Kinect PlayFit launched today on Xbox LIVE as a free download for all Xbox LIVE members in the US. It will be launching outside the US later this week.
Kinect PlayFit is a new fitness dashboard that aggregates and tracks the calories you burn as you play a variety of Kinect games, from "Dance Central 2" to "Your Shape Fitness Evolved 2012" to "Kinect Star Wars."
It lets you view your personal stats over time and see leaderboards that show how you rank against Xbox LIVE members across the globe. Youo can get credit for the calories you burn while having fun with Kinect, and earn Kinect PlayFit Achievements, Gamerscore and Avatar Awards.
