The folks at Jackson Fish Market have handcrafted and personally tested, iPhone (and iPod Touch) apps to entertain and educate your tech-savvy little ones. Hippo Hooray Shapes, Colors and Letters are three separate apps available for just 99 cents each. Colors, shapes, and letters appear in a variety of contexts on colorful backgrounds with rich imagery. A young voice encourages the child towards the correct answer and then pats them on the back for a job well done. Each fun app has their own special cast of characters.
