Put any three doctors in a room together, though, and you're likely to get three different opinions.

Dr. Kurian Thott has an almost diametrically opposite approach to medical app development than Levine. Thott, physician and Chief of Women's and Children's Services at in Northern Virginia, is a firm believer in letting the market sort out which medical apps will succeed.

Adding regulations from the FDA "will be amazingly difficult," Thott said. "It will put a monkey wrench into the app development process."

And Thott knows a thing or two about app development. He's the originator of the aforementioned iRounds app, a tool that helps a group of physicians communicate better when one doctor hands off their on-call status to the next doctor in the rounds rotation.
