You can detect and manage stress, as well as know when your heart rate is abnormally high or low. You can even track your skin temperature and keep an eye on patterns. You can monitor your heart rate while you're exercising or resting, perfect for keeping track of trends. PurePulse 2.0 is Fitbit's most advanced tracking sensor yet. Sleep peacefully with the sleep monitoring - it can tell you all about your sleep stages and sleep scores, and wake you gently with silent alarms. When you get your Sense, you'll get 6 month's free trial for Fitbit Premium - that means access to fitness and nutrition programs, even more health insights and more tools to help you stay fit and healthy. You'll be able to track your fitness with the Sense. It tracks your everyday activity, including steps, distance and calories burned, with a built-in GPS that helps you track your pace and distance even when you don't have your phone on you. When you hit the gym, it can also help you to make sure you're staying in the zone with active zones minutes. It uses your resting heart rate as a baseline and helps you to see how your efforts are adding up. This smartwatch is water resistant too, which means it can join you for a swim. There are more than 20 exercise modes, and SmartTrack is there to automatically recognise the exercise you're doing.
