Looks like Rolling Stone is now ready to settle and gather some moss on the iPad. And by “moss” I mean subscription dollars.

If you’ll recall, in May 2011, Rolling Stone publisher Jann Wenner dismissed the rush of other magazines to migrate to the iPad as “sheer insanity.” Well, it appears that Wenner has finally embraced this sort of insanity with the release of the official Rolling Stone Magazine app for iPad.

Available now as a Newsstand app, Rolling Stone Magazine is the latest high-profile publication to enter Apple’s digital newspaper and magazine platform. Just a couple of weeks ago, Forbes Magazine launched on Newsstand. And a couple of weeks further back, so did The Wall Street Journal.

As the official native iPad version of the popular publication devoted to music, politics, and popular culture, the new Rolling Stone Magazine app offers …

… all the breaking music news, hot album and movie reviews, must-read rock star profiles and in-depth national affairs reporting you love in the magazine. Plus […] exclusive photos and instant streaming samples of the best new music in the world.

Rolling Stone Magazine

Within the app, you can buy a single issue for $4.99. Or you can opt for a one-month subscription for $1.99 or a one-year subscription for $19.99.

Note that either subscription option comes with a one-month free trial period, after which the payment for your purchase will be charged to your iTunes account.

Note too that, unfortunately, an existing print subscription entitles you to neither a free digital subscription nor a discounted one.

Compatible with iPad running iOS 4.3 or later, Rolling Stone Magazine is available now as a free Newsstand app.
