The latest smartwatch for kids, the Fitbit Ace LTE, offers gamified activity tracking complete with incentive-based play in the Fitbit Arcade. From racing chickens in space to golfing around the world with a hoard of monsters, the games are as simple as they are entertaining, and most importantly, they help get children moving. But what about adults? I’m not saying access to wrist-based entertainment is the key to a fitness regimen, but I don’t see why we can’t also be motivated by addictive arcade games.
