The Fitbit Ace 3 Kids Tracker gets them moving more and making healthier choices.

Get your kids moving and spending less time on their phones with this fantastic fitness tracker. This watch harnesses the power and reliability of the Fitbit but gives it a more fun and engaging twist to appeal to kids aged 6+.

It has the usual activity and sleep tracking with added fun challenges and up to 8 days of battery.  With virtual badges, animated clock faces and personalised avatars, kids have the motivation to get moving with the family and find ways to best their buds in friendly competitions. Since Ace 3 is water-resistant, spills and splashes don’t stand a chance and kids can wear it in the pool when swimming.

Kids who own a smartphone will love getting notifications on their wrists—and parents will love how much easier it is to get in touch. The notification system works with select Android and iOS devices when their phone is within range.

You have the option to set up a Fitbit account for your child and enable Kid View, where they can see their stats, badges and clock faces via the Fitbit family account. In Parent View, you can easily see their activity and approve their connections.

It is also highly customisable as kids can choose from fun clock faces right on their wrist, including a rocket, a bunny, Minions and more -they even animate as they make progress toward their goals! Your child can also express their unique style by switching out their band with interchangeable accessories (sold separately).
  • Depth: 1.29 CM
  • Kids spend less time charging and more time moving with up to 8 days of battery.
  • Animated clock faces grow and develop as kids move more throughout the day.
  • All-day activity tracking shows how healthy habits add up to a healthier life.
  • Help kids form healthy sleep habits with sleep tracking, bedtime reminders and silent alarms.
  • Bring on the tumbles, adventures or lunchtime spills—Fitbit Ace 3 is water-resistant
  • Kids can challenge their family to step competitions & send each other messages or cheers in-app
  • Kids earn virtual badges and fun on-screen celebrations when they reach their goals.
  • A family account lets parents manage kid’s Ace 3 and their own watch or tracker from one easy place.
  • Height: 8.52 CM
  • Width: 2.04 CM
