The best reader for all the reddit f7u12 rage and Advice Animals comics. This app background loads comics, so they are ready when you are. Ever try to load another app in class or where you have no signal? Challenge accepted--this app reads from your cache, so no worries. Try this with any other rage comics app and you will see the difference. Install this app and another, pop your device in airplane mode, and watch what happens.
