Damus is iOS , on every note on the app there’s a ⚡️ icon for anyone who’s set up a LNURL on their profile. In the Damus settings you can set up your default wallet of choice (in my case muun) and a default amount you want to zap people. Example 21 sats . Then when you scroll through nostr and interact with people , you can easily zap by clicking the ⚡️ icon on notes, muun opens directly and I just confirm 21 sats , done ✅
