App and wearable team up to fight the bulge

This study looks at whether using a mobile wellness app alone or with a wearable fitness tracker helps adults with overweight (BMI 25 or higher) manage their weight and get more active. About 300 people will be split into three groups: app plus tracker, app only, or standard health info. Over 12 weeks, the researchers will measure weight changes, activity levels, and mental well-being.
