marvel digital comics unlimited
Marvel Unlimited is a new, native app front end for Marvel's Digital Comics Unlimited subscription service. It lets you read 70 years and 13,000 issues of back catalog comics -- Spider-Man, Iron Man, the Hulk, Captain America, Thor, Wolverine, the Avengers, the X-Men, Fantastic Four, etc. -- right on your iPhone, iPod touch, and iPad. That means you don't get the really new stuff -- you need a pay-per-issue app like Comics by comiXology to get almost anything from the last year -- but you do get an incredible amount of the classics.
