kebab_definite So what is the recommended way to download and obtain apps if google isn't an option, and it is not on Accrescent?
I believe the recommendation in that case would be to get it from where you need to. The developer's website or GitHub would be the next best option.
We cannot recommend F-Droid due to major security and trustworthiness issues. We don't recommend adding this as another trusted party instead of using developer builds
Not all developers publish their builds though. If you must have an app that is only available on F-Droid, then I guess you'll have to get it from there. But maybe consider if another app would work just as well.
You can also use App Verifier to verify the app's signature (only necessary on the initial installation - and doesn't really mitigate the risk of F-Droid, since they're signing the builds anyway).
Our own App Store, Accrescent and App Verifier are highly recommended by GrapheneOS.
