A cloud service from Microsoft for storing health data from fitness devices and apps and offering insights from its Intelligence Engine that help people lead a healthy life. For example, people can learn how much deep sleep they get, which exercises burn the most calories and how long they need to recover before working out again.
Although Microsoft encourages third parties to integrate their wears with Microsoft Health, they also make the Microsoft Band fitness device. See fitness tracker
