Tons of Sesame Street videos from the show plus mini-games that engage kids interactively in a way that videos just can’t achieve on their own combine to make this app almost as good as watching the show. The only thing missing is the overarching storyline to tie everything together. You can search by favorite character or browse through collections of 8 different “learning areas” such as literacy or emotional development. There are plenty of celebrity appearances and the signature Sesame Street humor. Bottom line: if you’re okay with (or big fans of) Sesame Street, you’ll love this free app.
