I use KDE Connect as a media remote and to transfer files between my phone and computers. It has quite a few other functions, like remote mouse control, sms, seems to share clipboards as well.

• Miniflutt: read RSS posts through my self-hosted Miniflux server
• Mullvad VPN: protecting my identity wherever I am
• OpenTracks: track my movements
• Seal: download videos from mainly YouTube, but also converting YouTube videos to MP3 files (perfect for downloading music mixes for my bicycle trips)
• Syncthing: syncing important files to and from my desktop
• Voyager: browsing Lemmy

Suggestion For OP

OP You should use Florisboard beta it’s good and also Obsidian is not open source.

Obtainium is great for updating apps hosted outside the playstore, big upside being you don’t need to bother with FDroid releases

THANK YOU for antennapod!!! What an incredibly beautiful app, I’m so impressed!!

If you use Organic Maps you may be interested in https://streetcomplete.app to help fill out the map

I’m running openboard’s fork by helium! It supports glide typing, if you download a library! There are instructions in the app 🙂

I also recently found sayboard (available on fdroid), which has been working WAY better than I expected as a speech-to-text alternative 🙂

Obsidian isn’t FOSS. I highly recommend Logseq but keep in mind they require CLA signing for contributions

Keyboard:

• AnySoftKeyboard good all around keyboard, good language support, decent though messy customizability
• Unexpected keyboard more specialized, provides easy access to app (printable) ASCII characters and some others, allrght customizability
• 8Vim Cool factor, great customizability, decent language support but you need to learn it

Games:

• Pirate Solitare nothing much but I’ve been playing it a lot lately
• Simon Tathman’s Puzzle Collection a cross platform puzzle collection, has a lot of different puzzles in a uniform style
• Antimine minesweeper with nice ui

System:

• RethinkDNS: DoH provider and firewall Easy to use, especially nice for those non FOSS apps you need to have to maintain a social life, not that powerful though
• Obtainium: FOSS app downloader Downloads apps from releases or equivalent, therefore can have faster updates than fdroid, but no discovery, aside from search on some platforms
• ffupdater: FOSS browser downloader Like obtainium, but for browsers (mostly) and has list of browsers
• Droid-ify: fdroid client better ui than the default app, comes with a list of repos
• Shizuku: ADB shell api not useful if you have root (see SUI, which is the root implementation for the same api, though shizuku will also work I think), but can give a bit more access if you don’t supports wireless debugging on A12+
• Neolauncher: launcher nice ui but nothing special
• SD Maid SE: storage cleaner okish ui, doesn’t stop me from having 302 (not including system) apps on my device. Yes I have a problem
• Package manager: app manager Shizuku support, powerful, though limited if you don’t have root
• Inure: app manager [freemium (8$), but GPL licensed?] pretty must like Package manager but with amazing ui

Media:

• LibreTube: Piped (youtube) client Nice ui, no ads, sponsor block support, kinda unstable
• Innertube: YouTube music client doesn’t use piped/invidious, no ads, nice ui
• Tusky: mastodon client nice ui, quite stable, multiuser support
• Jerboa: lemmy client ok ui, up to date with lemmy updates
• Liftoff: lemmy client nicer ui then Jerboa but doesn’t work since .15 (?) and had issues with rendering markdown properly
• LibreTorrent bitTorrent client for downloading all those isos and public domain works, nice ui

Misc:

• Mull: ff based browser not much to say, “security oriented and deblobbed”, upstreams some features from Tor
• Calculator++: A scientific calculator A lot of functionality while remaining easy to use
• RPNcalc: A Reverse Polish Notation calculator best RPN calculator I’ve found on fdroid, less powerful than Calculator++, but RPN based calculators are more efficient^[1]^
• Simple Apps: suit of apps providing basic functionality great ui and customizability, I don’t use simple keyboard, simple launcher/drawer however
• OpenCamera: a camera app advanced features

Just the apps I thought of, as I, as mentioned in the SD Maid entry, have a lot of apps installed :P

Obtainium is pretty good
