Best free CBR and CBZ readers for Android

More and more people are getting acquainted with classical and new comics, and now it is easier than ever thanks to the digital publication. One can buy the new issue as soon as it is available online or download some old issues for free from the public libraries. And, of course, users need good tools for reading those comics.

Digital comics are issued in CBZ and CBR formats — these are ZIP and RAR, just used exclusively for comics' pages. These unique extensions are implemented to let know that the archive contains comics pages (images in high quality) and that these files should be open by a special software. As CBR and CBZ are archives, they can be treated by the standard archivers, and any standard image viewer can display the pages.

However, it would be more convenient to have the edigital equivalent of a paper magazine with the option to scroll the pages and use bookmarks. Besides, comics lay on the visual side, and the device should be able to present the colors and have the screen of a suitable size.

Thus, CBR and CBZ digital comics belong to the sphere where e-ink ebook readers lose to reading apps for smartphones and tablets. There are free CBZ and CBR readers for different mobile OS, and the widest variety is in Android reader apps which you can install on your mobile phone or tablet and enjoy your favorite stories.
