Same for me. It runs on my Android 7.1. For the two others it has too less performance, I guess. Foxy Droid runs very stable. :D
Yes, it could be. On F-Droid is a bit more “strict” way to publish an app than on Izzy’s repo.
F-Droid supports multiple architectures. See Fennec F-Droid where combining these architectures to one APK is not able. But if that’s used, our bot can’t auto-update apps…
For more questions, just ask :D
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.
dvd is in my opinion the best mobile client for youtube-dl (are there any others?)
The repo of Izzy uses the APKs of the app authors (often the GitHub Releases). The main repo of F-Droid is built from source code. So Izzy gets faster updates, but the main repo builds from source code. Of course, the app must be open source in both.
There is also another list of repos: https://codeberg.org/mondstern/F-Droid-Paketquellen/wiki
