The Fit Bit Charge 2 HR Fitness Watch tracks every aspect of your active lifestyle, continuously measuring fitness sessions and daily activities. Like its predecessor, you'll find interchangeable bands for low-profile comfort and easy cleaning after sweaty workouts. The larger OLED display allows for tap navigation, allowing you to scroll through sub-menus with ease. Improved battery life lasts up to five days, depending on the activity settings used. Wireless syncing works harmoniously with Fit Bit's smartphone app, giving you in-depth analytical data of your workouts and daily activity. PurePulse technology measures changes in blood flow with a pulsing LED along the underside of the watch, translating these metrics into your beats per minute. Continuous heart rate tracking delivers a better picture of your personalized health with simplified heart rate zones providing indicators to dial fitness back or bump it up a notch. The Cardio Fitness Score (similar to estimated VO2 max) tests your cardio ability against cohorts in your age range, allowing you to visualize progress in your running performance over time. Another cool feature is the Connected GPS capability, which provides real-time running stats like pace and distance directly to your wrist, with a map of your route for post-workout viewing. Smartphone alerts deliver call, text message, and calendar notifications directly to your wrist, so you can stow your phone within a pack or back pocket. Another new feature is Guided Breathing, which measures your heart rate for personalized relaxation with deep breathing exercise. The FitBit Charge 2 is compatible with both iOS and Android devices, alongside Mac and Windows computers with the provided wireless dongle. Also, it comes with a charging cable for powering it from your computer or USB wall charger.
