Protractor Angle Meter

Protractor Angle Meter is a simple photo-based tool for checking angles quickly. Take a new photo or choose one from your library, then place the pivot and two guide lines directly over the object you want to measure. The angle is shown in large, easy-to-read numbers, always as the inner angle from 0° to 180°. The app is made for moments when you need a clean visual reference instead of a complicated measuring workflow. Use pinch zoom and pan to line things up precisely, double tap to return the image to full view, and turn on 15° snap when you want fast, steady alignment. Gentle haptic feedback helps each adjustment feel clear. Every measurement is saved automatically, so there is no save button to remember. Your history keeps square thumbnails, the latest angle, and the update time, making it easy to return to past checks for DIY work, crafts, drawing, study, setup, and everyday angle comparisons.
