Maybe you could add a little detail about what you have planned. It seams a little optimistic that some apps will solve many healthcare problems.

I would like to see some more work along the lines of independent patient advocacy. It is tough, as a lay person, to know what treatments are available and effective (and other pros and cons). Also, navigating insurance, medicare, and other general healthcare related bureaucracy. Also, someone to answer simple health related questions would be nice.
