This is just the thing for students of Art, Technical Drawling, Design, and other like professional trades. Even if you are just a hobbyist looking to up your game. I honestly have used and benefited from this app. I will be getting the full version next pay day! I hope this review helps anyone trying to decide on getting this app.

Great demos that are easy to follow. Nice having the ability to change speed & practice with a self check.

This thing doesn't work anymore! I was just getting the hang of it to start using it with my students, but it is not compatible with iOS 7. Hope it gets fixed soon!

This is a nice way to practice constructions without lugging around a compass. I would suggest making the "check" button recognize more variation, as I did some of the constructions correctly but it didn't like that I made the arc too long, etc.
