BitBanana

⚡️ Superpowers for you and your bitcoin lightning node! Use and manage your node wherever you are. ⚡️

BitBanana is a native android app for node operators focused on user experience and ease of use. While it is not a wallet on its own, BitBanana works like a remote control allowing you to use your node as a wallet wherever you go.
The app is designed with an educational approach, providing the user with guidance on every aspect of node operation.

BitBanana forked from Zap Android. You can find more information about this on the Rebranding page.

Getting started

The easiest way to get started is using Start9 or Umbrel to run LND or Core Lightning on a raspberry pi and then connect BitBanana to that node. There are of course a lot more possible ways to run a node, so please refer to the setup section in the Wiki if you need help to get started.
