We talked with Jason Jacobs, Founder at Runkeeper, about the biggest challenges, trends and developments in health care technology at the Health 2.0 San Francisco 2011 Fall Conference.

Hardware that measures a variety of human activities is increasingly popular and transforming consumer engagement. People’s data is automatically being added to the Data Utility Layer from a multitude of devices, including updates from wearable sensors.

Jason made one of the first apps in the App Store and now Runkeeper has 6 million downloads with countless runners and bikers using it to track their work outs. But that’s just the start, Jason demonstrates RunKeeper’s Health Graph API, which takes data from mobile fitness tracking devices, puts it in one place and allows third party developers to build social or game functionality with the API.
