A few months ago I created a repo on GitLab to highlight several FLOSS apps for Android.
F-Droid is working hard to provide as many FLOSS apps as they can but I thought it could be interesting to also have a place to get free/libre and/or open source apps.
Here is the repo: List of Free / Libre and Open Source apps for Android
Hope you’ll find it useful.
I try to update it every (2) week(s).
