Loopware today announced the release of iFlash 2.1, the latest version of the company’s flash-card style learning application. Version 2.1 adds the iFlash Deck Library, with which users can download many different card decks other iFlash users have made, as well as easily share their own creations. The Deck Library showcases many types of card decks iFlash users have created, from Japanese language studies to Eskimo snow terms, notes the Loopware. iFlash 2.1 requires Mac OS X 10.2.8 or later and is a free update for registered users — a new single-user license costs US$10.
