Read full descriptionHide full description
The Surface Coach app supports our training concept, which is deeply rooted in our culture and different from traditional gyms. Members can enjoy individual coaching and on-measure programs via their personal Surface Coach app, which works in synch with the receivers installed at the gym. The Surface Coach app provides real-time information on your workout and training session so that you can conveniently adjust your effort to suit your training goals, such as tracking your actual heart rate, HR training zone split, duration, or calories burned. The Surface Coach automatically synchronizes each new training session with your account to provide a complete overview of your progress with daily and weekly reports as well as an accurate and detailed analysis of all your workouts. The app is available for Apple Watch (watchOS 8.7 or greater). The app receives heart rate data through Apple Health when using the Apple Watch.
