DeadMan-Switch is an Android application focused on personal safety and emergency response automation. It continuously monitors user activity, location, and device status, triggering alerts if inactivity or danger is detected. The app integrates movement checks, battery alarms, and background location services, ensuring that the user’s well-being is tracked at all times.
Its core feature is the “dead man’s switch” mechanism: if the user fails to move or respond within a set timeout, the app automatically sends SMS or email alerts with location details to predefined contacts. Users can configure danger locations, preset help messages, and multiple contacts for automatic notifications. Manual SOS triggers are also available via power button presses or siren alarms. With silent/background modes, DeadMan-Switch operates discreetly while providing a robust safety net for individuals in risky environments.
