How do you measure angles?
Overlap a plastic protractor with the angle? Use a camera app superimposing a picture of a protractor? It will become obsolete if you use Handy Protoractor.

Instead of meauring angles by a plastic protractor, Handy Protractor enables you to measure angles only by turning your iPhone.
Its very simple and easy!
Besides, Handy Protractor can measure angles of three-dimensional objects flexibly. You can measure angles anytime, anywhere.

Measurements are done by using a built-in gyroscope.
The angles can be displayed in radian and degree.
