This project is a native mobile app that creates personalized HIIT (high intensity interval training) workouts for users based on heart rate data from connected devices and scientific fitness assessments. Once the user's cardio zones have been set, the app guides the user through their personal HIIT workout. The optimal cardio zone is shown on the circle, with current heart rate indicated by the ball. Visual and audio coaching guides the user to speed up, slow down, warm up, and rest.
This project was a collaboration with a talented team of other designers, where I was in a design director role.
