With the rise of health awareness in modern societies, health promotion has attracted increased attention in both academia and industry. This, along with the evolution of information and communication technologies, has stimulated the development of mobile applications for health promotion. However, users of the applications do not necessarily achieve their goals because many applications do not provide a smooth user experience. In this study, we identified the defining attributes of app usability in the context of health promotion to guide app design for improved user experience. We first explored app usability by applying Walker and Avant's concept analysis method, which involves the following steps: (a) identifying the use of the concept; (b) determining the defining attributes; (c) considering a model case; (d) considering contrary, borderline, and related cases; (e) identifying antecedents and consequences; and (f) defining empirical referents. We subsequently derived a unified definition of usability. From the healthcare perspective, the defining attributes of usability of mobile application are efficiency, user satisfaction, and learnability. Apps with these attributes can achieve their designed goals and reach maximal efficacy because users would continue using the app on a regular basis and recommend it to others.
