This is a simple utility app which will vibrate your phone, in order for you to test the vibration functionality of your device. If you're having issues with your phone not vibrating when it should, you can run this app to see if the issue is with the vibrator or a different aspect of your phone (helping you to narrow down the issue).

There are three options:
- Vibrate for 0.1 second
- Vibrate for 1 second
- Vibrate for 10 seconds

There's a progress bar indicating the timing of the vibration.
