Minibits, connected to Amethyst via NWC. My device does not need to be online to receive zaps, as it is handled by the Cashu mint's Lightning infrastructure. 

 Can this be done with an iPhone and damus? 

 Minibits is Android only. However, Damus supports Nostr Wallet Connect (NWC), so it can be connected to an IPhone compatible Cashu wallet such as eNuts. https://enuts.cash/ 

 My man thank you! 

 Most welcome.
