Mobile fitness app is a new product in the Internet era, which provides convenient fitness help for sports enthusiasts. The purpose of this study is to explore the influencing factors of users' long-term willingness to use mobile fitness App-Keep, and to produce a design guide for the design and marketing of Keep. Based on the Expectation confirmation model of IS continuance (ECM-ISC), this study combines the important variables of the Technology Acceptance Model (TAM) and the Expectation Confirmation Theory (ECT), and then combines the characteristics of Keep app, constructs a model that affects its continuous use intention, and then makes statistical analysis of the questionnaire data. Verifying the influencing factors and mechanism of user stickiness does not lead to the following conclusions: (1) The perceived ease of use of mobile fitness application Keep has a positive impact on perceived usefulness, while the perceived ease of use has no significant impact on user satisfaction; (2) Perceived usefulness, perceived interestingness and perceived quality have a direct and significant impact on user satisfaction, thus enhancing users' willingness to continue using; (3) Perceived usefulness plays a complete intermediary role in the relationship between perceived ease of use and satisfaction, while it plays a partial intermediary role in the relationship between perceived interest and satisfaction. In this paper, a conceptual model of user stickiness in mobile health applications is constructed and verified theoretically. The practical level provides product strategy tips for Keep app and even all mobile health applications to form better user stickiness.
