Exploring the relationship between the use of exercise APP and the psychological mechanism of college students’ active exercise can help promote the formation of college students’ physical exercise habits and encourage them to participate in and adhere to physical exercise regularly. In this paper, 480 college students from some colleges and universities in Jilin Province were surveyed by questionnaire, and the data collected by questionnaire were calculated at multiple levels by multiple linear regression analysis and hierarchical analysis. The results of multivariate linear regression analysis showed that the loyalty of using the exercise APP had a greater impact on the ability motivation, appearance motivation and health motivation of exercise motivation compared to the trust, while the trust of the exercise APP had a greater impact on the social motivation and fun motivation. Conducting multilevel computational analysis, based on the results of the total hierarchical ranking, improving the reliability of data as well as enhancing the professionalism of the content are the most prioritized options for exercise APP operators to enhance the active exercise psychology of college students, with the weights reaching 0.278 and 0.272, respectively.
