Might be helpful to f-droid users to know what others are installing so here’s some of mine.
Fedilab to browse mastodon, find it’s long press options really convenient for accounts across multiple instances. You can also use it for stuff like friendica but I find that awkward since it’s still using a UI meant for twitter-likes.
NewPipe to stream youtube.
AntennaPod to subscribe and listen to podcasts
VLC, the Swiss army knife of media playback. Can play pretty much any local file and supports streaming(IPTV and the like) via m3u files.
Librera PRO for epubs, PDF, cbz ect
AnySoftKeyboard virtual keyboard/ime with suggestions
Aurora Store to update webview
G-Droid an f-droid client with a UI I like and it supports reviews via a mastodon account.
KDE Connect for various linux desktop integration things
Lawnchair is what I use as my home screen app
Material Files file manager, find it to be more stable than amaze and it can extract several varieties of tar.* files as well as compressing 7z/tar.xz/zip.
Termux terminal emulator with packages
Shattered Pixel Dungeon fun roguelike with cute graphics.
Frozen Bubble puzzle bubble like game with multiplayer support.
F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.
