Notch is made up of a series of wireless sensors that can attach to clothes via small straps. Packed with accelerometers, gyroscopes and compasses, it’s able to record the user’s motion and then relay that information in real time to the companion smartphone app to see a 3D view of the movement.
Aimed at athletes including boxers and runners as well as therapists, the company uses its own algorithms to capture and analyse range of motion data. That should give you or a coach an insight into form and posture, making it easier to identify problematic areas with technique. It’s also waterproof, which means swimmers can take advantage of the tracking tech as well.
