To use the application, logically, you will first have to create an account with the service, including a profile in which, in addition to your picture, you will have to indicate what your likes are and what exactly you are looking for.
Once you have done this, all that is left is to either wait for someone to contact you or look among the rest of the users for someone that interests you. You can filter by location, likes, age, etc. Thus, finding your ‘better half’ will be much easier.
Using Badoo is completely free, but there are many features to the app that cost money. One of the most popular of them, for example, is one that allows your profile to stand out among the rest of the other users of the social network.
