Kinapod Disc is an app that turns a single AirPod into a flying disc tracker by mounting it at the disc's center. It measures spin rate, revolutions, release speed, and airborne time using the AirPod's gyroscope and the iPhone's microphone, with optional spoken feedback and support for both solo practice and two-player rally modes.
An interactive visualization tool that draws a wheel and displays the road surface it traces as it rolls. Users can adjust wheel parameters, axle configuration, and road geometry to see how the wheel's motion path changes in real-time.
