The purpose of this paper is to examine the factors that influence the intention of patients to adopt mobile health apps. The factors selected to conduct this study are perceived usefulness, perceived ease of use, and subjective norm. The proposed research model was reviewed and validated using the PLS-SEM with a sample of 300 respondents. The results of this study showed that perceived usefulness, perceived ease of use, and subjective norm could positively affect the patient's intention to use the mobile health app. The results of this study have made it possible to fill the research gap and provide adequate statistical support to the future expansion of research in the field of mobile health app. For practical reasons, these results have also provided researchers, app developers and healthcare providers with valuable information on how to evaluate and develop effective mobile health apps from the users’ perspective.
