Apple Watch is designed to help anyone who wears it lead a healthier life by being more active. From people who just want to be more active throughout their day, to those who work out a few times a week, to athletes committed to improving their performance. Apple Watch brings together the capabilities of an all-day fitness tracker and a highly advanced sports watch in one device you can wear all the time. It can track a wider variety of activities because it's able to collect more types of data. It uses an accelerometer to measure your total body movement. It has a custom sensor that can measure intensity by tracking your heart rate. And it uses the GPS and WiFi in your iPone to track how far you've moved. We wanted to give you the most complete picture of your all-day activity, and not just highlight the quantity of movement, but the quality and frequency, as well. So the Activity app on Apple Watch measures three separate aspects of movement, with a goal of helping you sit less, move more, and get some exercise. The Move Ring measures the calories you've burned-- that gives you the best overview of how active you are. The Move Ring is customized to you, and you close it when you hit your personal calorie goal for the day. The Exercise Ring captures the brisk activity that you've done.
