Hello, this is a free tool that I made. The idea was simple, everyone already has a electronic device, so why not add the ability to use it as a protractor.

To use it, you can simply move the compass to the angle you need, and place a paper over the screen to trace the angle.

Likewise, you can also use the tool to measure angles in images. You can upload an image, and move the image around to measure angles.

I am working on improvements so any feedback is greatly appreciated.
