Protractor: Angle Finder

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 jobs 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

FULL ACCESS Full access unlocks with a subscription, offered weekly or yearly, or as a one-time lifetime purchase. Your plan is confirmed at checkout.
