iOS8, Health Data, and Open Data

News is leaking out of Apple that iOS8’s primary feature will be health and fitness data. Rumors are that there will be a new app called Healthbook that will track a plethora of health and fitness data that iPhones and related devices (iWatch?) will be able to collect on the person carrying the devices.

This is interesting to me on a number of levels. We have been looking at this sector for a while and one of the things that has kept us (USV) from making investments in this space is the sense that all of this data capture is soon going to happen in the phone itself.

Once that happens, things can change pretty rapidly. The key will be APIs. And my big question is whether Apple will give its users an open API to send their health and fitness data to third parties they authorize.

I can see a button that says “auth with Healthbook” in my doctor’s office, my gym’s mobile app, my health insurers’s web app, and a host of other places.

So to my mind, the big question is not what Healthbook will look like but whether Apple will make it easy to get our data out of it. If they do, this will be a massive game changer for the quantified self, health, and wellness markets.
