There is so much stuff to do and see in this app! The fact that you get a GPS zoo map, info on hundreds of animals, live animal cams (which appear to be working better), and extra fun stuff like the puzzles for less than the price of a paper zoo map is fantastic. Only minor complaint would be that the quality on the tiger and lion cams isnt as crisp as it is for the pandas.
