Each since it was released, Apple has made noticeable strides to improve the built-in Health app. It launched on iOS 8 where we saw Apple promote HealthKit enabled apps, then with iOS 9 we saw the expansion to new health data points. iOS 10 takes Health a step further by now allowing users to store their health records directly in the app using the Health Level 7 Continuity of Care Document (HL7 CCD) standard. No longer having to track paperwork or use CDs, these health records will be tracked directly in-app with the ability to be imported from Mail, Safari, and other applications.
