et pour Android
I'm not aware of a total limit for free accounts. You need to accept the nsec.app connection request. If you're on iOS, there's special instructions https://nsec.app/ios.html. It's much easier to use a nip-07 extension though. I use nostr:npub1tnpfz60snm7ler8k8c69335n37we6690qttl88t556yzkjxhahjq3kkkpe on iOS.

https://nsec.app should work, but I haven’t tested
