About Protractor PRO

Protractor PRO is a great tool to help you solve everyday problems. Measure any
angle in no time. The app uses the camera and projects a protractor on top of the camera view.

It is a perfect tool for every professional whose job requires measuring angles.

It works just as well as a real protractor and could help you determine quickly the angle between two lines.

The app has two modes:
- Normal mode (the protractor is fixed and you move your phone)
- Zoom mode (move, zoom in and out the protractor)
Switch easily between Normal and Zoom modes with a single button.

It also includes three different protractors for any occasion and the option to turn off the camera in case it distracts you.

Measure angles with great ease.
