This app would be more fun if you could at least replace the dirty words with suitable replacements, like kumquat, but it would probably censor that as well. ;)

I read an example online. The real book read:

"If they don't think you're a person before sex, they won't think you're one after."

and CleanReader made it:

"If they don't think you're a person before love, they won't think you're one after."

Also apparenlty "breast" is a dirty word.

Women can chest-feed, and you can order a chicken chest sandwich.
