Customer Reviews

Surprising the iPhone has this high resolution!

Nice simple application, showing that the iPhone can resolve better than 0.5 degrees. Unfortunately the calibration limits are too tight for my "2G" iPhone - I can only calibrate it to zero if I tilt the phone a little to one side.


It has been a looooong time since the last update.
Don't you think it's time to step ahead?

Great app

I brought this app for free back then and now it's not
