With motivating virtual competitions and a long battery life, this activity tracker is designed for kids aged 6 and up to make fitness fun. Through a family account, parents can approve their child's contacts. Kids can view their statistics, badges, and watch faces in a protected view. The Ace 3 comes with various accessory bands in great colors. For children who have a smartphone, receiving call notifications on their wrist is a fantastic feature – and it also makes it easier for parents to reach them.
