The JjComics Viewer interface is not exactly the best; actually, it's pretty ugly. In fact, you can't turn the page with a gesture swipe from left to right. Instead, you have to use a button on the side of the screen. Despite this, the app has several interesting customization options, including the ability to change the orientation of the page turn or to jump to the page you want.
Apart from its poor interface design, the fact is that JjComics Viewer is a competent comic reader with which you can read any comic from your Android device. It's certainly not the most complete reader of its kind, but it is one of the lightest by far.
Requires Android 2.0 or higher
