Terrible
I downloaded this application because it was advertised in the zoo as a map of the zoo. The map was a caricatured version, making it indecipherable. It was unable to find simple exhibits using the search function such as "Zebra" or "Panda". Considering its an interactive map and should be easily updated to reflect changes in the park, it was extremely frustrating that it lead us to multiple food stands that were closed. Save your money and use the map on their website.
