Software MacKiev has released This Day in History, an application specifically for the iPhone. The software is designed to leverage content in the 2007 World Book Multimedia Encyclopedia reference that Software MacKiev offers separately for Mac OS X users.
Free to bookmark and use on your iPhone, This Day in History is based on the same-named widget included with the 2007 World Book Multimedia Encyclopedia. The application offers you fun facts about the day’s date, automatically showing historical events that correspond to the current day.
Software MacKiev plans to offer more iPhone applications later this summer, including a companion application to its 3D Weather Globe & Atlas that will display wind speed, barometric pressure, dew point and other weather conditions; and the World Book Trivia Challenge, which tests your knowledge based on the World Book Multimedia Encyclopedia (and provides answers that include the name of the World Book article where more info is featured).
