This is a prime example that apps don’t need to be complicated to be entertaining. You can download the free version of this app, and then upgrade for $1.99 for more variety. The basic premise of the app is that kids just swipe through different cards to learn the names of the item pictured. If it’s an animal, you also get the added bonus of the animal sound! There are tons of words they learn that you may otherwise not say on a regular basis.
