Outside of optimizing health and fitness, the Charge 4 has practical advantages throughout the day, such as delivering smartphone alerts and notifications, playing music via Spotify, or paying for items with Fitbit Pay. It can track your time in light, deep, and REM stages to provide you with a nightly sleep score. Even when you’re asleep the Charge 4 is working. Based on your age and resting heart rate, it can tell you when you’re in the fat-burning, cardio, or peak heart rate zones. Working hand-in-hand with your fitness tracking is the built-in 24/7 heart rate monitor, which can track calorie burn and let you know when you’re in personalized heart rate zones.
