Each human being on this planet is unique and comes with different customs and cultures. Customs differ from one city to another so just picture the distinctions between one country to another. The application comes with all kind of useful information for 165 countries. Whether you’re looking for tips for your future destination or simply want to improve your geographical knowledge, World Customs and Cultures surely comes in handy.
The user can check out Greetings, Communication Style, Personal Space and Touching, Eye Contact, Views of Time, Gender Issues, Gestures, Taboos and last but not least Law and Order. Even Personal Space and Touching is quite important so the traveler must be informed of specific gestures or customs that might offend the native one. 
What captured our attention was the fact that the application comes with a GPS if one is lost and wishes to know exactly where he is. There is also provided a Random tab that offers random customs for those moments that you simply don’t know how to deal with time. 
Just an FYI. For some reason the iTunes store says this app is not available in the US at the moment. I love the app and wanted to share it with some students going abroad.
