With hundreds of connected self-monitoring devices and a rich developer API, Microsoft HealthVault is the ultimate platform for Quantified Self hackers, or for that matter anybody interested in being an active part of the future of healthcare.

Until now, though, using that API on your own has been a bit tough because of the requirements and process involved in connecting an app to our production systems. There are good reasons for these gates in general --- but hey, it's your data, right? Enter the Personal App Manager. This tool lets you create as many applications as you like, connected to our productions systems, but that can only be used with YOUR information. You write what you want, you do what you want.

We're really excited about this, and can't wait to hear what kind of awesome stuff you do with it. Enjoy!
