Fernweh - Offline Messages

Connect Beyond the Grid
Fernweh is a hybrid messenger that works everywhere, online or off. Chat, call, and share files over a decentralized Bluetooth mesh network when there's no internet, and seamlessly switch to an encrypted online relay when connectivity returns. No central servers storing your data. No compromises.

How It Works:
Fernweh creates a peer-to-peer mesh network using Bluetooth and WiFi Direct between nearby devices. Messages are encrypted and relayed device-to-device until they reach their recipient. When the internet is available, an encrypted online relay extends your reach globally. Calls connect through secure signaling with end-to-end encryption. Everything is stored locally on your device, never on a central server.
