Smart Rope is the next step in the evolution of the jump rope. The jump rope connects to our app via bluetooth to tell you about your cardio exercise. The app keeps track of workout data: jump count (records each complete revolution of the rope as a complete jump), monitors calories burned and time spent jumping. Jump Rope helps make your cardio workout even more effective with accelerometer sensors that counts your jump and the display the results via the app. Train your body, track your progress and improve your stats.
