Fitbit's Ace 3 encourages kids to keep moving 15 Mar 2021 Fitbit has released the third generation of its Ace activity tracker for children, the Fitbit Ace 3. The tracker features more animated clock faces and accessories, in addition to popular features like step counts (at least 250 every hour, however, this number is customisable during school hours). Other features include daily active minutes, as well as bedtime reminders, a timer and stopwatch, and more. Children can also participate in Family Face Off challenges, and celebrate milestones with virtual badges and trophies. The Nib Parenting 2020 Survey found that 87% of New Zealand parents are concerned about the amount of time children are spending in front of a screen. Fitbit is challenging parents and children to be more active and to build healthy habits.
