The article describes the use of BYOD technology (Bring Your Own Device) in educational practice using the Lecture Racing mobile application. This application provides feedback between the teacher and students both in the classroom and during distance learning, contributes to the visualization of educational material and, in general, the informatization of the educational process. The purpose of the study is to conduct a theoretical analysis of the current state and prospects for the development of BYOD technology in Russia and abroad, and to test the benefits of using this technology in educational practice using the specific mobile application. During the study, an analysis of scientific, theoretical and practical literature on BYOD technology was carried out. In the process of experimental work, test tasks were the instrument of measuring knowledge and skills of students. As a result of a theoretical analysis and study of the practical possibilities of using BYOD technology (using the Lecture Racing mobile application as an example), it was found that this technology allows you to visualize information that is displayed in real time on the screen of each student's mobile device, regardless of its location. This technology also allows both the student and the teacher to quickly work with information, provide feedback, receive an independent assessment (since the assessment is set automatically), saves time, and develops the information culture of students.
