Scanadu is sending your mobile phone to med school, creating a consumer medical Tricorder.
Healthcare is rapidly becoming quantitative, a number's game. Patients as well as doctors will be overloaded with "big" data. This will open up a massive market for auto-diagnosis. But this market needs a tool, just like the mobile market needed a mobile phone.
The tool will be the Tricorder, putting a doctor at the fingertips of millions.
