About this app

Vibration Meter measures vibrations using your device’s sensors on all 3 axes: X, Y, Z and 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.

Vibrations are shown in all 3 directions: X, Y, Z in different colors and specific directions can be turned off or on for more accurate directional readings.

To use; place your device on stable surface and measure seismic or other vibrations.

Mercalli intensity scale:

I. Instrumental - Not felt. Recorded by seismographs.
II. Weak - Felt only on top floors of high buildings.
III. Slight - Felt indoors, like a passing light truck.
IV. Moderate - Windows, doors rattle. Like passing train.
V. Rather Strong - Felt by all. Small objects upset.
VI. Strong - Books off shelves. Trees shake. Damage.
VII. Very Strong - Difficult to stand. Buildings damaged.
VIII. Destructive - Significant damage. Trees broken.
IX. Violent - General panic. Serious damage. Cracks.
X. Intense - Most buildings destroyed. Rails bent.
XI. Extreme - Rails bent greatly. Pipelines destroyed.
XII. Catastrophic - Near total damage.


Some countries use Richter scale instead of Mercalli scale. The Richter scale is a base-10 logarithmic scale, which defines magnitude as the logarithm of the ratio of the amplitude of the seismic waves to an arbitrary, minor amplitude.

To translate from Richter Scale to Mercalli and vice versa see below comparison:

Richter Scale = Mercalli equivalent
<3.5 = I
3.5 = II
4.2 = III
4.5 = IV
4.8 = V
5.4 = VI
6.1 = VII
6.5 = VIII
6.9 = IX
7.3 = X
8.1 = XI
> 8.1 = XII

Ratings and reviews

Does what it says & seems to be bug free. Here are some recommended improvements. The scale is faint & difficult to read. Also, the scale only goes to 2, but the scale description goes to 7. The timeline goes a little too fast. I would pay for a version that auto-scales & logs data for later review & download. I'd also like ability to calibrate.

I just downloaded the app. It can pick up vibration of me walking. Going to test it tonight to see if it can pickup vibrations i feel with my feet from the ground. If it does i will upgrade the stars since it only happens at night time. One thing i don't like are the adds on the bottom since it covers the X Y Z and some other thing i am not sure what it is half way up from the bottom.

Very good app. It works. I can see why its one of your babies. I can tell you put alot of time in it. It dos what its built for. I put my phone on the floor. I know it could pick it up on the bed but could it pick anything on the foor? Yes small singels letting me know the floor was shaking. Very cool i will be keeping thison my phone for along time. Keep up the good work.😀👍
