Most earthquake apps only track tremors. Deprem Hub is designed to keep you alive when the grid goes down. It features a Bluetooth Rescue Radar that turns your phone into a beacon detectable under rubble without internet. Includes an Offline Survival Whistle, a Personal Seismograph, and an "I'm Safe" SMS Protocol for when data networks fail. Your phone is your lifeline; make it visible to rescuers.
