Glamour is the latest magazine from Condé Nast to introduce an iPad-iPhone app. Launching today, Glamour’s app follows a similar format to those already rolled out from Condé Nast Digital (including GQ and Vanity Fair) in that it offers the entire issue in a digital format, along with extras such as shopping pages that offer direct click- to-buy and extra photos. The app is launching with behind-the-scenes video of Jennifer Lopez by Ellen von Unwerth (who shot the actress for the cover) and exclusive Justin Bieber footage. “More women are starting to turn to the iPad,” said editor in chief Cindi Leive, adding that back issues will be posted and cost the same as new ones, at $3.99. The September issue makes it debut with nine “premium sponsors,” including Estée Lauder, A|X Armani Exchange, Ralph Lauren Fragrance, Levi’s and Revlon. So what’s next for future iPad issues? Leive wants to incorporate some kind of social-networking component to the application. “But that’s coming at a later date,” she noted. “We get 25,000 comments a month on glamour.com,” noting that she’d like to get some crossover to the iPad as soon as possible.
