The Microsoft Band incorporates fitness tracking and health-oriented capabilities and integrated with Windows Phone, iOS, and Android smartphones through a Bluetooth connection.

[1] On May 31, 2019, the Band's companion app was decommissioned, and Microsoft offered a refund for customers who were lifelong active platform users.

[4] Production was ramped up in March 2015 to increase availability, several months after the release of Android Wear but ahead of the Apple Watch.

[6] The Microsoft band incorporates ten sensors, though only eight were documented on Microsoft's product page: The Band's battery was designed to run for two days on a full charge,[4][7] and the device partially relies on its companion app Microsoft Health, which was available for operating systems beginning with Windows Phone 8.1, Android 4.3+, and iOS 7.1+, if Bluetooth was available.

[8] Despite being designed as a fitness tracker, the Band has numerous smartwatch-like features, such as built in apps (called tiles) like Exercise, UV, Alarm & Timer, Calls, Messages, Calendar, Facebook, Weather and more.
