myFrequency FREE - Vibration Analysis
You can use this userfriendly and mighty app as an accelerometer to detect vibrations / oscillation, natural frequencies / eigenfrequencies and damping values of objects, machines and structures. Furthermore you can detect cable forces of cablelike elements like hanger of bridges. The tension force / prestressed force of a rope or wire will be calculated due to the first natural frequency of the cable.
Main features:
- Real time measurement of accelerations in all three axes (X,Y und Z)
- Real time frequency spectrum while measuring
- Storage/Reloading of all your measurement files on your device as .txt files
(transmission by e-mail)
- FFT-analysis of signal - generation of frequency spectra
- Userfriendly interaction with frequency spectrum
- Determination of damping values out of decay processes
- Detection of natural frequencies of structures
- Detection of cable force due to vibration measurement
- Detection of maximum accelerations and RMS-values
How to use the app:
Simply place your smartphone with the myFrequency app as an adequate alternative to a professional vibration meter ( vibrometer ) on any vibrating object and determine the relevant natural frequencies/ eigenfrequencies in just a few seconds. You can use this app also as seismometer to detect earthquakes.
The acceleration sensor records the vibration in all three axes and stores the signals in a text file on the device for direct analysis on the smartphone or for subsequent processing on the computer. The data can either be transferred via USB cable or directly in the app with an e-mail to the computer.
In addition to the frequency with the maximum acceleration amplitude, all other excited frequencies can be individually selected by swiping your finger over a detailed view of the spectrum.
This is a test version, to enable all features of the app please download the full version.
We hope to offer you an application that you can use for all kind of vibration measurements, in structural health monitoring also.
If you have any questions, comments or suggestions, please contact us so that we can continue to develop the app.

does what it says and seems like a solid app but not what I'm looking for. wish it could display velocity (displacement would be great too) with option for RMS, pk, pk-pk. doesn't look like the fft units can be changed (to cpm) either. hopefully in the future. would gladly pay for those features, can't seem to find an app that does this.
Excellent. It is good software that i have seen on mobile. It would be great, If we add hardware probe connection feature and use it in tablet for including more analysing features. I will recommed to apply it in industry.
Great app. Very intuitive, easy to use and read. The instantaneous analysis is great for real time evaluation and comparison of vibrations. It provided immediate answers without expensive and complicated equipment.
Love it. Extremely sensitive and useful. I can make sure it works properly on my phone b4 I purchase the pro version
It does almost nothing of what it advertised, everything is available "only in Pro mode".
Absolutely perfekt app. I used it to estimate the natural frequencies of a footbridge in Uganda.
Best vibration app I've found. Need the PRO version for multi-axis analysis but pretty impressive even in single axis mode
Still figuring it out-great so far. Can I calibrate the app if I can't get away from the sound I'm trying to measure?
Keeps asking to go pro and in doing so you rate this app. Sadly it still will not go pro.
Does not work , hit new measurements and it forces app to close
looks promising ... I can hardly wait to test it on my car vibrations!
amazing, super good and easy to use!!!!!
The free version is praxtically useless
very useful for me as a structural engineer
Very nice but some functions are not working.
Its ok but I like free apps lol with good quality settings
Works like a champ I have learned a lot thankyou
No frequency measures without purchasing pro
Not useful at all
Waste of time app
I will test
As a practicing structural engineer that evaluates the vibration characteristics of elements(beams,floors,walkways,etc.) this app become a powerful tool next to a lab equipment. Love the FFT funtion.
Free version is a total sham, basically, its only function is to prompt you to go Pro. Pro version is somewhat usable, but far from perfect: no horizontal zoom, neither in time, nor in frequency domain, no peak finding, no numeric display of either peak frequency or amplitude. Zeroing on a peak manually is rather difficult without zoom. Saved files are not comma-separated, and bizarrely, the timestamps appear to be expressed in nanoseconds, so you can’t even see them changing unless a double-precision variables are used to store them.
