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.
