This might come as a surprise to many, but after you use this prescription medical reference app you’ll understand why it ranks so high. The overall user interface of the app is simple and quick. There is minimal clutter — another reason for such a high ranking. If you need to look up a dose or some quick reference information about a drug you can accomplish this with ease, as shown in the below pictures. There are no prompts to register your e-mail address, no CME activities, no icon badges, no notifications, or any other distractions. The one knock on this app is it doesn’t have a robust drug interaction checker, something Medscape and Epocrates provide. On the flip side, for residents and medical students, the app does a better job than other drug reference apps when it comes to mechanism of action information and patient teaching information. Another plus is it’s available for the iPad — which is not true of Epocrates and Medscape. The application is a production of Thomson Reuters, a legitimate name in Healthcare.
