## What is Angle Finder?

Angle Finder+ transforms your iPhone into a precision digital protractor and inclinometer. Measure any angle or slope with the built-in accelerometer for carpentry, construction, and everyday tasks.

Place your iPhone on any surface to instantly read the angle of inclination. Use the on-screen protractor to measure angles between two surfaces, or hold the phone against a slope to get the exact pitch.

Key Features:
- Real-time angle measurement using accelerometer
- Digital protractor with 0.1° precision
- Inclination and slope measurement
- Hold-to-lock angle reading
- Reference angle setting for relative measurements
- Visual bubble level indicator
- Roof pitch and grade percentage display
- Calibration for accurate readings

Perfect for carpenters measuring miter angles, roofers checking pitch, DIY enthusiasts leveling shelves, or anyone who needs quick and accurate angle measurements on the go.
