You can zap from internet browser but not sure what you mean.

I also suggest Nostore from AppStore which function similar to alby in computers so you can avoid entering your private key to other clients and sign through Nostore.

I’m currently trying snort.social with Safari+Nostore and it works pretty fine. I even (sadly) deleted Damus to see if I can survive through my Nostr journey without it on my phone. There might be other clients that also work fine with Safari but I didn’t check others yet.
