Smartphones have been blamed for everything from taking drivers’ attention from driving to keeping people on the sofa scrolling (滚屏) videos.But the smartphone that seems to be everywhere could just easily increase physical activities if it pushes its owner’s buttons in the right way.

　　New research shows that making social connections through activity-tracking apps gets people to move more.And a separate study on this summer’s “Pokemon Go” phenomenon shows that the smartphone game got players to take more steps than usual.Together,the studies show the potential for smartphones to push a range of people to be more active.

　　People who linked with friends on the activity-tracking app increased their steps by 400 a day on average,compared with people who made no social connections,according to Tim Althoff and two other computer scientists at Stanford University.The effect of social connections declined,but remained significant for five months before the numbers fell back even with users who made no connections.

　　Such insights show the promise of smartphones and games to help with one of the most stubborn public health problems—that even people who want to be active have trouble staying active.

　　An NBA videogame,for example,gives players extra power in the game if they reach a step goal in real life.The app “Zombies,Run!” uses audio stories to push people to run more or run faster.

　　Still,there is room for growth.Only about 4% of all health apps use “gamification”,according to a study published in October in BMJ Open.“Gamification is actually quite closely linked with behavior change techniques,” says Dr.Elizabeth Ann Edwards,the study’s lead author and a doctor and researcher at Queen Mary University of London.
