Features & Capabilities

Turn your screen into a precision angle meter. Drag two lines to measure any degree — or point the camera at any surface and measure angles live.

Screen Protractor is the precise, easy-to-use angle measurement tool that turns your iPhone into a digital protractor. Move two measurement lines anywhere on screen and instantly read the exact angle between them — down to the degree.

MEASURE ANGLES ON ANY SURFACE Enable the built-in camera to use your live feed as a background. Hold your phone up to any object, surface, or corner and measure angles in real time without printing anything out or carrying a physical protractor.

User Reviews

I tried & deleted 2 other protractor apps before this one. This has a protractor where all 360° are visible. Zooming in can be done by holding the dot in the center and pinching (not sure if that info was in the popup I immediately closed). There’s even a way to reset to the original view. The camera can be turned on/off, and even paused so you don’t have to hold your phone still while measuring angles which is nice. The app rotates with your phone, but *the camera has a bug* that rotates the wrong way. The app does not automatically read angles according to your phone’s orientation, nor does it convert to radians which I don’t care for, but it does what I want without pushing ads :)
