On the level

On The Level works just like a handyman's level, but has a couple of extra helpful features:

* There is a sound option which will audibly tell you when you are getting closer to level and when you are dead on!

* You can calibrate the level through either a simple 1-button calibration or through a 2-button calibration which works when you don't have a known-level surface!
