Looking for a comic book reading app for your iPhone or iPad? Apple has taken care of the legwork for you and assembled 10 featured apps in their Comics section.
iTunes App Store Comics Section
If that 10 count seems a bit low, it is. Scroll down a bit more to see an additional 15 apps that are bit more specialized. This second group features, for example, the Star Treks Comics and Transformers Comics apps (both free).
Comics apps generally feature in-app purchasing to buy new comics. Be sure to keep an eye out for free issues too.
