Protractor

I dont know it could be because of my phone. But the readings are inaccurate. The angle of same corner observed using the app gives different reading depending on the orientation of the camera (i.e holding phone in landscape or portrait view)

Because of the solid angle. I can't see where I am putting the protractor. It's not translucent enough. Also there should be an option to zoom in on the image.

Gets the job done. Perfect app for measuring any kinds of angles, anywhere, whatever the orientation may be. Keep up the good work!
