The system starts timing after the user sets a countdown timer (12/24/36 hours). Regular phone use automatically resets the timer. If the countdown reaches zero and there is no response, the cloud server sends a notification to emergency contacts, including the last known location. Because the alarm is sent from the server, the notification will still be delivered even if the phone is damaged, out of power, or turned off.
Key features include: Stealth Mode (silences the phone during alarms), Guardian Password (prevents others from disabling the system), Low Battery Notification (sends a distress signal when battery is below 5%), Daily Reminder (reminds you to activate the system at a fixed time), and Guardian Angel Mode (disguises the interface as a game, hiding the distress signal).
The free version provides basic functionality; a paid subscription provides cloud credits to activate the cloud-based system.
Requires Android 8.0 or higher, internet connection, and location and notification permissions.
