This study explored how the gratifications obtained from the use of diet and fitness apps may motivate users to continue their use of these apps. The effects of seven gratifications obtained were analyzed through hierarchical regression analyses. Results showed that the five gratifications of recordability, networkability, credibility, comprehensibility, and trendiness significantly predicted user intention to continue using diet/fitness apps; the hypothesized gratifications of accuracy and entertainment were not significant predictors. These findings contribute to broadening our theoretical and practical knowledge of new digital, mobile media phenomena by identifying use motivations specific to diet/fitness apps. Based on the findings, recommendations for researchers, practitioners, and developers are provided.

This study's consideration of the relationships between existing media and health apps may guide health practitioners in their strategic approaches to improve the well-being of college students.
