Comments on Protractor for Android

★★★★☆ S DK · Sep 11, 2016
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.
★★★★☆ A Google User · Jan 11, 2015
Liked it on hudl 1 A very good app. Good job but a bit sensitive to the touch still I would recommend it to everybody out there who needs to measure angles
★★★★★ Simon Simpson · Apr 16, 2021
Very useful. Take a photo. Measure the angle. Pretty useful. No protector needed. Excellent.
★★★★☆ Judson Blue · Jul 28, 2016
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. 👍
★☆☆☆☆ A Google User · Sep 23, 2014
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.
