About this product

Get kids moving and make fitness fun with Fitbit Ace 3. With activity and sleep tracking, fun challenges and up to 8 days of battery, Ace 3 motivates kids, friends and family to build healthy habits together.

Kids spend less time charging and more time moving with up to 7 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 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.
