Vibration Meter
Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks. Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis.
Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x
- and y
- axes parallel to the surface.
Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude.Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake.In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world.
Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage:
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.
This app allows you monitor and share the results of your measurements with other users.
Measure and monitor all vibration and shocks using smartphone or tablet!

A really beautiful and utility app! Even when you are not in a seismic zone! Sensitivity is top notch is Samsung's flagship phones. Registers even slight vibrations! I even use it as an antitheft alarm when am in office or napping in public transport 😁
So much easier than using a standard triaxial, using it for assessing power tool HAV. Would like it to calculate RMS but being able to isolate x y z and saving a sample is still a huge jump! Limited to about 13 m s^2.any axis so won't work for some tools.
Great app, works well for its purpose. Would it be possible to add an option to set a custom sample rate for the data? If you can, I'll happily give 5 stars :)
I'm not sure about calibration But it's not as important as the fact that I can see different readings in different situations I've tried several of this type of app and I like this one best so far
Couldn't detect anything until I started drumming quote vigorously on the surface, which it described as "only detectable by certain people". And then it seized control of my phone to display an ad and I immediately force quit and uninstalled.
Why does the SOS not work properly when the Emergency sound is turned on, vibration then the flashlight even if it is steady there is no intensity, it is noisy and still vibrates. Please Help...
Very sensitive to vibrations, but background working mode is not perfect, app falls asleep when my phone is locked longer so there is no background activity and warning sounds if earthquake strikes
Please allow multiple select in history for export or deletion. Auto rename the exported files, not overwrite the same one.
Not sure why, but my phones security detected the app using my camera. Don't really see a need for that since the app is supposed to be using the accelerometer.
Literally vibrating the table the phone is on and it still reads nothing. I have to wham on the phone to get the meter to deflect. Or pick it up and shake it.
Too useful. We had tremors at 10.34pm and I could see the chart figures moving.
Need more data as part of the report and file saving with Inputs.
Not sensitive at all. Violently shake the phone, its sensitive for a while.. then wont detect anything at all
Without instrument. Easy to taken reading. Very very useful.
Can we take a full pic of the graph if was more than 15 sec. Like may be a 60 sec vibration. That would be nice
The app is great and for everyone who is scared from the camera usage it needs it in the premium version for the flashlight for the sos Strobe
Still can not manage to conclude whether it works realistically.On the whole it's great.Thanks dear Developer.
One of the best apps I have used if you need to measure any vibration get this app the slightest touch, and this app will sense it well done to all those people involved in the making of this app
It uses camera permissions in the background and has lots of ads.
Really great app. Using to check machine vibration and its quite close to proper equipment
Awesome app! Greatly helps me on dynamic balancing the motor fan.
Suspicious behavior! Several times system reported that this app is using camera in background.... 😵
Very useful app If you think you feel the earth shaking Turn on this amazing app and verify what you feel
Randomly uses camera long after dormant in background.
It is real. I can know when there is an earthquake or any thing.the best thing
I have this on my Samsung tab a and love it's sensitivity. I agree with others that I wish there was a way to drag what's been recorded, but data can be exported with premium (which isn't badly priced either).
