More on the VAY Fitness Coach

2018 we wanted to create a T-Shirt that understood human movement and was able to give feedback in real-time on fitness exercises. After building the prototype, we realized that the sensor-stuffed T-Shirt was too expensive and obtruded the user experience.

At this time computer vision (CV) algorithms started becoming fast enough for consumer products. So we set ourselves on the journey to create a fitness coach app that is powered by CV and more specifically human pose estimation.

One and a half years later, we were ready to enter and disturb the fitness app market. During development, we still focused mostly on the underlying core technology: our human pose estimation algorithms.

The app is currently available on the App Store and the Play Store. Coaching from world-famous coaches belongs to the premium part of the app. In the free section users can compete in challenges against the world or their friends. Get your free trial now.
