NVH

I have been working on acoustical diagnostic processes for a little while. My direction is on seizing and harnessing different signal capturing and transmission of vibrations and more direct analysis as compared to a program tic analysis like this app features. In my approach I am acquiring signals from the engine, to include engine rpm from cylinder 1 spark plug during events then visually looking for correlating events from concurrent signals being recorded. It I a more raw and base way of doing what this iPhone app does for me so eloquently. I can see how this app can be extremely useful in my diagnostic approaches. Very clever app.

Love everything about it!!

Found so many issues on trucks and cars while using this app❤️

Purchased this app after taking a NVH class. Love using this app for weird concerns or training newbies. Right now you can only print the PDF readout which is useless to me and the customer. I would rather print the graphed data. Right now I’m zooming in and using screen shots

The app is really helpful , but I request you to add the Toyota LC300 model also to the list

This tool works great it has solved many vibration issues for me I am trying to figure out how to share it with my other phone I can’t seem to find the family sharing on this old version

It just takes a little bit of time using this app to get good at it.

Had two vehicles with drive shaft problems. One was a trailblazer that turned out to be a badly worn out rear u-joint which became much worse with acceleration. Despite confirming the proper setting on the app and a lengthy test drive, NO drive shaft vibration were noted on the app. The next was a Chevy Colorado with an annoying vibration that was worse between 50 and 70 MPH. Also showed NO indication of drive shaft vibration. After exhausting tires, rims, rotors, and the like, had the drive shaft balanced, the vibration was gone.

The app doesn’t show what corner or where the vibration is coming from, just that there is one and the entire list of many places you can look at - I already know that - pointless . The app has no trial or option for a refund. The company behind the app just took $400 for no value to me - don’t make the same mistake as me. I tried to contact them via the support link and of course, I didn’t hear back.

Useless app
