## What is Protractor+?

Protractor+ Angle measures angles precisely using your iPhone's gyroscope and camera. Whether you need to measure a surface angle, check a slope, or verify construction geometry, this app delivers accurate results.

Use the gyroscope mode to measure angles by placing your phone on any surface. The camera mode lets you measure angles visually by aligning reference lines on your screen with the edges you want to measure.

Perfect for carpentry, construction, DIY projects, and educational purposes. Measure roof pitch, pipe angles, furniture assembly angles, and more with professional-level accuracy.

Hold and lock readings for easy reference. Switch between degrees, radians, and percentage slope formats. Clean, precise interface designed for quick measurements in the field.
