The HealthVault team has recently added the capability to write applications that will run on Mobile Devices and connect directly to the HealthVault Service. HealthVault iOS library enables developers to write iOS applications which interact with a user's personally controlled health record. The “go live” process to deploy an application against the production HealthVault service can be found at http://msdn.microsoft.com/en-us/healthvault/bb962148. Information about the API that the HealthVault service exposes can be in the documentation in HealthVault .NET SDK. - View it on GitHub
