Best app & it's free
My 2 & half year old loves this app. There are no annoying advertisements & so many fun variations for my son to play with. It is the only app which he has been using for the past 2-3 months. He can't get enough. The only thing that could change is if the settings icon can be a bit harder to select, as my son goes in & changes the voice prompts & letter strokes as well as the voice recordings :-)
