Currently testing out thunder (Android) and it’s pretty sleek, especially for a side/hobby project.
Much prefer it to Jerboa, though it has quite a few less features.
Going to try out Liftoff later.
Edit: Okay, Liftoff is pretty impressive, but some accessibility issues and certain things are finicky.
I’d try memmy, but it looks like I’d have to build it from source for Android (I don’t see an APK in their GitHub releases) and I’m far too tired to do that. It’d be great if it hit F-Droid soon.
So far, Jerboa’s been the most “feature rich”, but some of the bugs are very annoying. Don’t want to try anything not FOSS, so Connect is out for me.
