Not sure about the rest of those, but Obsidian isn’t OS either.

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

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.

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

Catima - for saving arbitrary barcodes and stuff that are hard to integrate into other wallets. I keep my local library card in there, and it works wonderfully

Nonocross - fun little game that has zero frills and distractions. Also very responsive on their github to suggestions and improvements

Termux - when I need to get into things from afar, this is how I do it

Box, Box! - Formula 1 news, schedules, standings, etc

Coffee - Sometimes I want to keep the display awake, so this comes in handy

I am lazy, so let me just put the link to my non-root smartphone guide with a section for FOSS Android apps.

Openboard (though seems dead and looking for alternative)
Internxt

Obsidian is Open Source? I switched to Logseq because it wasnt open source. A friend wasnt even allowed to install it on his Work PC becauze Obsidian wants 50€ per Year when not used at home privately.

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 🙂

• Acode - code editor
• Auto-Auto-Rotate - remember rotation lock settings by app
• Auxio - there’s a million music players, this one scratches my itch just right
• Binary Eye - bar/QR scanner
• BreezyWeather - appears to have sources globally
• Collabora Office - view & edit libre/Microsoft office files
• Missed Notifications Reminder - I need a repeating audio notification so I don’t miss important work related messages
• MJpdf - pdf reader
• Mull - privacy enhanced Firefox
• RoMote - roku remote on your phone
• Skymap - what is that thing in the sky?
• Snapdrop - share with other devices via snapdrop.net (crashy) or pairdrop.net (better)
