Improve your energy levels
The Energy score is the ultimate score that tells you how much energy you have accumulated for the day. It is made up of many night and day markers so that you can evaluate your vitality and know every morning if you can surpass yourself or if you may avoid intensive activities and focus on rest.
Data you can count on
Circular calculates your energy levels based on many physiological contributors: Physical Activity, Sleep, Heart Rate Variability (HRV), Resting Heart Rate (RHR), temperature variation, Blood Oxygen Saturation and Breathing Rate. These metrics are calibrated to your baseline, which means that your score is personal to you.
Data driven training
Getting the most out of training doesn’t always require working harder: it requires working smarter. Quantify your physical activities and optimize your effort with heart rate training range.
