Hinge Angle Meter
Level, length and AR ruler
Hinge Angle Meter bundles several measurement tools for iPhone, iPad and Apple Watch. On supported folding devices the physical hinge acts as a bevel gauge: one side shows a large live angle, the other keeps the controls in reach. On other supported iPhone and iPad models, motion sensors drive the angle and level tools.
Features include live angle measurement, exact 90° guidance, copying and reproducing an angle, complementary angle calculation, pitch and roll level with zero calibration, custom target angles, AR distance measurement with the camera, and a local measurement history. The Watch app runs independently and turns the Digital Crown into a target-angle control. The developer states no account, ads, analytics or internet connection is required; measurements stay on the device and AR camera frames are not stored or transmitted.
Why no subscription? The App Store lists the app at $0.99; the developer’s text mentions no subscription requirement.
