Encyclopedia Britannica

Known as the definitive encyclopedia app for the iPad, Encyclopedia Britannica for iOS provides effortless access to the full range of Britannica’s archives. The app features LinkMap, a visual linking system designed by Concentric Sky to facilitate the browsing of large interconnected article collections.

The success of this award-winning app facilitated Encyclopedia Britannica's switch to a purely digital sales model.

Concentric Sky also designed and developed Encyclopedia Britannica's award-winning line of K-6 products, EB Kids. This series of apps for iOS, Android, and Windows were recognized by Apple as among their "favorite apps for learning” and were featured prominently as part of the launch of the iPad 2.
