Comic Book Viewer 4+

if you’re looking for a simple, easy-to-use comic reader with enough features to give you some extra bells and whistles, my App should probably be your first stop.

The interface has a basic library function, but it’s easier to simply open your files (CBR, CBZ, and PDF, among more pedestrian image formats) directly from your computer’s file explorer (Finder). The reading view makes it easy to find your page with thumbnails along the thumbnails view, and various fit modes along with a full screen view are handy in both button and hotkey flavors. The reader supports double-page views to best emulate comic reading, and a right-to-left mode for those who prefer manga to western-style comics.
