Dating apps were created with the development of the Internet and the development of smart mobile phones, and in a short period of time they became one of the most popular ways to find potential partners. The search for romantic partners, outside of social circles and neighborhoods moved to the Internet and applications, and today that market has developed into an industry worth a billion dollars. Identifying factors that can increase an individual's likelihood of finding a partner (and thus possibly having children) is of great importance at both the individual and societal levels. The most popular application for meeting potential partners is Tinder. In this paper, we deal with the differences between the sexes on applications for meeting partners, the motives for using applications, the impact of the abundance of choices on decision-making. In the empirical part of the work, we investigated the motives for using applications, the differences between the sexes in the motives for use, which gender is more likely to initiate conversations on dating applications, what are the most important criteria when choosing potential partners, and was there an increased number of the of sexual relations using dating applications. The data showed that the most common reason for using a dating app is to create long-term relationships, men are more likely to initiate a conversation on dating apps, physical appearance is the most important criteria when choosing a partner, and the use of dating apps in more than 50% of cases does not increase the number of sexual relationships. Given that the sample is specific and small, it is difficult to draw general conclusions, but the paper offers a basis for further and more detailed research on the subject of meeting potential partners via the Internet.
