This is a really cool app visually. It's kind of 3-d and the app tilts with you when you tilt the iPad/iPhone. The photos/pictures are nice. There's plenty of animals to see and each page says something "if you were an animal living in a zoo would you want to be yellow, red or blue?" I really like that when you touch the animal, it says what it is "wolf" and when you touch it again it makes the sounds of a wolf. My 2 year old easily navigates through the pages with the arrow buttons. Overall, worth the price. I've purchased all three apps.
