Abstract: 【Purpose/significance】This study aims to analyze the adaptation model between technology and users from a two-way inter⁃ action perspective, and provide a reference for the transformation of technology from "technology in design" to "technology in use", so as to help technology designers provide technology services more effectively.【Method/process】This study selected 9 popular health APPs from the top 15 APPs in the free list of fitness and health APPs in the iOS APP Store, collected 1204 version update logs and 34148 user comments from 1 January 2021 to 30 May 2022. Using content analysis and qualitative comparative analysis methods, this study explored the adaptation model of health APPs and users.【Result/conclusion】The results suggest that there are three configura⁃ tions leading to the variance of APP ranking, and three adaptation models between health APPs and users.【Innovation/limitation】The innovation of this paper lies in proposing three adaptation models of users and technology, and discussing the updating strategy around the health APPs. This can be followed up with an in-depth study of the effectiveness and applicability of the models and updating strat⁃ egies.
