Help young ones stay active with the Garmin vivofit jr. Activity Tracker. This kid-oriented tracker features year-long battery life, a durable band with Digi Camo pattern, and 5 ATM water resistance. The vivofit jr. tracks steps, movement, and sleep, and it lets parents set goals and track their children through a specially designed app. The kids' app gives children virtual coins for completion of goals, chores, and 60 minutes of activity, which they can trade in for rewards you designate.
