Health Cloud is not developed by Google. Rather it uses Google Health's publicly available API (the Objective-C GData libraries) to communicate with Google's servers to retrieve a view of the PHR in the form of a Continuity of Care Record (CCR). The XML-based CCR is then passed through an XSL stylesheet developed by The American Academy of Family Physicians (AAFP) and displayed on your iPhone's screen.The developer notes that a new version of Health Cloud has been submitted to Apple for approval. The new version adds the ability to display additional health data, as well as notices from health care providers. The update also improves the format of the displayed health record.
Pre-orders and previews begin April 10, launches April 24.
