The idea of this paper meaningfully revolves around the popularity and recognizability of social networks of mobile applications that have prevailed in people's everyday lives. Regardless of age and gender, today everyone spends time on various social networks, as evidenced in a survey of respondents about the readability of the user interface design of Facebook, Instagram, WhatsApp, Viber and Messenger. As part of this final paper, a survey was conducted among 145 respondents whose purpose is to examine the attitudes of respondents related to the design of user interfaces of various mobile communication applications. The survey offered answers that respondents selected selectively depending on which visual they found most enjoyable to watch / read or least enjoyable. The theoretical part provides an overview of the historical development of each individual communication network. The results of the survey indicate that respondents recognize social network logos, even people who do not use them. In the questions about visuals that are shown in different color combinations, the respondents chose the ones that are most comfortable to watch / read. Although it is individually easy to choose between Viber and WhatsApp mobile applications, in the survey, respondents chose WhatsApp, although research shows that Viber is number one in user selection.
