Yes totally agree this isn't ideal. On Android we support NIP-55 remote signers like Amber. On iOS we plan to add NIP-46 remote signer support - the only reason we haven't yet is there isn't really a great mobile NIP-46 signer for iOS. I'm actually hoping that @Damus or @primal might add NIP-46 remote signing capabilities - would make onboarding easier as 1 less app to download.
