The utility of wearable fitness trackers and implications for increased engagement: An exploratory, mixed methods observational study.

The reported use and helpfulness ratings of various features of wearables appeared to vary based on the wearer's gender, race/ethnicity, exercise goal, exercise proficiency, preferred type of exercise, and psychosocial metrics but the results are inconclusive. Future research should evaluate whether engagement with certain features is strongly associated with improved outcomes and whether the use of these features is significantly associated with wearer characteristics.
