Turn your iPhone or iPad into a digital protractor. Check angles in the camera view, measure over a photo, or use the on-screen protractor for quick geometry and DIY tasks. THREE WAYS TO MEASURE • Camera: position three draggable points over the angle you want to check. • Photo: choose an image from your library and adjust the measurement points. • Measure: move the protractor pointer and read the angle and its supplementary angle in degrees. KEEP THE RESULT Use fullscreen for a larger view. Lock a measurement or enable angle snapping when needed. Save a PNG measurement image to your photo library, or share it through the system share sheet. MADE FOR EVERYDAY ANGLE CHECKS Useful for geometry homework, classroom examples, diagrams, crafts, woodworking and visual checks during DIY planning. CHOOSE YOUR LANGUAGE The interface supports English, French, German, Spanish, Portuguese, Arabic, Japanese, Korean, Russian, Simplified Chinese and Traditional Chinese. Switch languages from the top-right language button; your choice is saved. LOCAL PHOTO PROCESSING No account is required. Photos and measurement images are processed on your device.
