For better or for worse, modern American romance is all about apps. We look at a photo, maybe read a quick bio, and then swipe left or right to signify our interest. The pervasiveness of app culture in the United States led us to wonder if people in other countries also rely on dating apps. Is the rest of the world swiping as much as we are? And what are some of the most popular international dating apps? You might be thinking, they probably just use Tinder everywhere. In addition to the U. One of the even more commonly used international dating apps is Badoo , which has over million users. Like Tinder, Badoo was based on swiping until recently, when the company got rid of swipe-based matching and debuted a new live video feature.
