Protractor Smart for iPhone

Overview and purpose

Protractor Smart is a complimentary utility for iPhone that turns your device into a precise angle measuring tool. Built by ExaMobile S.A., the app makes it easy to determine the inclination of walls, natural formations, structures, and other objects you encounter.

Measurement options

Protractor Smart provides two distinct methods for taking angle readings:

• Plumb (pendulum) measurement — uses an internal pendulum to assess slope; make sure to run the calibration routine before relying on results for accuracy.
• Touch-based camera measurement — set angle points directly on the live camera feed by tapping the screen for quick, visual readings.

Camera integration and snapshots

You can switch to the camera view at any time to overlay measurements on real-world scenes and save what you see. The app lets you capture screenshots of the screen with the measurement overlay, which is useful for documentation or sharing results with others.
