Vibration - Reviews, Revenue and Downloads - Apple App Store

Description

Vibration is a true vibration spectrum analyzer using the built in accelerometers and gyroscope inside the iPod Touch and the iPhone and starting with version 3.x it can sample the built in microphone and the Digiducer professional quality external USB accelerometer. It acquires and displays time series data, optionally removes DC bias, applies a Hamming window and performs an FFT on each channel to produce frequency spectra. The 3-channel accelerometer has a sensitivity of approximately 0.02g and a range of ±2g making the iPhone and iPod Touch sensitive enough to analyze the vibration of most moving machinery.

In many applications Vibration can be an excellent portable alternative to a commercial spectrum analyzer. In predictive maintenance applications Vibration can help identify bearing defects, shaft misalignment, imbalance, and structural resonant frequencies. Vibration is also useful for monitoring the acceleration of part and material handling equipment.

The software is flexible and easy to use. It was written to emulate the familiar oscilloscope based spectrum analyzer. Sample rate and sample delay are easily adjustable and the user can select the length of the data acquisition and the vertical scale used for the display. Once the settings are configured simply press the sample button on the device or on your Apple Watch. When a test is complete the resulting data can be emailed to your desktop computer for documentation purposes.

Features:

• Sample the built in accelerometer or gyroscope, the internal Microphone or the professional Digiducer USB products including the 333D01, 333D04, 633A01 and 435B39. Additional Digiducer accelerometer features can be enabled via in-app purchase.
• Adjustable sample rate from 10Hz to 100Hz for the internal sensors and 1 kHz to 48 kHz for the internal microphone and the Digiducer accelerometer (with in-app purchase)
• Trigger sampling and review settings using the Apple Watch companion app.
• Auto repeat and auto save allow data to be taken over extremely long periods of time.
• Selectable data length from 256 to 4096 samples
• Variable start delay from 0 to 20 seconds
• Adjustable vertical scale for time series data
• DC Remove option to get rid of the gravity vector
• Switchable Hamming window for frequency analysis
• Frequency data plotted as Linear-Linear, Log-Log, Log-Linear and Linear-Log
• Computes rms and peak levels for each channel and for all three channels combined
• Document your results by taking screen snapshots and syncing them to your computer or sending a CSV formatted email with the time and frequency data to your computer or saving data locally and downloading the data with iTunes
• Turn on and off individual frequency plots
• Calibrate the internal accelerometers and examine and edit the calibration data
• Optional sounds to mark the start and stop of data acquisition
• Data inspectors and zoom
• Triggering off one or more accelerometer channels or microphone input.
• Frequency data averaging and peak hold.

Further development and additional features are planned. Please use the email links in the program to request new features and report any problems.

Simple and nonfunctional

Didn’t work for me, might work for you. Randomly cut recordings short after a few seconds then locked up and tried to text the data file, at which the cancel button greyed out. Documentation looks like freeware from 1998.

Stopped working

I had this app for several years and it suddenly stopped working -- no longer records, saves or allows contact with developer. Disappointing.

Solid App

Bought this app over 5 years ago because the vibration sensor we were using in the lab wasn’t quite working for our need. We wanted to know the vibration noise source for a piece of equipment we were designing. With this app, we were able to determine the peak frequencies, and therefore the source of our noise. Impressed the whole team with the fact that it was an iPhone that solved the mystery. Ever since then this app has been a fun toy at home.

Mostly good, but possibly flawed

I was impressed to find such a technically advanced app. However when I use the microphone input on an iPhone, the sound frequencies appear to be represented in the spectrum view at twice their actual frequency. I haven't put it on the bench yet, but when I calibrate a whistle or sing tone with another app, the Cleartune app, the tones are represented in this Vibration app at twice the frequency registered in the Cleartune app. I have used the Cleartune app to practice various pieces of music and it seems spot on.

State of art, 5 stars application of the year!

It is a state of the art. The best program I have ever used in my life including all PC software.

Application Receipt Not Valid

When I try to use this, it says "Application Receipt Not Valid" and refuses to work. I think this constitutes fraud- it is a complete and utter RIP OFF RIP OFF RIP OFF RIP OFF RIP OFF RIP OFF RIP OFF RIP OFF RIP OFF RIP OFF !!!!!!!!!

Wont run with ios p ipad2

Was working before upgrading to ios 9 Now the app complains about some "...reciept[sic] ..." Problem and forces the app to close. How to get it working again, or is this a rip off!

Very Useful

I've had this app for sometime now and find it to be useful for measuring frequencies of all sorts of things. In the past it was vibrations, and now with the microphone added as a source, sound. Use it on both the iPad and iPhone.

Unable to load saved data

I have taken many measurements and saved them properly. When I go to load my data, there is nothing there. I reported this problem yesterday and have had no reply from them. Feel like I was ripped off of $5 that I paid. This has also wasted a lot of my time at work, which has cost me $400 in my time.

Nicely done

Very solid work around this implementation that provides useful data capture from the iPhone accelerometers in all three axes, as well as the gyroscopic sensors (though to a slightly lesser extent). Data is portable, GUI is flexible, acquisition parameters adjustable. Kudos to dev for continued refinement. Very fairly priced.
