From a VentureBeat.com online review:
Kaia’s iOS and Android apps were developed with the help of physiotherapists, pain management physicians, orthopedic surgeons, and clinical psychologists, the company claims, and are registered as Class 1 medical devices with the Food and Drug Administration. They serve up video clips covering basic back and COPD pain information and step-by-step physiotherapy exercises, in addition to psychological strategies, such as mindfulness and muscle relaxation.
During each of the over 120 15-minute exercises, in-app computer vision models track connective points on the body through a device’s front-facing camera while an on-screen wireframe model illustrates the steps. Audio feedback informs users whether they’re performing exercises correctly and how they might improve, and a built-in chat tool allows them to consult with a physiotherapist or sports scientist on questions related to specific moves.
