In relation to this item

During outdoor runs, rides, hikes, and other activities, use the app's built-in GPS to view your pace and distance on the screen, as well as a workout intensity map that shows your heart rate variations throughout your route.

Feel a tingle when you hit your goal heart rate zones during exercise, and celebrate when you earn extra minutes outside of activity with Active Zone Minutes.

To track resting heart rate and better calculate calorie burn, use heart rate 24 hours a day, 7 days a week. Bluetooth LE and an internet connection are required for syncing to mobile devices. Compatible with Mac OS X 12.2 and later, iPhone 5S and later, iPad 5th generation and later, and Android 7.0 and later.

In the Fitbit app, you can see your SpO2 nightly average and range on your wrist, as well as trends over the last week. (SpO2 isn't available everywhere.) The SpO2 function is not meant to diagnose, treat, or prevent any medical problem.)

Each night, keep track of your skin temperature to see how it differs from your unique baseline. (Not all markets have it.) Only in the Fitbit app, and it only shows variation. (This product is not meant for medical use.)

With 20+ goal-based training modes, you can keep track of your workouts in real time. It's also swimproof and water resistant to 50 metres, so you can wear it in the shower, track swims, and more.

When using the built-in GPS, the multi-day battery can last up to 7 days and up to 5 hours (varies with use & other factors). Track your sleep stages and check your Sleep Score in the app to see how well you slept.
