not an android user but ive heard great things about amethyst for a client. and i really like coinos for a wallet. very simple to use.

Can you zap others with Coinos?
yes. it has an LNURL and you can chose your @ name to match your user name. the only thing that isnt perfect yet is there isnt a way to add your nostr profile without giving your nsec. so it assigns you one. the client notifications for zaps go to that. but if you are using it on mobile or from an extension you will get them.
