Background/Objectives: Mobile health applications are essential for improving healthcare access and promoting healthy lifestyles. This study investigates the roles of perceived ease of use, usefulness, and satisfaction in shaping behavioral intentions using the Technology Acceptance Model. Methods: A survey of 329 mobile health application users in Korea was analyzed using confirmatory factor analysis and structural equation modeling to test hypothesized relationships. Results: The findings indicate that perceived ease of use positively influences perceived usefulness (H1). Customer satisfaction is positively influenced by both the perceived ease of use and perceived usefulness (H2 and H3). Furthermore, behavioral intention is affected by perceived ease of use, perceived usefulness, and customer satisfaction (H4 through H6). Conclusions: The findings from this study elucidate how mobile health applications can enhance users’ perceptions of ease of use and usefulness, thereby influencing their behavioral intentions through increased satisfaction. This research also advances our understanding of application services and informs the development of effective operational and marketing strategies.

Background/Objectives: Smartphone-based leisure reservation platforms increasingly shape how individuals participate in leisure, yet little is known about how such technology-mediated engagement influences users’ awareness of multidimensional health benefits. The purpose of this study is to investigate how regular users of smartphone-based leisure reservation platforms perceive multidimensional health benefits associated with their leisure activities. Methods: Based on a constructivist/interpretivist approach, this study applied Interpretative Phenomenological Analysis (IPA). Ten participants with at least one year of platform use completed semi-structured interviews. Data were analyzed through iterative coding and theme development, with trustworthiness ensured through member checking, peer debriefing, and triangulation. Results: Participants reported three dimensions of health awareness. (1) App-enabled accessibility as a catalyst for physical health awareness (i.e., physical health benefits) included improved vitality and increased motivation to maintain exercise routines. (2) App-based planning and anticipation in supporting mental well-being (i.e., mental health benefits) involved stress reduction, emotional recovery, enjoyment, and heightened self-care awareness. (3) Platform-mediated social encounters and the construction of social health (i.e., social health benefits) reflected expanded social networks, strengthened interpersonal relationships, and a greater sense of belonging fostered through shared leisure experiences. Conclusions: Smartphone-based leisure platforms play a meaningful role in enhancing users’ awareness of multidimensional health benefits. By improving accessibility, diversifying leisure options, and facilitating social interaction, these platforms support holistic well-being. The findings contribute to understanding technology-mediated leisure and offer practical implications for designing digital leisure services that promote physical, mental, and social health.
