Here's a video that demos Epocrates Essentials on an Android smartphone:
Epocrates Essentials is our most popular drug and disease reference with content and features, including disease information, pill and disease images, over-the-counter drug and alternative medicine databases, and a lab interpretation reference.
The availability of the Epocrates Essentials content on the Android platform provides clinicians with convenient access to the critical information they need all on one device right at the point of care. The suite features cross-linking between the drug, disease and diagnostic content and can be used to support a patient consultation from diagnosis to treatment.
