SmartProtractor turns your iPhone into a professional angle-measurement toolkit. Whether you're a carpenter setting bevel cuts, an architect verifying site angles, a student solving geometry problems, or a DIY enthusiast leveling shelves and frames — get accurate readings in seconds, no extra hardware required. 4 MEASUREMENT MODES TOUCH PROTRACTOR Drag two colored handles to measure any angle on screen. Switch between 180° and full 360° modes. Enable snap-to-angle for instant exact values at 5°, 10°, 15°, 30°, and 45° increments. Lock any measurement to prevent accidental movement, then export a clean annotated diagram. CAMERA OVERLAY Overlay a live protractor on your camera feed. Aim at any object — a roof truss, door frame, staircase, or mountain ridge — and read the angle in real time. Pause to freeze the frame, fine-tune the arms, and save or share the annotated photo. PHOTO MEASUREMENT Import any photo from your library. The protractor overlays the image automatically, and you can drag it anywhere across the photo to place it exactly where you need. Adjust arms independently, pan and zoom the photo, then export the composite with the angle annotation included. POLYGON TRACING Tap anywhere to place polygon vertices and trace any irregular shape. All interior angles calculate in real time. Tap the first vertex to auto-close the shape and instantly verify the angle sum — triangle = 180°, quadrilateral = 360°, and so on. Load a photo or use the live camera as background to trace real-world objects directly on screen. LEVEL & INCLINOMETER Measure device pitch and roll with the precision of a digital spirit level. Calibrate to any surface, lock the reading, and switch between pitch and roll axes on a precision dial display.
