With Fitbit Charge 4, there's no limit to how far you can go. This sleek, swimproof tracker is packed with features that help you know your workouts and your body better, such as built-in GPS, Active Zone Minutes, SpO2, exercise modes, and sleep tracking. Plus, with Fitbit Pay and up to 7-day battery life, you get more convenience on the go and more inspiration to reach your fitness goals.
The built-in GPS allows you to see your pace and distance on-screen during outdoor runs, rides, hikes, and more, and you can view a workout intensity map in the app that shows your heart rate changes along your route. With Active Zone Minutes, you'll feel a buzz when you reach your target heart rate zones during exercise, and you'll celebrate when you earn extra minutes outside of exercise.
The 24/7 heart rate tracking feature allows you to monitor your resting heart rate and better measure your calorie burn. Syncing to mobile devices requires Bluetooth LE and an internet connection, and the device is compatible with Mac OS X 12.2 and up, iPhone 5S and later, iPad 5 gen. and later, and Android 7.0 and later.
The SpO2 feature allows you to see your nightly average and range on your wrist, and you can view trends over the past week in the Fitbit app. However, this feature is not available in all markets and is not intended for medical diagnosis or treatment.
You can also track your skin temperature each night to see how it varies from your personal baseline, but this feature is only available in the Fitbit app and is not intended for medical purposes. It's also not available in all markets.
The Fitbit Charge 4 is also equipped with over 20 goal-based exercise modes, and it's swimproof and water-resistant up to 50 meters, so you can track your swims, wear it in the shower, and more.
Finally, the multi-day battery lasts up to 7 days and up to 5 hours when using the built-in GPS (with variations based on use and other factors). You can also track your sleep stages and review your in-app Sleep Score for an easy way to see how well you slept.
