Microsoft Band is a new health and fitness tracker announced on October 29, 2014. The smart device officially goes on sale Thursday, October 30, 2014 for $199. Due to limited quantities, the device is only available in the US from Microsoft Stores and online.

The Microsoft Band is compatible with iOS, Android, and Windows Phone, and it works through a free, downloadable app called 'Microsoft Health'.

The Microsoft Band has ten sensors, and it can monitor things like heart rate, steps, and general movement including physical activities. Some of the novel sensors give you the ability to measure UV exposure and a galvanic skin response test to monitor stress. The fitness tracker lasts 48 hours on a single charge. You can wear it all day and night to track sleep as well.

The Microsoft Band comes with a 310 x 102-pixel touch display with 132 background options to choose from to personalize the smart device.

Other features of the Microsoft Band includes calendar alerts, email previews, 24-hour heart rate monitoring and guided workouts curated by Gold's Gym, Shape, Men's Fitness and Muscle & Fitness.

Windows Phone users also get Cortana integration for making appointments and reminders.

Finally, Microsoft also announced their new Microsoft Health platform, which works with UP by Jawbone, MapMyFitness, MyFitnessPal and RunKeeper. Microsoft Health will soon tie into HealthVault to share your data with your medical provider, should you choose to opt-in. Microsoft plans to expand their Health platform with a steady stream of announcements, including "additional device and service partnerships, SDK availability and other cross-platform applications and services".
