Great App, does exactly what it says without clutter. 3 modes each useful for variety of tasks, drawing and measurement based. Interesting use of your phones camera to impose protractor image over. Haven't really tested this mode much, but was pleased to discover this ability and can see numerous situations where this could be useful practically.
