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.
Simple and effective
I’ve used this for several years to collect vibration signals from vehicles and trickier s for research purposes. It’s easy to use and I recommend to my students.
Brilliant app
Does exactly what it claims to, measures vibration up to 50Hz.
Lots of control regarding sampling rate, time and delay.
Files can be saved and exported as CSV.
Spectrum analysis could use some more labels but nevertheless very good app.

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.

Lovely!
Great app. I use it to analyse resonance and vibration in my 3D printer as I add and replace components. The ability to email the data to myself in spreadsheet form is much appreciated.
slightly disappointed by the update
Whilst it is 'technically accurate' I found the claim that "It is now possible to select an external microphone as a data source" rather misleading.
In fact, it appears that the in-App purchase [at a cost of £14.99] serves to only "Enable full Digiducer functionality".
The Digiducer itself is an excellent, but not inexpensive device, and I would have been MUCH happier if the option was available to use ANY external USB microphone for qualitative work.
That said; the App remains excellent !!

Note: I have already twice attempted to submit this review, but neither has appeared ... Perhaps that was because I included links to the Digiducer website. [?]

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.
Great app.
This app turns determining natural frequencies from a 20 minute exercise to a 5 second one. Very well put together! You've made my calcs a lot easier!
