Curious why you don't use Zapstore. It's a great way to get nostr apps and be confident the release is signed by the dev.

Comfort thing
I get that. We do have some devs who are very much against the official Google PlayStore (for good reason), which means you simply may never be able to use their apps unless you are willing to step outside of that comfort zone and either use the Zapstore, or download the apk directly from their GitHub.
