Well, I'm not sure the Damus project is mine to change. That said, Cypher Stack, the people behind Stack Wallet, are in the design stages of a cross platform Nostr client (Android, iOS, Desktop, like SW) using Flutter.

You can bet we're trying to improve on the current pain points of Nostr.

Happy to take some donations for our client though. Although, admittedly, we're very early design stages still.
