The iPad is a front end for https://drchrono.com which is a full SaaS product in its own right to manage all of the backend of the doctor's office.
We have a really good relationship with Apple, and we are one of the killer apps that make doctors go out and buy iPads. We launched on the iPad initially within a month of its release and work closely with Apple to make sure we comply with security and Apple standards.
So it is unlikely Apple will yank our app. We do have an Android phone application frontend and we can invest more in Android tablets as they evolve in the future.
