**As published in digiday:DAILY** Publisher: Paragon Technologie GmbH Price: $24.99 Platform: iPhone/iPod Touch Advertising: None Functionality: C- Fun Factor: C Overall: C Any app priced at $24.99 is going to be a tough sell. But once a publisher crosses that hurdle, it should strive to deliver a better-than-expected experience. Keeping that in mind, it’s still hard to see how any reference app like Encyclopaedia Britannica could exceed expectations in any environment, let alone mobile. There’s certainly nothing evolutionary or revolutionary in this new app, but it at least gets close to delivering on expectations. The value of any reference app on mobile is purely based on its convenient format (read: digital) and its content that’s been thoroughly vetted by academia. Wikipedia might have more name recognition than Britannica at this stage of the game, but the weight that Britannica carries as a solid resource won’t be bested by Wikipedia anytime soon (if ever). Valuable content aside, the eventual success of this app will depend on whether or not a worthwhile number of users subscribe to that idea so diligently that they are willing to cough up $24.99. My best guess is probably not.
