About this app

This is ad free (no ads) version of

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

Functional app that does what it says. Could really use an update (it's been almost 5 years since the last one). Every time I open it I receive a warning from my system saying that the app is for an older version of Android and may cause problems with my phone because it's written for a much older version of the operating system. So it makes me wary of continuing to use it.

I use this app to help me detect/predict motor bearing failures. It is not a precision instrument but when used frequently one can understand what the readings indicate. Absolutely great to determine which bearings are failing when used on aa electric motor or pump.

This is not 2001, you should be able to run any app in landscape orientation. This is just one more portrait only flip phone apps
