Continuous heart rate tracking helps you see how your heart behaves during your day. Together with Polar’s 24/7 accelerometer-based activity tracking it gives you a complete overview of all your daily activity. With continuous heart rate tracking all activity is counted towards your daily activity goal, even the activities where your arms are not moving, such as cycling. You also get even more precise calorie burn data. Your heart rate is tracked automatically with Polar’s wrist-based heart rate solution.
