If you have an iPad and you love comics, here is a must have app for you. Comic Viewer is an iPad app, which allows you to browse and read electronic comics.
Comic Viewer supports almost all the general image file formats (such as JPG, PNG, and GIF), as well as CBR and CBZ Comic Archive Formats.
Here are the snapshots of Comic Viewer from official app download page.
The fact that it doesn’t support PDF files, is a setback, but Comic Viewer costs $5 which is pretty cheap as compared to other reader apps. You can read a detailed review of Comic Viewer @ Gizmodo.
