Fitbit Charge 2 Heart Rate + Fitness Wristband
Fitbit Charge 2 automatically tracks how long and how well you sleep and wake with a silent vibrating alarm. Aside from the sleep tracking function, this product also tracks your all-day activity like steps, distance, calories burned, floors climbed and active minutes. It is also important for every individual to keep calm. To track this moment, use this item that is equipped with personalized guided breathing sessions based on your heart rate. Fitbit Charge 2, like other heart rate trackers, its accuracy is affected by physiology, location of the device, and different movement.
