Kids say (1 ):

KNOCK-KNOCK! is a simple, fun app for kids who are going through that "knock-knock" phase to learn some mostly harmless new jokes. Knock-knock jokes help kids understand puns, so you might even call this app a tiny bit educational, although it is meant to entertain -- and includes some creative spellings (or misspellings). The ads at the bottom of the screen -- for apps mainly geared toward adults -- seem unfortunately mismatched to a young audience. No ads on $.99 version.

Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
