MarvelComics has released a new iOS app called Marvel Unlimited in which includes subscription access to 13,000 comic books. For years, comic fans have asked Marvel to offer its digital subscription services on Apple’s iPad. Prior to today’s launch, they were restricted to reading back issues with an iOS-incompatible Adobe Flash-based reader. With iOS popularity, Marvel has worked diligently to make the app available. If you enjoy reading Marvel comic books then this app is for you!  Click here to get one via App Store anytime.
