJizz hurts my eyes.
/uj Sam-Il-Sung hate aside, the filter (it's rather red) is supposed to reduce the blue light emitted by the display so it doesn't keep you awake too much (bilogical stuff, blah blah...). It should be this app.
/j Still not an excuse for not turning it off before taking a screenshot or not sacrificing that Sam-Il-Sung POS to DuARTe and getting a Nexus.
+1 for 5HTP. Get the 120mg ones from Healthpost and take one an hour or so before you go to bed. Works wonders for me. Also, start using red-shift apps on your phone.
Get screen filtering software for your computer and/or phone. The harsh blue light fucks with your circadian rhythm by tricking your mind into thinking its still day time. These filters strip out the blue light and give your screens a redder tint. It takes some getting used to, but it's well worth the effort. Now I can watch YouTube on my phone in bed without any impact on my sleep. There are lots of programs I'm sure, but I use f.lux on my computer and Twilight on my android phone.
>In other words, we need Android and iOS's permission model.
Sort of, but definitely not the same implementation.
>things like Classic Shell or f.lux are completely impossible under those permission models
I'm afraid I don't see the issue - couldn't f.lux simply have the "control monitor settings" permission and classic shell have the "replace standard menu action" permission? In fact the classic shell equivalent for android are replacement launchers, and those do exist! Also alternativeto.net suggested Twilight as an android alternative/equivalent to f.lux, and from my understanding it seems to do the same thing.
Eliminate as much blue light as possible a few hours before going to bed. Blue light makes your brain think there's still sunlight. Install f.lux on your computer and Twilight on your phone to filter a lot of it out. Make sure your house lights emit warm colors. You can even put on blue light blocking glasses if you really need to fall asleep.
Eliminating blue light can make it easier to fall asleep and get better sleep quality. Computers, phones, and large TVs really can disrupt sleep if not addressed properly.
Why don't you just use f.lux on your computer? For Androids there are apps that emulate that functionality.
I just keep nightime mode on when I browse Reddit. Coupled with Flux on my laptop and Twilight on my phone I just can't use the normal non-nightmode Reddit anymore. It's like looking at the surface of the sun!
I began sleeping more reliably and much better when I installed F.lux on my computer, and Twilight on my tablet. They work so well that I'll actually use them as a means to fall asleep.
> keep a cell phone with you that you can glance at every ten minutes or so, with the brightness turned down as low as possible to not ruin your night vision.
If you're on Android, you can install Twilight or CF.Lumen (which requires root, unlike Twilight). It turns the color temperature of your screen down after sunset (which, at least in my case, really helps you sleep better if you use your phone before bed). I use it all the time when I go out stargazing, too.
For iPhone you can use f.lux, which I also use on my PC.
I use OPX and use the "Twilight" app. It tints red-tints the screen which really helps with my eyes (especially at night-time / in low level light). Might be similar to the Lux app thats mentioned in this thread
Oh do you mean Android's night light feature
If so, [link] works on Android TV's
That makes more sense, but Dark mode is usually where apps replace their white backgrounds to grey or Black not the tone of the screen. Hopefully this app gets what you are trying to accomplish
It looks like it could be Twilight which people use to prevent strain on their eyes late at night. It helps you fall asleep at night 10/10.
This will not save any battery at all unless you have an AMOLED screen. And even then, the battery saving will be minimal. Turning down the backlight will save significantly more juice.
For the too bright eye strain, consider an app like Twilight
Is f.lux better than Redshift on Ubuntu or Twilight on Android? I was told that those two are as good as f.lux, though I'm no authority.
[link] not that hard to google really. It's an app that filters blue light (makes your screen have an orange tint) which is better for the eyes but fucks up recording.
Burnt like 10 stones on that crap.
At least I learned a valuable lesson about the relative utility of Chrono Turtle and Sun Quan.
Before anyone asks, the red is from this.
By screen dimming do you mean apps like Twilight that remove blue light? Twilight has helped me tremendously. I read in bed almost every night and the "night modes" in my reading apps just don't cut it.
Are you referring to Twilight?. If so, you can't really call it shitty just because you're not able to adjust the settings to exactly what you want them to be.
Ugh, I know that feeling.
Drink tonnes of caffeine and water during the day, helps keep you up.
F.lux and Twilight help me.
Don't go on your computer or phone before bed, it keeps you up.
>Inače samo da dodam na ovaj sav hype s LED rasvjetom
To o čemu članak govori je poznato već neko vrijeme, a u međuvremenu su se CFL žarulje i LED rasvjeta počeli proizvoditi u toplijim bojama upravo zbog tih istraživanja. Otvori bilo koji LED lightbulb na eBayu i vidit ćeš da je ponuđen u "cool white" i "warm white" varijanti. Zato ti je /u/cimomario napisao
>toplo bijele jer im je boja svjetla slična običnim žaruljama.
(inače zbog istog razloga se preporučuje koristiti softver poput f.luxa i Twilighta, pa eto, tko ne zna preporučam da instalira :)
I use Twilight, but I use Tasker to send it intents to start and stop the service (and now it's a plugin). So your claim of "those would kill the battery as they'd be running in the background non-stop" is not necessarily true. It doesn''t show up in my battery stats, nor does it show as occupying memory when the service is stopped.
By the way, did you read this?
(2) AMOLED screens: We have tested Twilight on an AMOLED screen for 2.5 years without any sign of depletion or over-burning. If properly configured Twilight causes less light emission (by enabling dimming) with more equal light distribution (dark areas of the screen such as the status bar get tinted). This may in fact increase your AMOLED screen life time.
Can you cite a source for your claims regarding Twilight and Lux?
There's some great programs to actually help with this.
f.lux works on Windows, Mac, and Linux. Also works for iPhone/iPad/iPod, but I believe it has to be jail broken.
Twilight is the Android version of f.lux. Does not require for it to be rooted.
Not on F-Droid, but Twilight has an option to detect such events and disables itself while on it, so not every app that uses overlays has this problem.
Not strictly PC, but you should consider getting a phone app that does a similar thing. For Android there's Twilight (not the shitty book).
Lmao yeah, I was using the twilight app, which filters out certain types of light that can make it harder to go to sleep if you see them right before bed. I didn't realize it transferred to the screenshot though.
No, not at all. The way apps like Twilight work, they put an actual tint over the screen as /u/Cyp12die4 said. It's like looking through stained glass. In contrast, CF.Lumen works by actually modifying the output color of your screen. So, installing a red light bulb in a lamp, instead of a white one.
So if apps like Twilight were like using your phone with sunglasses, then CF.Lumen is like actually turning your display brightness down instead. Hope that's a good explanation.
There is some chance that an app like Twilight that uses an overlay method can damage your screen over time, if only slightly. But an app like CF.Lumen is guaranteed to have no adverse effects on your screen, just based on the way it works. That is unless you're using the "Non-root" option in CF.Lumen. Any option other than that will serve you fine, no long-term damage possible.
Easily the app I use most is Twilight.
Taken from the Google Play page:
"The Twilight app makes your device screen adapt to the time of the day. It filters the flux of blue light emitted by your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times."
Not only have I had it run in the background while working, it has a bedtime reading setting, which I use to browse reddit before passing out.
The Windows/Mac version, called f.l.u.x:
There's software available to control the light emitted by computers and smart phones, white/blue light before bed tends to distrupt normal sleep [link] [link] Of course there's also color changing light bulbs, red tends to be least sleep distruptive.
Whenever I have an app or something else where buttons aren't working it's almost always another app overlay that is interfering, in my case Twilight, the screen dimmer. I occasionally have to pause Twilight to allow specific buttons to work in other apps/browsers/etc. It's rare, but when it happens, that's always been the culprit for me.
Any chance you have another app that may have some sort of overlay interference with certain Trivia Crack buttons?
You can never go wrong with a newer Samsung. I have a Galaxy S4 and it has been great. Due for an upgrade though, thinking of the Note 5 when it's released or the Note 4 if it proves to be too expensive.
I'm not so sure about LG, I never hear anything good or bad about them. I have one of their cheap tablets and it seems to be funky sometimes. Opening a large album of images in Relay for Reddit's image preview makes Twilight crash all the time. This doesn't happen on my S4.
A lot of people like Motorola but I found the Moto X to be really annoying to use when my grandparents had them.
HTC is well praised and the M8 got some awards last year. I've never used one myself though.
It's this guy here. It acts as a screen overlay, so I find it doesn't always play nice with other apps - but I can't live without it now.
EDIT: I just upgraded to the pro version with my play credits and theirs an option to turn it on when certain app are on.
On my 4.4.4 Moto G, the window title is "Package installer"; if you have a profile checking %WIN for that value, it just might work.
For whatever it's worth, Twilight has an exception list (it's under More Settings > Auto-pause in specified apps); com.android.packageinstaller is one of the entries it currently has within the ban list in its preferences file.
There is an app in the Play Store for AndroidTV that does this. I'll try to come up with the name.
EDIT: FOUND IT. It's called Twilight ([link])
Twilight on Android, its an app that gives the screen display a reddish tint at cretian times (usually at night) to reduce the strain on you eyes.
re: blue light
Mac / Linux / iPad & iPhone links there as well
Put it on everything...
edit: including spouse's phone, who insists on blasting your face with her filthy peasant blue light while you're trying to go to sleep.
You can download an app like Twilight, it filters out the bluelight which is usually the color emitted by phones that tend to keep people awake.
For Android users, you can get an app such as Twilight (Free Version), that pretty much does the same thing as Night Light and f.lux for PC's, and filters out blue light emission.
Desde hace bastante que uso esta aplicación en el celular, la uso para que el brillo a la noche no me mate tanto la vista más que por problemas de sueño. El equivalente para PC es f.lux.
Lo que te provoca problemas para conciliar el sueño es la exposición al brillo azul (tonos fríos) que generan las pantallas y los monitores, que le hace creer a tu cuerpo que todavía es de día, mientras que los tonos cálidos (amarillentos) favorecen el sueño a la noche (como si fuéramos pajaritos) y son más cómodos para la vista. Por la misma razón es que existen las lámparas de luz cálida para dormitorios, y luz frías para el resto de los ambientes.
I've been using this on my Android and this on my laptop for months, and they both work great. It greatly reduces that glazed over feeling you eyes get and when I try and sleep I don't feel like my eyes are recovering from looking at a bright screen.
For those that suffer fatigue resulting from eye strain, I would suggest you use F.lux for your computer, or for Android the Twilight app.
I contracted a severe case of conjunctivitis a few years ago that left me essentially blinded (felt as though sharp glass particles were in my eyes as I opened them) so I was forced to remain confined to my bed for several weeks, but this persisted well over a month. I had also been experiencing high levels of fatigue and flu during this time.
I was checked by an ophthalmologist at the NHS, who prescribed me with antibiotic eye drops (after my GP prescribed me with the wrong one) and explained that it was likely caused by bacteria entering the eye. After this incident I would go on to develop several other health problems throughout the years that would indicate a compromised immune system.
If all you need is f.lux, try this: [link]
As for if its worth it to trip Knox, that's really up to you. Personally I did. You lose Samsung Pay permanently, and your warranty is void. Didn't matter much to me, so I did it anyways, but it's really up to you.
I used to have a Samsung S4 Active. Pretty to of the line model when it came out. Battery life on it sucked but it was my baby until it was stolen. Bought a temporary "budget" Samsung J2 while I wait for the Priv thinking I'll manage with an extra battery and a power bank but I'm surprised at the longevity of this tiny 2000 mAh battery. Ofcourse it's brand new but I'm still the same ole power user (I think installing the Twilight app might have helped though).
> brand new
While it's possible the recent CQ update has performance bugs, you'll also want to check your background processing. I know for a fact that this app, when it's active, causes CQ to run more slowly.
Also, I wonder what resolution CQ runs at... The S7 has a higher res screen so...
For the screens, maybe a filtering app would be of help? I guess it's the blue light that makes our brains perk up, so the theory behind the apps is that you won't get the full whammy if that's filtered out. I can't comment on it myself, since I can generally fall asleep pretty easily these days, but a couple of friends use it and say it really helps.
> Not to mention how much easier it is to fall asleep after not staring at screens.
f.lux reduces the blue light in your computer screen at night, making it easier to fall asleep.
There is also software like that for your phone! (e.g. [link] )
I highly recommend it.
I use an app called Twilight [link], it reduces eye strain at night or anywhere really. I guess the screenshot captures that as well.
If you put the alarm on your phone perhaps the blue light reduces the melatonin, I recommend using Twilight [link]
and also for the PC
I love using flux for my computer! I realized the benefits of using flux pretty soon after I started using it. I have less trouble going to sleep and I feel way more relaxed and rested!
I have also found to use something on my phone.
If you have an Android, check out Twilight. It is just like flux but for your phone and it has a lot of extra features like auto adjust time to change the color according to sunset/sunrise etc. You can also pay a small fee to unlock even more features for Pro version. I have paid for it because it is awesome but the free one also does the job very well.
