RunKeeper's Health Graph integrates fitness sensor data, such as GPS trackers, Wi-Fi body scales, sleep monitoring devices and heart-rate transmitters, with eating habits, workout schedules, social interactions and more to help users track and understand their health and fitness choices in a holistic, highly correlated manner.
RunKeeper's apps for iPhone, Android and Windows Phone 7 can help users understand how their social habits affect their sleep and workout patterns, which in turn affects their health.
Now device manufacturers and app developers -- including launch partners Foursquare and Zeo -- can tap into this same data, as well as RunKeeper's social features, like its FitnessFeed and sharing integrations with Facebook and Twitter. Founder Jason Jacobs explains the API in a blog post.
