Apple has released an official iOS app for its 2011 Worldwide Developer Conference being held in San Francisco next week. The WWDC app provides a mobile reference guide allowing attendees to access conference information from their iPhone, iPod touch or iPad. A session and lab schedule allows users to view all events, including lunchtime and evening events and search by technology, platform, session or lab. Users can also reserve time at selected labs from directly within the app, create a personalized WWDC schedule of favorite sessions and events and view detailed floor maps of Moscone West to find their way around. A conference news and photos section provides up-to-date announcements during the week and images from the sessions, labs and special events. The WWDC app is a universal app requiring iOS 4.2 or later and is available from the App Store as a free download.
