Plenty of developers and publishers, not to mention Apple itself, are getting excited about the potential for children’s apps, whether education, entertainment or a combination of the two.

Apps Playground’s latest monthly roundup of the best iPhone and iPad apps for kids shows the variety of content being released for iOS, taking in well-known brands like Peppa Pig, Charlie Brown, Ben 10 and Chuggington; book-apps from the likes of Nosy Crow, Penguin and Disney; and kid-focused app startups like Toca Boca, StoryToys and Made in Me.

They join an already-crowded App Store, which makes two points. 1.) iOS continues to lead Android by some distance in terms of the effort and investment being sunk into children’s apps. But 2.) It’s a very tough place to rise above the clutter, even with Apple running more kid-app focused App Store editorial promotions.

There are some success stories – Duck Duck Moose’s 2.4m paid app downloads and Toca Boca’s 16m paid and free downloads most recently – and more investment coming into the space.

But there is work to be done in the way children’s apps are discovered (and marketed) to ensure the best examples don’t sink without trace on the App Store.
