The Niceboy WATCH GTR 2 smartwatch is equipped with advanced sensors that analyze your sleep progress and quality, as well as many other parameters. The watch also measures the most important health parameters including heart rate, blood pressure, blood oxygenation and more. Of course, there is continuous tracking of your activity, including a pedometer and an estimate of calories burned. And when you're sedentary, for example, you'll be reminded periodically that it's time to take a walk and stretch. You'll find more detailed stats and trends for all the metrics you measure in the mobile app, including the ability to set goals.
