I'm new to GrapheneOS, just bought a Pixel7 Pro, and installed GrapheneOS; went pretty well. I'm a little confused on how to install apps. I tried the Aurora Store, but the search never seems to work; always returns "Opps, This account is rate limited!" I understand that F-Droid should be avoided in general (something about it's release model), but tried it anyway. It's search works, but it can't find most of the apps I'm looking for. Tried Obtainium; it works great, but seems to be limited to open source.
I'm hoping to avoid google and the play store in general, but haven't figured out how to do that. Every app seems to point me to the same place. But wait, GrapheneOS is sandboxed, is it necessary to do that? Maybe it's OK to install via play store? Or, maybe I should contact the people who created the app and request a APK? Or, ???
Any guidance would be greatly appreciated.
