Thousands of smartphone apps geared toward monitoring health behaviors are released regularly. Even as developers flood the market with mHealth apps, consumers seem overwhelmed with choices and report lack of sustained use, which raises questions about their efficacy. An online survey (N = 513) found that perceived interactivity not only has a direct effect but also exerts an indirect effect via greater autonomous regulation on users’ attitudes and behavioral intentions toward mHealth apps. Frequency of tracking and updating personal data showed significant effects on behavioral intentions. Theoretical and practical suggestions for the design and evaluation of mHealth apps are discussed.
