Vibration

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-forc

Coolest app yet!! Yes, I'm an engineer.

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.

The program seems to work ok but the calibration crashes and ends the program.

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.
