Many thanks OP for starting this thread and also big thank you to all suggesting Mull
and Mulch
. I was not aware of those apps and will try out both of them.
Here are some links to start from:
- DivestOS website with information about their apps: https://divestos.org/pages/our_apps
Mull
directly from F-Droid: https://f-droid.org/en/packages/us.spotco.fennec_dos/Mulch
only from DivestOS F-Droid Repo: https://f-droid.org/en/packages/us.spotco.mulch/ - must enable repo first!
Your question reminded my immediately about one of my favorite 35c3 talks Butterbrotdosen-Smartphone - Mein DIY-Smartphone-Bau from 2018-12-29. It is in German language, but has an English translation, too. Maybe it can give you some good starting ideas?
