Camera Protractor: Angle Meter

Turn your iPhone or iPad into a camera protractor, photo angle meter, and surface inclinometer.

Measure angles from photos, live camera views, or real-world surfaces in seconds. Check slope, roof pitch, and miter cuts, save your measurements, and share the results.

Three ways to measure. One simple angle toolkit.

THREE WAYS TO MEASURE

PHOTO
Choose a photo from your library or take a new one, then place three points to measure an angle.

CAMERA
Use the live camera protractor, freeze the view, and fine-adjust the measurement points for greater precision.

SURFACE
Use your iPhone or iPad as an inclinometer to measure tilt from horizontal, slope percentage, and roof pitch.
