Protractor Measuring Angle

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.
