Fans of Discovery Channel HD programming may be interested in the free Discovery app for the iPad (released March 2, 2011). Three days after the app’s release, its developer Bottle Rocket Apps announced that Discovery Channel HD was “the top free iPad app on the entire iTunes App Store.”

Features of the new app include chat sessions with show hosts and fans, images (including production stills), daily video clips, scheduling information, tune-in reminder alerts, science news, social interaction via Facebook and Twitter, and more.

The app is available at iTunes: Discovery Channel HD by Discovery Communications
