shows reference to earthquake vibrations as classified by Mercalli intensity scale.
Vibrations are shown in all directions: X, Y, Z in different colors.
Place your device on stable surface and measure vibrations.
Mercalli intensity scale
I. Instrumental - Not felt. Recorded by seismographs.
II. Weak - Rarely felt, usually only on top floors of high buildings.
III. Slight - Felt indoors, like a passing light truck.
IV. Moderate - Windows, dishes, doors rattle. Like passing train.
V. Rather Strong - Felt by all. Small objects upset.
VI. Strong - Books off shelves. Trees shake. Isolated damage.
VII. Very Strong - Difficult to stand. Many poor buildings damaged.
VIII. Destructive - Significant damage. Branches broken from trees.
IX. Violent - General panic. Serious damage. Ground cracking.
X. Intense - Most buildings destroyed. Rails bent slightly.
XI. Extreme - Rails bent greatly. Pipelines destroyed.
XII. Catastrophic - Near total damage. Objects thrown into the air.
This app uses the phone sensors to measure vibration or the earthquake, and it shows a reference as a seismic detector.
You can calibrate your app so that the maximum value is about 10-11.
Check the vibrations with you phone!
For example, it can be used
• To measure the acceleration of a vehicle.
• To measure the vibrations caused by a vehicle (indicates the comfort level of this vehicle).
• To measure the inclination of a surface.
• As a quick assessment tool to measure how intense are the vibrations produced by a product you are going to buy.
• In any other professional or even fun usages you can think of.
• Time Domain Analysis
Shows the magnitude of vibrations or the acceleration over time.
• Frequency Domain Analysis
Displays a graph showing the measured frequencies on the X-axis and the magnitudes of each frequency on the Y-axis.
• Time Domain Parameters (Advanced)
Calculate features of the acquired vibration samples (Minimum, Maximum, Average, RMS, Variance, Skewness, and Kurtosis).
• Analysis can be done on the X,Y, and Z directions.
• Save snapshot of current analysis graph.
For any feedback, bug reports, or required features, please send an email at email@example.com.
Strobe Light and Flashlight
- Strobe your device's screen and/or flash LED from 1 - 30 Hz. Strobing helps one to see objects vibrating too fast for the eye to see.
- Turn your device's screen and/or flash LED into a flashlight; this makes a conveinient flashlight during test setups.
- NOTE: Not all device's LED flash can be controlled by the VR Mobile app.
- Remotely control VibrationVIEW from within the VR Mobile App (while on the same network).
- Start/Stop tests
- View graphs
- Adjust amplitude and frequency
Max Acceleration Calculator:
- Calculate the maximum amount of acceleration that a shaker (from a database or user input) can output based on the mass added to the system.
- Convert Acceleration, Force, and Mass units to and from common units.
- Based on sinusoidal motion, calculate Acceleration, Frequency, Velocity, and Displacement by inputting any two of these values.
- Pick between two impact types: Plastic or Elastic, and the pulse type. Shock Calculator will find the remaining two values given two inputs: Acceleration, Impact Time, Velocity Change, and Height Change.
- Measure minimum, current, and maximum dB from your mobile device's microphone. Note: A device must have a microphone in order to use this feature.
- Measure minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes.
- Zero out acceleration to calibrate for an uneven surface.
- See Vibration Research's building on Google Maps (or any other map application installed on your mobile device).
- Call, fax, or email VR directly from the app.
- Watch YouTube videos from VR.
- Visit VR's website.
- View VR's 9500 Revolution Vibration Test Controller, and the ObserVR portable DAQ.

Then this is the app for you !!!
At disposal you get two unique features:
1) A reminder that you forgot the phone if you leave it;
2) Search for the phone in case you forget where you put it.
In the first case, the clock will display the message and vibration signal, and the phone will play music.
In the second case, after clicking on the clock "Find Phone" button, the phone turn on screen with a bright shimmer and sparkle with music.
Now, using our app, you will never lose your phone!)
For using this app, you need:
1) Connect watch to device
2) Install app from Google Play
After this, app is work. If you lose your phone and go out from it about 30-50 meters, app will play music.
Also, you can find app on your watch (apps list) and open it.
