This app uses the device's sensors to measure unusual vibrations and at the same time trigger an alarm.

This app can be used for multiple alarm purposes when detecting earthquake vibrations or as an anti-theft mode.

Once activated, the app will sound a loud alarm and simultaneously vibrate the device to alert the user when an unusual vibration is first detected.

This is a demo version with some limited features.
