What is Mesh Messenger Offline?

Mesh Messenger Offline is a decentralised, peer-to-peer messaging application that works entirely without an internet connection. Using Bluetooth and WiFi Direct mesh networking, it creates an ad-hoc communication network between nearby devices.

The problem we solved

Internet-dependent communication fails exactly when you need it most — natural disasters, remote locations, network outages and high-density events. Mesh Messenger fills this gap with resilient offline-first communication.
