The parents' guide to what's in this app.
What parents need to know
Parents need to know that Knock-Knock! supplies kids with a stream of knock-knock jokes, all at the tap of a finger. The "dirtiest" jokes you'll find here go something like: "Knock, knock," "Who's There?" "Champ." "Champ Who?" "Champ poo your hair. It's dirty." Small ads appear at the bottom of the screen in the free version. No ads in the paid version also available in the App Store.
Is it any good?
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.
For kids who love to laugh and play with words
