how many clicks does it take to get to the part where you can actually measure angles? it's about a 30-second wait and three ads. Even then, it didn't do what I needed.

Basically unusable, at least without instructions that don't seem to be built into the app. Aside from an incredible number of ads for a very basic app function, I also just can't figure out how to see the angles against something useful, like the camera. An image of a protractor, with lines to mark whatever angle I need, is not valuable in complete isolation from the object I'm trying to measure.
