What's the #nostr set up with the least friction to onboard people so they are able to zap?

nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg I believe have their Primal wallet closed to new users.

nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm I believe funnel you to their Hub and is now a paid service only? Please correct me if I'm wrong. 

Just trying to find a way I can take someone's phone and set them up, send them some sats and let them zap away in under 5 mins.
