I didn’t try with primal because of the email requirements, can recommend nostr:npub1hcwcj72tlyk7thtyc8nq763vwrq5p2avnyeyrrlwxrzuvdl7j3usj4h9rq, or nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv (currently in TestFlight, checkout minibits.cash). The latter works well with NWC too. Both are simple to set up compared to many I’ve tried. Zapping is smooth with nostr:npub1kvaln6tm0re4d99q9e4ma788wpvnw0jzkz595cljtfgwhldd75xsj9tkzv and the NWC setup.
