User Comments:

• "While I can see this has real potential applications, the only semi-serious use I've had is showing my 95 year old grandmother that her washing machine was out of balance. (Fixed it) The look on her face was PRICELESS. Thanks!" - by KeyboardError

We were featured in "The Independent Guide To The iPhone 3Gs" by Nik Rawlinson. Here is his review:

"This is a novelty app but one that also helps you learn something new. The concept is simple. You just leave your iPhone on a hard surface with the app fired up, then tap somewhere nearby and watch what happens.

It looks like something you would find in a hospital, but it's one of those things that is very captivating once you've looked at it once. We completely lost track of time when we played with this app, trying out different tap-based compositions - it was like we were at an MTV concert during this review.

You have the ability to pause the 'recording' of movement around the iPhone, in addition to looking at a colorful spectrum graph of what occurred in the three seconds prior to requesting that data.

We didn't quite understand what the chart was showing us, but it looked pretty nonetheless and it'll make you look very intelligent to anyone looking over your shoulder.

The app will monitor movement for 10 seconds and report back on the last three seconds of activity. You can then upload that data in a snazzy graph format to the web for all to see. Your old friends will probably think you've changed careers."
