Sorry, I didn’t look closely.
I just saw Nostr and Primal and thought most of them are Primal alternatives.
But of course I know some of them (like Fountain - my podcast is obviously on there - cashu and zap.store). Other one I don’t know, and can’t use, like Amethyst and Wavlake, because they are both not on iOS.
You use Android I guess?! 

 I use Android, yes. Wavlake is on iOS 😉 Check out Nostur on iOS. It's very, powerful and has a lot of options like Amethyst does on Android. We should try to not be married to just one client. Good luck on your journey! 

 I think it’s not on the German App Store. At least I can’t find it here.
Thanks, Nostur I know. I am using primarily Primal, Nostur and Nos and pretty happy with this combo. 

 Just saw it’s on TestFlight. Will try the beta, thanks!
