They've done it, again. Duck Duck Moose has collected and sorted 103 words into seven different categories and delivers them, with help from Mozzarella and best friend Coco of course, in an iconic red wagon, in learning levels appropriate for preschool to Grade 1.

Levels throughout the categories (Animals, Food, Vehicles, Numbers and Colors, Around the House, Mozzarella and Coco's Favorites, All Words) begin with learning the names of the letters, move to learning the sounds the letters make, and progress to mastering spelling words with up to six letters. Self-propelled learning may begin with a game, but it's no joke. The app design takes touch screen technology seriously, and uses it to its age-appropriate best.

The lessons are charming, the rewards are sweet. Birds perching on a baguette, a sheep gripping a red balloon flies past the Eiffel Tower, Mozz talking on a banana phone, are just a few of the gags and giggles make the learning even more rich.
