Good job Thanks a lot. I've been searching for an app that does this, exactly the way it does it. 🙌. Time for me to uninstall all the other protractor applications. 👍

Nice app easy to use. The blue pads may be made more transparent. Unable to see the background clearly for precise measurement. Also zoom in and out facility will be very helpful. Thank you.

yeah this one is the best it allows you to take a picture and then mark the lines you want the angle for, tried a few, this one was the best

Great idea. Lousy implementation. The concept is excellent. Dragging the vertex and two endpoints over an image to simply and directly measure an angle is the way to do it. Many other protractor apps don't get that. UNFORTUNATELY this app seems to do a really poor job of implementing that idea though. In Camera mode the camera doesn't work... I get 3 squashed live images on the far side of the screen and 85% of the screen is blue. So then I tried using Image mode, but wouldn't go full screen, and drag handles are very clumsy.
