My sources tell me instead that Microsoft will this fall release a Samsung Gear Fit-like fitness band that will display smart phone-based notifications, just like the current and rumored watches and other wearables. So that's the first bit of rumor busting: It's a wristband, not a watch. (Yes, I'm sure you'll be able to see the time on its screen. But the form factor is a wristband.
Microsoft's fitness band will reportedly have the ability to sync with multiple platforms including Windows Phone, Android and iOS. Samsung wearables only work with Samsung devices and Android wearables only work with Android devices -- but it seems Microsoft is taking an alternative route and having its wearable work with all platforms.
Microsoft's wearable will be able to track your fitness such as steps, calories burned, heart rate, and then relay that data to the smartphone through an app. No word on whether or not it will support iOS 8's Health app that will launch this fall.
The fitness band will reportedly be announced and sold during the fourth quarter of 2014. It will be priced similar to the Samsung Gear.
