    Peer-to-peer messaging with no internet, no servers and no SIM

    An offline-first messenger built on a self-healing Bluetooth Low Energy mesh of ordinary phones. Every device is a relay: messages hop device to device until they reach their recipient. Native BLE on both platforms is bridged into Flutter through Pigeon-generated platform channels, and the whole design is documented down to a written threat model.
