Vibration Alarm is a powerful vibration meter tool for Android devices that features real-time vibration monitoring and the ability to save vibration data to the SD card. It also includes a configurable sound alarm that can be used to detect earthquakes or when someone opens a door while you sleep.

It is recommended to use the battery charger when using the application for an extended period of time. However, it should be noted that there is a known issue with some devices where the vibration sensor does not provide data when the screen is off, due to an Android error. The developer is actively working on finding a workaround for this issue.

Overall, Vibration Alarm is a useful tool for those who need to monitor vibrations in real-time and want to save data for future analysis. It is important to note that the application comes with absolutely no warranty. If you experience any issues with the application, the developer encourages users to send them information for troubleshooting purposes.
