Quiet confidenceA simple boundary.
A simple boundary.
A powerful response.
Built for moments when your attention is elsewhere—but your device still needs a dependable layer of protection.
02
Know when it’s crossed
A persistent, full-volume alarm and vibration respond when the boundary is breached.
03
Keep control secure
Biometrics or your device credential guard activation, deactivation, and alarm stopping.
04
Keep location private
Your location and geo-fence settings stay on your Android device—not on our servers.
How it works
Protected in three deliberate steps.
No complicated setup. Just choose your boundary, authenticate, and let the background service watch the perimeter.
1
Choose your radius
Set a boundary between 10 and 500 metres.
2
Securely activate
Confirm with biometrics, PIN, pattern, or password.
3
Move with confidence
The app monitors in the background and alerts on a breach.
Privacy is the architecture
Your location belongs to you.
GeoFence Guardian performs its location checks locally. Your coordinates are not sent to an external server, and biometric verification is handled by Android’s secure system APIs.
- ✓ Local location processing
- ✓ System-managed authentication
