AngleSense

AngleSense turns the posture of your device into a clear, live angle reading. On iPhone Duo, AngleSense reads the real hinge angle, turning the device into a convenient digital protractor as you open, fold, and reposition it. On other iPhone and iPad devices, AngleSense uses motion sensors to measure device inclination: 0° when lying face up, 90° when upright, and 180° when lying face down. Features: • Live angle measurement • Target-angle challenges • Automatic stability detection and result reveal • Challenge history and average error • Separate hinge and inclination records • Haptic feedback and display precision settings AngleSense requires no account, contains no ads, and works without a network connection. Angle readings and challenge history stay on your device.
