comiXology’s iPad/iPhone comic book reading apps dominate the e-comic book space. comiXology provides the comic book reader and in-app purchasing mechanisms for the branded apps from DC, Marvel, Image and others. The on-screen reading experience is very good. And, in-app purchases are simple. The only common criticism is the price of the digital comics which are mostly $1.99 per issue.

comiXology’s latest comic book app focuses on titles for young children.

Comics4Kids

As with their other comic book reader apps, Comics4Kids is a free app with over a dozen comic book publishers provided content for in-app purchase. The list of publishers includes Archie, Image, and Shadowline. While most of the mainstream comics books from publishers like DC and Marvel are priced at $1.99, many of the issues in Comics4Kids are priced at 99 cents. The most notable missing publisher of kids comics is Disney.

There are a number of free issues and preview issues (incomplete or summaries) that can help you familiarize yourself with the app before commiting to in-app issue purchases. It may be just the thing to help the kids in the backseat settle down for the long drives and airplane rides this summer.
