Zap Android

Native android lightning wallet for node operators focused on user experience and ease of use ⚡️

Zap Android is not a classical wallet, it is actually a remote control for one or more of your LND Nodes. Zap Android aims to give node operators the opportunity to use their node in everyday situations with a simple and appealing user interface.

The easiest way to get started is using Umbrel to run LND on a raspberry pi and then connect Zap Android to that node.
