Angle Finder: Protractor Tool

Turn iPhone into a precision protractor. Real pitch and roll, bubble level, slope %, roof pitch (X/12), hold-to-lock — built for carpenters and DIY.

Angle Finder turns your iPhone into a precision digital protractor and inclinometer. Using your device's accelerometer, it computes real pitch and roll in degrees — perfect for carpentry, roofing, hanging shelves, and any task where angles matter.

Place your phone flat for surface mode (measure tilt of a tabletop or floor), or hold it on edge for vertical mode (measure the angle of a wall or beam). The bubble level shows when you've reached level, the inclinometer dial gives sub-degree precision, and the slope and roof-pitch readouts translate angles into the units pros actually use.

Key Features:

• Real-time pitch and roll from the accelerometer
• Bubble level with on-target indicator
• Inclinometer dial with live needle
• Slope percent and roof pitch (X/12) display
• Hold-to-lock current angle
• Tare reference for relative angle measurements
• Surface and Edge measurement modes
• Clean, dark, high-contrast interface

Perfect for carpenters checking miter angles, roofers verifying pitch, DIY enthusiasts leveling shelves and pictures, or anyone who needs accurate, instant angle measurements without a physical tool. Know any angle to a tenth of a degree.
