About this app
Protractor turns your foldable phone into a real protractor. It reads the hinge angle sensor and shows the angle between the two halves of your device, live, as you fold and unfold.
FEATURES
• Live angle: current hinge angle updates as you fold
• Honest precision: shown with the actual margin of error your sensor has
• One-time calibration: fold and unfold slowly once, and the app learns your sensor's resolution
REQUIREMENTS
Works only on foldables with a hinge angle sensor.
