One of the things I struggle is to discover new or popular apps, because of the lack of stats on f-droid (privacy first, I'm not complaining).
So I'm interested on the community knowledge.
For me the best ones are:
- Syncthing (device synchronization over LAN or internet without a centralized server)
- Omnivore (read it later and newsletter reader)
- Wifi Analyzer
- LocalSend (Multiplatform alternative to AirDrop)
- Proton: ProtonMail, ProtonCalendar, ProtonDrive, ProtonVPN (secure services with E2EE and full remote serve encryption of your data)
- DuckDuckGo: DDG browser, DDG Email protection, DDG app tracking protection
- Material Files
- Simple Galery Pro
- OnlyOffice (FOSS office suite)
- K-9 Mail (multi-account centralized email app)
- P!n (small notes/reminders on your notification bar)
- Termux A linux terminal for your android. Personally I use it for managing Git repositories on wich I store my personal notes
- Bitwarden Password Manager with free synchronization. Multiplatform also.
I love KISS Launcher, Cuppa (Tea Timer), ccgt (tui instrument tuner), Obtainium, Elk (a mastodon client in a Progressive Web App), and of course Jerboa for Lemmy!
