You seem to be living in the past. While EHRs are still primarily used from desktop PCs, all of the major ones have native mobile apps now. Clinicians appreciate being able to review patient charts and action alerts while away from a PC cart.
And this would be a white-label Epic MyChart for the particular system with embedding for the inpatient or customer facing connections that should be used
It seems like that could be done with a system shipping their own white-labeled GNU Health app through the App Store
