According to a on iMedicalApps, the premium version of Epocrates is free for medical students if they download it BEFORE August 31, 2010. There are some caveats to it, students must have an iPhone, iPod Touch, Windows Mobile, or Blackberry. And to those who are using Androids or PalmPre’s, “No soup for you!” You are out of luck because there isn’t a premium version available to those phones.
The premium version of Epocrates is normally $159. Medical students must register by creating an Epocrates account and then selecting the medical school.
