2. Epocrates

As we reviewed in February, the free version of Epocrates is considered by many to be an essential drug reference. Useful and easy-to-learn features like the pill identifier, several medical calculators, and drug interaction checker make Epocrates a favorite of clinicians and students alike.

Of note, Epocrates recently announced support for the premium versions of Epocrates on the Android platform.

As with other popular and new Android apps, Epocrates is not available for Android users with older operating systems (version 1.5 or older).
