What does Hinge Angle Meter do?
Hinge Angle Meter turns the iPhone Duo hinge into a live digital protractor. Open or close the phone and the angle reading changes in real time. A screen-swap control moves the controls and readout between the two halves when the system animation covers one display. The app also includes a two-axis level, AR distance measurement, target-angle alerts, local history and an Apple Watch companion. Measurement tools work offline. It costs $0.99 once, with no subscription.
