Aegis Authenticator, AntennaPod, Aurora Store, Auxio, Bitwarden, Exodus, Forecastie, Fossify Contacts, Fossify Phone, Fossify File Manager, Fossify Gallery or Immich if self hosting pictures, Gmaps WV, Hypatria, Jellyfin client if self hosting media, Kvaesitso, Libre Camera, LocalSend, Mull, New Pipe, OpenBoard, OpenCalc, OsmAnd~, Pedometer, QKSMS, RHVoice, RustDesk, Send Reduced, Simply Translate Mobile, Tailscale, TrackerControl, VLC, WifiAnalyzer.
