Step up your game: phone app gamification aims to slash heart risks

This study looks at whether using a fun, game-like mobile app can encourage university students and employees to walk more and do simple exercises, lowering their risk for heart disease. About 105 volunteers aged 18 to 64 will be split into five groups, some using the app and some not, for 12 weeks. Researchers will measure changes in weight, blood pressure, cholesterol, and daily steps to see if the gamified approach works better than standard activity tracking.
