Apple Compass Gyroscope

The compass dial rotates smoothly in real-time based on the device's physical orientation, driven by the gyroscope. Tapping the dial locks a target bearing (marked with a white line and degree text). As the user rotates away from this locked heading, a vibrant red arc expands dynamically to visually represent the degree of deviation, accompanied by a rotating red needle. The degree readout at the bottom updates continuously with a rapid ticker-like text transition.
