Jack!
May I suggest that NOSTR needs a bounty for an Android alternative to using Google Play to download self-custody wallets.
Every one we download is recorded by the worst abuser of personal information in the world, Google.

GrapheneOS plus Aurora store gives you an anonymous session to download apps. Google play services (if installed) can be completely neutered with zero privileges & no internet access. Apps that require it will run, but nothing goes to google.
Or @ZEUS it a selfcustody lightning wallet is more your speed. Can download the APK or through fdroid
