Awake or asleep, the Fitbit Charge 4 Health & Fitness Tracker is designed to provide you with all-day health and fitness tracking. Featuring built-in GPS, the Charge 4 lets you see your pace and distance when exercising outside, along with a map of your workout. It tracks runs, rides, and hikes, but the Charge 4 is capable of much more than that. Over 20 goal-based exercise modes are at your fingertips. Simply go into an exercise mode during a workout, set a goal, and then see real-time process on screen.
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. 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. Even when you're asleep the Fitbit Charge 4 is working. It can track your time in light, deep, and REM stages to provide you with a nightly sleep score. Outside of optimizing health and fitness, 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.
