Visitors have access to information and videos for a number of species anytime and can check where to find a particular animal. Zoo-Tours prepared for different interests and occasions are also presented on the phone. “We have installed so-called beacons at selected animal enclosures,” the zoo’s Social Media Manager, Tobias Grüter, explains. Powered by the existing beacon technology as a way to offer location-based information or advertising the app uses small transmitters that send a signal to the phone when the app is on. Berlin Zoo is one of the biggest in Europe, with more than 20,000 animals. If you search for “Zoo Berlin”, you will find the App for download for free both in the App Store and Google Play Store.
