Stay connected while tracking your all-day activity and exercise with the large, black Charge 2 Fitness Wristband from Fitbit. This wrist-worn activity monitor tracks how many steps you take, your distance traveled, calories burned, floors climbed, and how many minutes you stay active. Thanks to its onboard PurePulse technology, the Charge 2 also provides continuous and automatic heart rate data. You can use this heart rate data to monitor your intensity, analyze the effectiveness of your activities, maximize your workouts, and more-all without the need of an additional heart rate chest strap or accessory. Additionally, the Charge 2 features SmartTrack technology that automatically recognizes the exercise your performing and records your metrics to the free companion app.
The Charge 2 houses an OLED display that lets you see your progress in real-time throughout the day. In addition to fitness tracking and heart rate data, the Charge 2 can receive smart notifications from your smartphone, so you can stay connected to the outside world even when you're working out.
You can sync all your Charge 2 stats wirelessly to compatible mobile devices and computers. Simply download the Fitbit app to sync with a smartphone, which is available for iOS, Android, and select Windows devices.
