According to Forbes, Microsoft Corporation (NASDAQ:MSFT) is building a health tracker in the form of a smartwatch. The device will have sensors and would include technology and expertise from the Microsoft Kinect motion controller. The smartwatch will be compatible with Windows Phone, Android, and iOS, which is what distinguishes the device from other smartwatches on the market today. The smartwatch reportedly will be able to constantly measure heart rate throughout the day and night. And the battery will be able to last for around 2 days, which is about the same as the Samsung Gear Fit.
