Online dating apps are an easy and popular way to meet potential romantic partners. Since young people are almost always connected via mobile phones, such applications are easily accepted. How intimate relationships have changed and how technology has affected this will be part of this paper. Starting from the theoretical concepts of Zygmunt Bauman, Anthony Giddens, Aaron Ben-Ze'ev, this research focused on the experience of using online dating applications, and how it is related to the perception of intimate relationships and the level of religiosity. An online survey was conducted on a sample of 142 students at the University of Zadar and tried to find out more about students' general thoughts about dating apps, their motives and frequency of use, and their attitudes about intimate relationships and religiosity. It was assumed that respondents from larger cities would use the applications more often and that their opinions about them would differ. With regard to attitudes about intimacy, a difference in use and level of religiosity was also assumed. The results of the research showed which applications are most used, motives and frequency. It was further shown that there is no statistically significant correlation between the size of the settlement in which the respondents grew up and the use of online dating applications as well as opinions about them. However, it turned out that there are statistically significant differences in respondents' attitudes about intimacy with regard to non-use and religiosity, and there was a weaker negative association between the use of applications for casual sex and fear of connecting with others.
