Individuals' lifestyles manifest themselves in daily activities that can have effects that are a health-preserving, preventive or risk-enhancing, in terms of health. Some of them are simple everyday activities, as eating, exercising or smoking, which are closely related to health without being specifically viewed as health-related behaviours. In the case of university-age young people, a similar activity that affects health is the use of smart devices. Like any other factor, this can also have both positive and negative impacts on health. In this study, we looked at the health status of university-age young people, as well as their habits in using smart applications. The results have shown that the health of university students studying in Serbia and Hungary is satisfactory in several respects. In addition, several correlations can be seen between their general well-being, their exercise and eating habits, as well as their use of smart devices, applications, more specifically, applications aimed at health-care.
