What are your favorite Android FOSS applications

The Simple Mobile Tools suite by Tibor Kaputa is excellent. They're all FOSS and "simple" without compromising on features. The "Pro" versions are also open source and available for free via F-Droid.

AntennaPod is an excellent podcast app.

Syncthing-Fork is superb for file sync.

KeepassDX is an awesome password manager

Signal and Element are open-source messaging apps

RedReader and Slide are awesome Reddit clients

OpenBoard is a clean, simple, privacy respecting keyboard.

Notally is a simple notes/to-do app that can replace the likes of Google Keep and Simplenotes.

StandardNotes is a superb end-to-end encrypted note-taking app.

Joplin is another excellent full-featured Markdown note-taking app that is offline by default but lets you use e2ee sync over Dropbox or other cloud providers.

OctoDroid - for Github Slide for Reddit Kiss launcher - text based launcher Librera Pro - best eBook reader (with tts) Antennapod - best podcast app Termux - Linux terminal with super powers LibGen Mobile - Sci-hub and more Syncthing-fork - file sync that works

All are in F-Droid

Minetest, Shattered Pixel Dungeon, Loop Habit Tracker. But now I'm on Mobian :)

Most of the stuff I run via Termux is open-source.

(FWIW, Termux on an Amazon Kindle Fire HD 10 is really nice; I got mine via on sale for about $100.)
