While the Apple Watch has only been available a short time, there are already thousands of apps available for it. Iltifat Husain, MD of iMedicalApps, has found that only 13 of the current apps are designed for physicians. One of them is Vital Values, an app that gives normal vital signs for pediatric age groups. The other apps include various medical calculators and communication apps.
However, keep in mind that iMedicalApps also notes that wearing Apple Watch when caring for patients may be unprofessional.
