It was last year when Bonnier released their “Mag+” concept video, showing an impressive prototype magazine for an iPad-like device.  Only 90 days later, they’re back with an official iPad app to bring this concept to life with Popular Science+.

Popular Science+ is a new way of experiencing magazines on digital devices and a first step toward our vision of what digital magazine reading can be. Mag+, Bonnier’s digital magazine platform, is a project that began months ago in a collaboration between Bonnier’s global R&D task force and BERG, a London-based design studio.

Our goal has been to preserve all the qualities that make magazines such a powerful, popular medium—inspired packaging of carefully curated content by a team of expert editors, delivered in a visually dazzling issue with a beginning, middle and end—and at the same time to reinvent it in a way that makes it come to life on the iPad’s screen.”

You can read more about it in the Bonnier Beta Labs, and get the app via iTunes ($4.99).
