What is Reddit's opinion of Twidere?

From 3.5 billion Reddit comments

Twidere can show you combined Masto/birdsite timeline.

Twitter is a proprietary service with restricted API so it's hard to do what you want inside Mastodon.

Twidere and Twidere X are both on F-Droid. Twidere X is the newer version they are working on. Twidere has more setting options though.

Trying to move away from my dependence on Google. My phone is running GApps but my tablet is only open source software.

Got F-Droid running and there are a lot of awesome applications there.

Twidere is highly recommended.

Anyone know how to implement gesture typing without the play store?

Twidere x is a beta, if you would like to help the devs you can test it but i recommend Twidere because it's the official one and might be more refined 'cause it's more popular. You can find more about the beta here

I cannot recall where I saw the Facebook mod but follow these links for Twitter and Discord

Not sure how you define a modded app but these are alternatives. Hope they match your needs.

I do know know Fenix, but if you are looking for a highly customizeable open source Twitter client, you can have a look at Twidere (PlayStore/Fdroid)

What about open source twidere for android? Even if it's without trackers I prefer to restrict app's rights via XPrivacy. Also I prefer to change IP and block adds and trackers domains in hosts file.

I don't use any extensions- you might have to change the keys while setting an account up for the first time, I can't remember. There's a straightforward guide floating around somewhere.

EDIT: Here we go. Official keys.
