Juste iPad rotation is missing

This is a very very good app for lift/drag demonstration of any objects because you draw them !!

Anyway, as I state in the title, if developpers add the iPad rotation to control the flow angle, it Will be a PERFECT app, more useful, and better to illustrate lift/drag at any angle of attack, just by turning (banking) the iPad...

With this update, I Will add the 5th star !!!

Thank you ;-)
