So, I don't know. I haven't had time to delve into their backend, so I'm not sure how they import all that data (lab results, ekgs, xrays). But the interface seems clumsy (coming from a former physician, and current ipad user) from the videos I watched.

Neither of the founders are from medical backgrounds: https://drchrono.com/team/

They do have a "Senior Medical Director" who is currently a psychiatry resident, which means relatively few years practicing medicine. I don't want to discount his abilities just for that, but for instance, it seems unlikely he has really worked in a private practice which is what this seems whole package seems targeted to.

I know disruption can happen from outside the system, but in the case of physician's medical record systems, I feel like the main hurdle is trying to show/teach doctors that your system can be a more efficient system in day-to-day. And to do that you really need to understand that day-to-day workflow. Especially since they are targetting these small practices it seems.
