It is powerful with privacy as well, it has secret chats and it supports TOR in the settings "Use SOCKS proxy" (just install Orbot and in the settings be sure it allows background starts you don't need to have it running as VPN)
Wallets:
Depends on your technical level and how much time are you willing to spent understanding and setting them up:
1. The inpatient with no time to waste and who doesn't care to use custodial wallets:
Go for wallet of Satoshi, add it to your profile and don't do the NWC (network wallet connect) setup. When you try to zap someone, the wallet will open and the invoice will load, easy and setup free.
2. The curious one with not much technical expertise but eager to learn:
You have few options here to play with that are interesting
2.1. nostr:nprofile1qqstxwlea9ah3u6kjjszu6a7lrnhqkfh8eptp2z6v0e9558tlkkl2rgpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9mhwden5te0wfjkccte9ec8y6tdv9kzumn9wshszxnhwden5te0wfjkccte9ekkjmnfvf5hguewvdshx6p07xr4s5 (mobile app)
2.2. Sovereign App (mobile app)
Two good options, both support cashu and LN⚡, start learning about cashu, IMO a game changer for small payments. Sovereign offers novelty features I consider a must have, still in development, use at your own risk
3. The tech savvy:
3.1 GetAlby running AlbyHub
3.2 @Sovereign running your own mint with your own Clan (mind blowing)
3.3 npub.cash - get your npub followed by npub.cash and use it as your wallet address to receive LN payments and cashu payments, use AlbyGo or Phoenix for zapping
