Sago Mini (a studio owned by Toca Boca and Spinmaster) keeps adding to their pack of excellent apps for younger children.This one is an excellent all-purpose starter app, which is excellent for preschool or ECE programs as well. 

Children choose from four structured activities that playfully reinforce matching, counting and music. Content is limited, but engaging and high in child control. 

You can dunk up to ten puppies in a tub to give them a bath, play fetch and work on shape recognition at the same time by matching toys, bones and socks for the puppies to play with. Sorting involves feeding pups donuts or pickles, and you can compose music on the the puppy piano. Manuel Afonso is the play designer for this title. 

Need to know: The app supports multi-touch, making it easy for one or more children to play together.
