With letters to trace, puzzles to solve, and, of course, songs to sing along to, CoComelon invites little ones to play and learn alongside JJ and friends.

What we love: All the fun songs that accompany each activity. CoComelon classics like “Yes Yes Vegetables” are mixed in with traditional nursery rhymes (“Wheels on the Bus,” “Old MacDonald”), providing a toe-tapping soundtrack.

Quick tip: The Progress page lets parents see what their kids are loving in the app, including favorite activities, songs, and their most practiced skills.

Meet the creator: Founded in 2018, Moonbug Entertainment is also behind the kids’ brands Blippi and Morphle.
