SlopeEZ: Image Angle Measurer play online

This app allows users to measure the angles in a photo, with three modes!

Freeform angle selection mode projects three dots onto the photo, which form an angle. The angle can then be maneuvered on the photo to measure any angle in it. You can scale and measure distances in this mode; AI mode automatically detects and places lines on all edges for you.

Level mode uses the phone's gravitational sensors to display the orientation of the phone in 3d space, allowing your phone to be used as a level!

Protractor mode superimposes a resizable, rotatable, and movable protractor onto an image from the user's phone's storage which the user can then use to measure any and all angles in the image. There are multiple styles of protractors to choose from, and more than one can be added to the image. The app can be locked to prevent the protractor(s) from moving and the screen orientation from changing.
