What I liked about 0xchat:
-Handy chats in UI.
-In config, possible to use only onion hosts.
-Private notification push.
-Some trickery like not being able to screenshot.
What I didn't like:
-I don't see timelines unless I tap individually each user, big con.
-It's not in F-Droid but in the Play Store.
What I like about Amethyst:
-UI allows to basically see everything, big pro.
-It also allows to use Tor.
-It's in F-Droid.
-More features.
What I didn't like:
-I can't force Tor only onion hosts.
-Google Firebase notifications violate privacy, although they're deactivated by default.
-Can't use bunker id?
