What parents need to know

Ease of play

This app cuts right to the chase with knock-knock name and punch line
only, so there's no clutter of the standard lead-in lines ("Knock-knock,
Who's there?" and "____ who?"). It's easy to use: One touch of the "Tap Me!" icon makes a new joke appear. This simplicity means there is no way to search for specific jokes, save jokes, or sort by categories.

Violence & scariness
Not applicable
Sexy stuff

Nothing graphic, but joke punch lines include "Wait, her dress is unbuttoned," as well references to underwear and pants falling off.


Words like "stupid" and "darn" appear in some jokes.


Ads constantly rotate at the bottom of screen while users read jokes. A paid version of the app is also available; the paid version has no ads.

Drinking, drugs, & smoking

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.
