Up to now, motion analysis has always required a fixed lab setting. This product breaks this limitation, enabling athletes to analyze their motion anywhere in the real world. This is also the world's first modular wearable device. The user can select battery, display size, and mounting method, making the device adaptable to numerous sports. As of launch, cycling motion analysis apps are included with the hardware, and all software can be updated via FOTA. Web-based software and smartphone companion apps are also provided, empowering real-time motion analysis and professional coaching support, both in-person and via remote settings.
