In our testing, we found the Premium membership helped us make more sense of the data we collected, regardless of which tracker we used.īattery Life: 6 days (12 hours in GPS mode) We recommend getting it to utilize the most of your Fitbit’s features and receive more actionable recommendations for improving the health stats you’re tracking. (For example, one minute in lower HR zones counts as one AZM, while one minute of high HR activity earns you double.) Based on the American Heart Association’s guidelines, the default AZM goal is 150 minutes per week, but you can adjust yours according to your own goals.įitbit Premium Membership: This more advanced version of Fitbit’s free app gives you deeper insight to your health metrics. Monitoring SpO2 can provide insight to possible breathing issues, like sleep apnea.Īctive Zone Minutes (AZM): Calculated using your age, resting heart rate, and time spent in different heart rate zones, AZM give you a better idea of how much and how vigorously you get moving each day. A normal reading is typically between 95 and 100 percent but can vary based on age, respiratory health, and other physiological conditions. Oxygen Saturation (SpO2) monitoring: While you sleep, your Fitbit can measure and track SpO2, the level of oxygen in your blood. Complete a session by placing your entire palm on the device’s screen. Your result will indicate Normal Sinus Rhythm, Atrial Fibrillation, or Inconclusive.ĮDA (Electrodermal Activity) App: A two-minute scan measures your body’s response to stress by sensing changes in skin temperature and sweat gland activity. High HVR is generally considered an indicator of a healthy heart.ĮCG (Electrocardiogram) App: Place your thumb and forefinger on opposite corners of the Sense’s screen to perform a 30-second ECG and generate a report to share with your doctor. Tracking HRV can clue you into your body’s signs of stress, illness, and fatigue. Heart Rate Variability (HRV) monitoring: HRV is the variation in the amount of time between each heartbeat, measured in milliseconds.
