I like finding such programs on the internet because my son loves using them on his Ipad. It was shocking to me because I thought he would only play some kids' games and watch cartoons there. I'm glad that he likes to learn something new, so I usually buy him some educational toys from kickstarter, and that's all he needs to be happy. And with the purchase of an Ipad, he started spending more time learning, and sometimes I can't believe he's only five and not twelve, to be honest, and I wonder if he's going to like school.
