You can learn more about why we migrated Fountain's social features to Nostr in the following episode with @MerryOscar and @nvk.

What do you mean by "Android Signer" and there's a bug in your app when I try using a Nostr private key extension.
Android Remote Signers like Amber let you sign remotely on mobile from a single app - https://github.com/nostr-protocol/nips/blob/master/55.md
What went wrong with the web extension exactly?
Can I do social functions as a nym? Or do I HAVE to use Nostr?
You have to use nostr to use the social features in Fountain - but you can create a new nostr profile in the app if you don't want to use your main nostr profile. You can also choose whether or not to share to nostr each time you boost or comment.
