Introduction In a scenario of continuous improvement of telecommunications network infrastructure and the maturation of related industrial chains, sports-oriented cell phone applications can meet the needs of different types of user groups due to their characteristics - close to the human body, able to collect users’ health, favorite sports, location, and other personal characteristic data in real-time. With the support of cloud computing, big data, and other techniques, the regularity of users’ sports health can be analyzed. Objective Explore the effect of obese college students’ use of cell phone apps on their exercise routines. Methods 53 obese college students volunteered for the research project. They were investigated by a questionnaire about their use of apps to aid exercise and health. Then, the participants’ exercise status was monitored, including weekly exercise time, exercise frequency, and exercise items, among other pertinent data. Finally, physical health data collected before and after the experiment were analyzed and statistically compared. Results Some obese college students did not acquire the habit of adhering to physical exercise, their psychological resilience and ability to fight frustration proved deficient, and the effect of an exercise assisted by cell phone apps left to be desired. However, for some obese college students who determined to exercise, the regular moderate exercise showed an improvement in physical health. Conclusion Exercise-focused health maintenance apps can stimulate obese college students’ enthusiasm for exercise, making the exercise process more enjoyable, controlled, and scientific. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
