Augmented Reality (AR) is a technology that allows the real world to be enriched or ‘augmented’ with digital content such as images, videos, sounds, and 3D models. This technology has become extremely popular and ubiquitous in mobile applications due to its ability to transform the way users integrate with the real world. The development of smartphones has enabled the development of numerous mobile AR applications. In this paper, the development of the mentioned technology from the very beginning is described, the impact on users is investigated, and predictions for the future are given. The most used tools for creating augmented reality mobile applications are also listed. Augmented reality plays a key role in improving the user experience in many applications and environments. Therefore, several (crucial) points on how augmented reality can contribute to a better user experience. Special emphasis is placed on virtual try-on applications. Virtual try-on is a technology used by many industries to improve the customer experience and make shopping easier when choosing products. In the practical part of the work, an application was created for virtually trying on watches, and the tools used were described.
