iPhone
Anti-theft motion alarm. Place phone on bag, arm it, and a continuous vibration fires the moment anyone touches it. Adjustable sensitivity and delay timer.
Motion Alarm turns your iPhone into a simple, effective anti-theft guard. Place your phone on top of a bag, suitcase, or laptop, arm the alarm, and the moment anyone touches it, a continuous vibration alarm fires — loud enough to scare off opportunists.
Adjust the sensitivity to suit the surface (low for a stable table, high for a soft bag), set a delay timer to walk away in peace, and review every motion event with a timestamp. Disarm with a tap when you return.
Key Features:
- Sensitive accelerometer-based motion detection
- Continuous vibration alarm on trigger
- Adjustable sensitivity threshold
- Customizable arm-delay countdown
- Armed / disarmed / alert status indicator
- Motion event log with magnitudes and timestamps
- Live motion-intensity display
- Clean, focused arm/disarm UX
Perfect for cafés, libraries, airports, gyms, dorms, or any time you need to step away from your stuff for a moment. Make your bag annoying to mess with.
