Customer Reviews


Excellent App. Easy & quick to use for the pro and a good learning tool for the beginner with references & explanations of all the DOF terms.

Awful Interface

The app provides all the information you need (no inches, stops at 1 foot). But the process of getting there is painful. Keyboard entry for just about everything.

Calculations are incorrect?

The results I get from this app are vastly different than the 4-5 other apps & online calculators I tried, all of which gave similar results.
