Vibration
Coolest app yet!!

Needs longer sample size
I want to use this to measure vibration of car suspension. Current samples way too short. Please extend.

Yes a very good app to balance quadcopter motors and props. Even motors straight out of the box won't be balanced as good as you can get if you use this app.
A BSR/NVH engineer's must-have
Anyone needing to characterize noise, here is the perfect app to get. There are many ways to use this cool "tool". I used it as a stopwatch by setting it up to trigger from z-axis motion, since my challenge was to time movement occuring in less than a second. This app lets one record the noise AND measure the vibration, or other movements, to give variable data to an otherwise subjective claim about what is heard. It can easily capture and email all the information: audible, graphical and g-force data.Other uses include getting data for performance of vehicle cornering, machine operation, and playng music. I let many of our automotive engineers know about this.

Excellent
Have used this app to assist with vibration dampening on a RC Quadcopter carrying video equipment. Prior to testing the individual arms of the model I was getting a fair amount of vibration with the video footage. Using the Iphone and this app I have been able to balance the motors very precisely resulting in exceptionally smooth video.
The money I have spent on camera gimbals etc has been a fortune, this App would have saved a fortune as it as highlighted some major imbalances in the motors which no gimble could have dampened. Wish I had discovered this earlier, now have two multicopter platforms producing very smooth raw footage.
Actually works am very pleased with results

Excellent app
Does a very good job of capturing short term vibrations so they can be compared for diagnostic purposes.
I intend on using it for server preventative maintenance to compare vibration levels over time to see if we can pick up issues with drives and fans before the fail completely.
I guess it could also be used on engines to check for changes to rotating parts and bearings that could indicate problems.
It'll take a while to see if it's suitable for those applications, but it'll be fun checking it out.
One nice feature is sending the sample out by email, it does a date and time stamp in the subject line and you can add your own notes. It sends the data in a csv file that can be used for comparison with previous samples. A clean way to get data quickly off the phone and where you can use it.

I love you guys
I have never found a app I will depend on as such as this. Amazing work guys completely worth the $4.99
Time base warning
Excellent app! However the sample rate must be less than 20 or time base warning message appears (iPhone4). Tried recommended calibration but no improvement.
This app saved the day
For months we've been having issues with hard drives failing within servers due to vibration.
With this app, and placing the iPhone on top of the hard disk, we were able to test different fan configurations until we brought vibration down to 1/4 of what it was before.
We didn't have to buy a $1k vibration meter. This was enough. I would gladly pay more than the $5 this app costs!

Wow.
For the price this is amazing. I might not have been too surprised to find out that buying an instrument to do this job cost thousands of times that. Very nice and tidy.
