Dual Level App Reviews

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. Dont you think its time to step ahead?

Needs retina display

Also very jumpy performance. The bubble jumps from one end of the bar to the other!

Its accurate for me on my iPhone 5
