In recent times, Badoo is the only application that has more singles even than Tinder. It is a dating application as well as a social discovery application, all in one. It is free to download and even to use.

However, you might need to pay some amount in order to unlock its premium features. This application is not only about swiping but it also helps you to discover people who are using the application near your location. Eventually, you can chat with these people too. This application has over almost 345 million people worldwide, so you can guess the number of singles using this app.
