A great summary of dating behavior and apps across the world from the BBC. In Europe there is fierce competition between the two biggest apps here. Tinder dominates northern countries; Badoo is top in the east and south. In German-speaking countries, Lovoo - developed in the city of Dresden - is number one. The dominance of Tinder and Badoo does not extend to East Asia, where each country has a very specific preference. In China, Momo is trying to escape its origins as a dating app and become a social network.
