Primal has no ( real) kyc but is tighted to an commercial provider, so metadata is may an point.

If u're not in paranoid private mode I would recommend it for ur friends on iPhone.

Everything else has an ( to be fair a small) learning curve for integrating a wallet with nwc, Alby, etc.

So, connect with coinos/Alby over nwc isn't a rocket 🚀 science 🧪
