One interesting part about the app is the fine print.
There is a list of content that you cannot add to your comic in hopes of the app remaining kid and family friendly. It prohibits things like sexual content, drug use, guns, or revealing outfits.

Social issues, double entendres, amusement parks (other than Disney amusement parks), movie studios (other than Marvel) and sensationalism are also not allowed to be included.
