Crisis Comm — off-grid communication via BLE
A mobile app, built in React Native, that lets loved ones stay in touch during emergencies when the network goes down — from power outages to conflict zones. The app works entirely offline over Bluetooth Low Energy, paired with a proprietary IoT BLE extender based on ESP32: a small device with a 10 m data cable that you place at the front door while you carry the other part with you — bridging concrete walls or basements that normally block the signal.
