ONE-LINER
Hinge Angle Meter turns the physical iPhone Duo hinge into a live digital angle gauge, with level, target-angle, AR distance, history, and Apple Watch tools.

SHORT DESCRIPTION
Hinge Angle Meter turns the physical iPhone Duo hinge into a live digital angle gauge. Open or close the device and the reading follows the fold. The app also includes level and zero calibration, target and complementary angles, AR distance, local history, and an independent Apple Watch angle tool.

LONG DESCRIPTION
Hinge Angle Meter is a focused measurement toolkit built around a new kind of input: the physical fold of iPhone Duo. On supported folding hardware, opening or closing the device changes the live angle reading, so the phone can act as a compact digital bevel gauge. The interface separates the large instrument from its controls across the available surfaces and includes visual, sound, and haptic guidance. Beyond the hinge, the app offers exact 90-degree guidance, copy-angle and complementary-angle tools, pitch and roll level with zero calibration, custom target angles, camera-based AR distance measurement, and a local measurement history. A standalone Apple Watch app adds a Digital Crown target, Zero, Hold, and saved readings. Conventional supported iPhone and iPad models use motion sensors for angle and level tools. No account, advertising, analytics, or internet connection is required, and measurements stay on the device.
