Protractor Measuring Angle turns your iPhone into a precise digital toolbox — measure any angle, slope, or distance in seconds. 8 TOOLS IN ONE APP ▸ Inclinometer Real-time tilt measurement using your device sensors. Edge mode reads walls and frames; Flat mode works face-up on surfaces. Tap Calibrate to zero any offset. Freeze the reading with one tap. ▸ Screen Protractor Drag two arms to any angle and read the value instantly. Perfect for blueprints, technical drawings, and any image that needs an exact angle. ▸ Camera Level Live camera with a horizon overlay line. Freeze the frame to capture and save the reading. ▸ Photo Angle Measure angles directly on photos from your library using the same drag-and-lock protractor. ▸ Height Calculator Point at the top of a tree, building, or mast. Enter the distance to its base and your eye height — the app computes the exact height using trigonometry. ▸ AR Measure Drop points in augmented reality to measure real-world distances and the angle between any three points in 3D space. ▸ On-Screen Ruler A calibrated ruler in centimeters or inches. Run calibration once and it stays precise on your device. ▸ Compass Digital compass with cardinal and intercardinal directions. FLEXIBLE UNITS Switch between degrees, radians, percent slope, and roof pitch (X:12) for angles. Length reads in cm, in, m, or ft. MEASUREMENT HISTORY Every saved reading is logged with a thumbnail, timestamp, and optional note. Review, edit, or share any past measurement. Works offline. No account needed.

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. Sharing only happens when you choose to share. The app contains ads. An optional one-time in-app purchase removes ads; no subscription is required. Measurement accuracy depends on point placement and image perspective. This app is for visual reference, not a replacement for calibrated tools in safety-critical or professional measurements.
