With the advancement of mobile technologies and the growth of user demands, the process of designing mobile applications is becoming increasingly sophisticated and dynamic. The design of mobile applications is becoming more complex, taking into account various aspects such as functionality, intuitiveness and adaptation to different user needs. This progress reflects the necessity for continuous improvement to ensure an optimal user experience and the efficiency of application use in a dynamic digital environment. At the same time artificial intelligence is becoming ubiquitous in various industries, opening new doors for innovation in design practices, including mobile application design. This study explores the challenges of applying artificial intelligence in the design of mobile applications and includes a comparison of conventional design methods with the use of artificial intelligence tools. The experimental part encompasses the mentioned variations of the design process, which were evaluated by experienced UX/UI designers. Based on the obtained results, it is concluded that artificial intelligence, in its current form, can be a useful tool in certain stages of the mobile application design process, but is not a substitute for human creativity and expertise. The paper also opens perspectives for further research to delve deeper into ways to enhance the application of artificial intelligence in mobile application design, particularly regarding innovation and personalization.
