About this app

Ratspeak is a native desktop and mobile client for E2EE conversations over Reticulum, a new type of mesh networking. Ratspeak gives you messaging, file/image sharing, LoRa capability, WiFi, BLE, TCP, offline messaging, turn-based games, and more.

What It Is

Ratspeak is for private messaging when the normal internet is unavailable, untrusted, or not the path you want to depend on. When your cell tower is down, when natural disaster hits, or when you just want an alternative. When you know the current system is broken.

It runs on Reticulum and LXMF, so conversations can happen over regular internet, LoRa radios, WiFi, Bluetooth, there is no limit - if it can move data it can be a part of the mesh.

There is no Ratspeak account server, no central database, no hub where everything routes through by default. Your Reticulum identity is generated on your device and becomes your address on the mesh, no personal information needed.

What You Get

- Account-free messaging over Reticulum. - Full offline messaging support. - Local Network, TCP, RNode/LoRa support, Bluetooth Peering, and more. - Contacts, discovered peers, path requests, interface status, propagation status, and transport health in the app. - Chess and Tic-Tac-Toe. - I'm tired boss, this whole README is going to get a revamp.
