I know this thread is already a little old, but here is the list of my favorite apps from F-Droid/Izzy. I use a lot of these almost daily and just thought I would share these in case someone might find a new app they find useful
Eternity (Infinity for Lemmy)
Buckwheat (Budgeting)
Aegis (Authentication)
Lawnchair (Pixel-like launcher)
Quillnotes (Markdown notes app)
Forkyz (Crosswords)
Geometric Weather
Imagepipe (Removes exif data and reduces pics)
AntennaPod (Podcast app)
Olauncher (Beautiful and minimal text based launcher)
Thank you
