F-Droid

• Termux (or equivalent) has always been the primary mobile phone use case for me. Access to my main computing platforms from my pocket.
• Antennapod
• Fedilab (Mastodon)
• Fennec - Can't deal with the web without uBo and other extensions.

• KDE Connect
• IronFox: fork/successor to the defunct Mull browser
• OSMAnd~
• AntennaPod
• Transistor: for internet radio
• Any music app, they're all good; I'm currently using Symphony
• Jerboa: for Lemmy

Pipepipe - newpipe fork with sponsorblock and Google account fallback for restricted videos

Quillpad - Google Keep replacement

KeepassDX - password manager and nice keyboard that autotypes what you want without copy pasting

Syncthing-fork - for syncing files

• Fennec

Sorted them into a few categories

Social

• Cheogram - xmpp chat, can also handle phone and sms gateways

• Fedilab - my preferred fediverse app for mastodon

• Jerboa - preferred lemmy app

• K-9 Mail - email

• Pixelix - pixelfed app. not sure if I like this or PixelDroid better yet

Media

• AntennaPod - podcasts

• Kiwix - offline copies of useful wikis, q&as, archives, etc.

• Librera FD - books

• NewPipe - watch youtube videos, although google keeps trying to break it

• Voice - audiobooks

Security

• Aegis - two factor authentication

• KeePassDX - password management

• WG Tunnel - VPN connection, still not sure if this is the best option

Notes and Documents

• Orgzly Revised - note taking. for people not familiar with emacs something like logseq or safe notes might be better

• Pinkt - bookmarks

• Syncthing-Fork - synchronize files between devices

System

• F-Droid - technically it can install itself

• Lawnchair - alternative home screen / app launcher

• ntfy - runs in the background, handles push notifications for some other apps

• Unexpected Keyboard - has the fancy keys that most android keyboards leave out

Other Tools

• Fennec - basically firefox

• Organic Maps - sometimes missing info and it doesn't have traffic data. simpler than OsmAnd

• PocketPaint - make art on your phone

• QuickDict - offline multi-language dictionary

I've got hundreds more installed, but those are some of my favorites.
