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!

Bad
Apps should never ask for AppleID password
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.

Calibration issues
The program seems to work ok but the calibration crashes and ends the program.
This App turns your iPhone into a $2,500+ piece of scientific equipment
This is a wonderful scientific app that specifically shows how powerful an instrument that most people never realize they carry in their pockets.
I've used this app to conduct a limited vibration analysis of an apartment that complained about vibrations caused by newly installed chiller pumps in the building.
I'm amazed at how sensitive the internal accelerometer is on the iPhone 5. I was able to detect vibrations creating a surface delta of 0.02 mm/s @ 5KHz.
Kudos to the developer.

Very useful ap!
Best $5 I ever spent. Helped debug testing we're doing using very expensive equipment. Would be nice to have higher sample rate, but I guess this is limited by the iPhone.

This is a well written very functional app. A lot of thought has gone into the interface.
