EchoBeacon: Offline Mesh Radar

When cellular towers fail, mountain canyons block satellite signals, or underground tunnels plunge you into complete digital darkness — standard maps and messaging apps become useless. How do you find your separated teammates, family, or squad members? EchoBeacon is engineered specifically for extreme wilderness, underground exploration, disaster response, and crowd-heavy environments. It requires ZERO cellular reception, ZERO internet connection, and ZERO SIM cards. By harnessing the full uncompromised power of your iPhone’s hardware — Apple U1/U2 Ultra-Wideband (UWB) spatial chips, Bluetooth 5.3 Low Energy, micro-acoustic sonar ranging, high-precision barometers, and 6-axis inertial motion sensors — EchoBeacon creates a self-contained, peer-to-peer radio mesh radar right through the air! 【6 CORE TACTICAL MISSION MODULES】 1.
