Hinge Angle Meter turns the iPhone Duo fold into a practical measurement tool

Available now on the App Store, the Appsolute LLC utility uses the physical hinge as live angle input and adds level, target-angle, AR distance, history, and Apple Watch tools.

Appsolute LLC has released Hinge Angle Meter, a measurement utility designed around the physical hinge of iPhone Duo. As the device opens or closes, the app follows the changing fold and presents the angle live, turning the phone into a compact digital bevel gauge.

The app also includes exact 90-degree guidance, copy and complementary angles, a pitch-and-roll level with zero calibration, custom targets, camera-based AR distance measurement, saved readings, and an independent Apple Watch angle gauge. On conventional supported iPhone and iPad models, the angle and level tools use motion sensors.

Hinge Angle Meter is available on the App Store. The verified U.S. price is $0.99, with local pricing shown by Apple. The app requires no account or internet connection, contains no advertising or analytics, and keeps measurements on the device.
