WORKS IN THE BACKGROUND:
AnchorWard uses a persistent foreground service and heartbeat system to keep monitoring active even when your screen is off or the app is in the background. Designed for reliability — if the app is unexpectedly closed during monitoring, a watchdog alert notifies you immediately.

SAFETY FIRST:
- Fail-safe alarm logic: when in doubt, the alarm triggers
- GPS signal quality monitoring with low/critical alerts
- Battery monitoring with warnings
- Multiple alarm fallbacks: local sound + vibration + notification + remote channels
- Works entirely offline — no internet required for core monitoring
