One of the great things about working on apps is that my daughter gets to play them. Though she's supposed to be a bit too young for this one (she's 1 1/2) she's mastered it already. She even seems to prefer the hardest game which is sorting trash. What can I say, she's a prodigy.
It really warms the cockles of my heart when we open up her folder of games on the iPad and she goes right to one I helped make.
