In this interview, XR developer Yin-Chien Yeap discusses how HoverFit combines full-body fitness, multiplayer racing, and browser-based VR to deliver a unique workout experience. He breaks down the technical choices behind building for WebXR, how Olympic athletes shaped the design, and the challenges and future of immersive content on the web.

Before getting into the interview, I wanted to quickly introduce you to today’s sponsor Gracia AI. Gracia AI is the only app that allows you to experience Gaussian Splatting volumetric videos on a standalone headset, either in VR or MR.

It is a truly impressive experience and I recommend you to try it out right now on your Quest or PC-powered headset.
