Mobile fitness apps offer a novel and powerful channel to deliver behavioral interventions at a massive scale. As thousands of fitness tracking solutions emerge, the lack of systematic research quantifying their effectiveness on exercise outcomes becomes more prominent. Drawing on the self-regulation and self-presentation literature, this paper elucidates the effects of mobile fitness app on health outcomes. Specifically, this study examines two common motivational designs of mobile fitness apps, namely private tracking and social sharing, on app usage, which in turn influence health outcomes in the long-run. The results of our longitudinal field experiment reveal strong evidence that mobile fitness apps help improve health. Furthermore, compared with private tracking, social sharing leads to lower body fatness and higher physical fitness, however the effects of social sharing diminish over time. The theoretical and practical implications of the findings are discussed.
