Welcome to the RB family, MBCompass 🥳
apt.izzysoft.de/packages/com.m…
MBCompass is a simple, reliable compass app with a sleek design and accurate navigation.
Thanks to Mubarak Basha, its developer, for making this possible! 
This brings us to a new milestone: also welcome the "3rd egg" 🐣
RB status: 410 apps (33.3%)
Meaning: each 3rd app, 1 out of 3, at IzzyOnDroid is now covered by RB 🥳
IzzyOnDroid ✅
Unknown parent • • •@leo this is what proves that the APK was indeed built from the very same source it claims. Cross-updates are possible when the same signing key was used in those places – which implies that the app must be set up for RB at F-Droid as well, as otherwise F-Droid uses a key they generated (and then, cross-updates are not possible).
Signing ensures that updates are only accepted when the same key was used, where only the owner knows the credentials for.
IzzyOnDroid ✅
Unknown parent • • •@leo It's not cross-signing; those entries with identical signatures are signed by the same key (here, the one of the NewPipe team & signed by them, so same APK).
For NewPipe, I'd recommend installing it from their repo, for faster updates (YT breaks its own stuff frequently, in effect breaking the app; their own repo is where the adjusted APK will show up first; F-Droid's repo usually takes 2..5 days longer; IzzyOnDroid just a few hours, so that would be fine as well, depending on your needs).
