Twenty five percent of adults currently use either a fitness tracker or smartphone app to track their health, weight, or exercise, according to a survey conducted by TechnologyAdvice. More than 900 U.S. adults answered the survey, which asked questions about general fitness tracking habits. The research also revealed that more people would use wearables if there were some incentives. Forty four percent of respondents would use wearables if it meant better advice from their physician, and 57.1 percent would use a wearable if it led to lower health insurance premiums. Other highlights from the survey can be found in the infographic below.
