All of these list are great as we discover new apps each time.

But, I would suggest to write what is the app about.

• Moshidon: letting me communicate with people on Mastodon
• QKSMS: text message (SMS) app

• FairEmail: an email client with tons of options
• Mull: a fork of Firefox
• Privacy Browser: a browser based on WebView
• Simple Calendar Pro: for managing my self-hosted CalDAV (waiting for Fossify’s version)
• Fossify Gallery: managing my images and videos
• AntennaPod: listening to podcasts
• Bitwarden: managing my self-hosted vaultwarden

• Foxy Droid: making browsing apps on mainly F-Droid and IzzyOnDroid like old-school Google Play Store
• Loop Habits: logging my habits
• Hypatia: protecting my smartphone from malware using ClamAV
• Lemuroid: able to play my childhood favourite games wherever I am
• 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
• URL Radio: listening to manually added radio stations
• Tasks: reminding me to do stuff
• Unexpected Keyboard: by far the best keyboard with really good shortcuts

• LibreTube: exploring YouTube through Piped API
• Simple Voice Recorder: letting me record stuff when I don’t have my audio recorder with me (waiting for Fossify’s version)

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.

• FluffyChat
• Seeker
• Pano Scrobbler
• Mull
• Orbot

• LibreTube
• Aegis
• OpenLauncher

• Prepaid Balance
• QKSMS, though it’s pretty low maintenance
• EasyNoise

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

I use Feeder for RSS. Quite a good, constantly improving app. :)

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

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)

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

Great lists so far. I’ll add one that I picked up from a previous thread:

URLCheck

URLCheck acts as an amazingly customizable and powerful intermediary when opening url links, allowing, among other things: to remove trackers, affiliate links, unnecessary elements, check Hosts, facilitating link holding and sharing, protecting against certain phishing techniques and many more…
