The Best Vibration Meter

Best Vibration Meter is a free app which can measure the vibration (seismograph, body tremor, seismometer).
This app uses the phone sensors to measure vibration or the earthquake, and it shows a reference as a seismic detector. Using Best Vibration Meter, you can check vibrations on the modified Mercalli intensity scale.
You can calibrate your app so that the maximum value is about 10-11.
Best Vibration Meter shows reference to earthquake vibrations as classified by internationally used Mercalli intensity scale for seismic activities such as earthquakes. The Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake. Vibration Meter can also be called seismograph or seismometer when used for measuring seismic activity.
