Measure any angle on screen or through the camera in degrees.
Measure any angle without a physical protractor. Drag two arms across your screen, aim your camera at real objects, or rest your phone on a slope to read live tilt.
Protractor puts a full angle-measuring kit in your pocket for DIY jobs, trade work, homework and quick checks around the house.
FEATURES
- On-screen angle finder: drag two arms over a photo or live view to read the exact degree
- Camera angle overlay: point at a wall, roof, ramp or shelf and capture the real-world angle
- Live inclinometer: turn your phone into a tilt gauge for degrees, percent grade and roof pitch
- Instant units: switch between degrees, radians and slope grade in a tap
- Save each measurement with a thumbnail and revisit it anytime
- Fully offline, no account, clean native design
HOW IT WORKS
1. Pick a mode: on-screen, camera or inclinometer
2. Drag the arms or aim your phone to line up the angle
3. Read the exact value and save it for later
