Best Fitbit for Kids: The Ultimate Guide in 2023!

Fitbits are not for the elderly only. If you take a look at their collection you will find at least 5 models suitable for kids.

The best Fitbit for Kids should come with the reminder to move technology to encourage your teenage boy or girl to keep walking to keep fit.

Monitor your child’s heart rate whenever he or she is indulging in intensive workouts. The Fitbit should also be able to track and display stats like sleep to give your boy or girl a glimpse of how well he or she sleeps.

In addition, the best Fitbit for boys and girls should be able to count steps and the number of stairs climbed.

An optimized Fitbit will impact your child’s life positively it does not matter if they have different alternatives to the Fitbit models.

Best Fitbit for Kids: Reviews for Small Boys, Young Girls, and Teenagers

1. Fitbit Flex Wireless Activity + Sleep Wristband

Fitbit Flex Wireless Activity wristband might not be a high-end smartwatch for boys, girls, and teenagers but it’s a device your kid will need to track his or her activities.

The smartwatch feels super comfortable on the hand hence you don’t have to worry about your child getting wrist pain from the Fitbit.

Although it is comfortable it is not an option for children who want something more attractive: it is almost wholly rubber.

Though Fitbit Flex wireless activity wristband isn’t packed with Premium features like those packed on Fitbit for seniors it is still a great performer.

Boys, girls, and teens will monitor the distances they cover, the number of steps they take, their active minutes, and the calories they burn among others.

In addition, the Fitbit Flex Wrist band uses its accelerometer to track moves during sleep. This gives your child an insight into how he or she slept. As a parent, you get data to help improve your boy’s or girl’s sleep.

This activity tracker is not best for boys, girls, or teenagers who adore swimming because it is not water-resistant.

Like the original Fitbit Ace, it features a waterproof rating of IPX7. All in all, Fitbit Flex is still a fitness tracker for kids that gets a lot done.


  • Comes with a good battery life of up to 5 days.
  • Perfectly estimates your child’s fitness.
  • Feels so comfortable.
  • Has an alarm that vibrates to wake your child.


  • Do not have a GPS mode.
  • Lack of a Heart Rate monitor.
  • Lack accelerometer hence can’t count the number of stairs climbed.

2. Fitbit Ace Activity Tracker for Kids

Although Fitbit Ace is not as cool as the Ace 2, it is packed with features that are cooler than those on LeapFrog LeapBand Do and Garmin Vivofit Jr.

Fitbit Ace is able to keep track of your boy’s or girl’s sleep, count the number of steps taken, provide an estimate of calories burned, and count active minutes.

Fitbit Ace has the reminder to move technology that keeps kids active after every 60 minutes of being inactive.

The reminder feature gives your child the desire to keep fit hence developing a healthy workout routine. Your child is awarded badges whenever he or she hits a fitness target.

Your kid does not have to keep charging the Fitbit from time to time because the watch itself has a good battery life of 5 days which is fine for its price point.

No power-hungry modes like the built-in GPS found on most Fitbit for seniors. Kids get to keep all the sleep stats because unlike other fitness trackers Ace doesn’t erase sleep stats at 12 midnight.

The sleep tracking feature is important to your child because it is helpful in optimizing his or her sleep routine.

Lastly, Ace is an IPX7 watch which means it is not a water-resistant smartwatch and hence not the best Fitbit for swimming or taking a shower.

That also means it is not the best Fitbit for children and teenagers who love tracking swimming.


  • Feature the Reminder to Move technology to keep your child active.
  • Comes with badges and celebratory messages that will motivate your son or daughter.
  • Syncs with Android and iOS devices.


  • It isn’t a waterproof Fitbit.
  • Lacks the heart rate monitor.
  • Seems overwhelming to children at first.
  • The original band does not fit all wrists.

3. Fitbit Ace 2 Activity Tracker for Kids

Fitbit Ace 2 comes in as an improvement for the Fitbit Ace. The watch brings about some unique features like letting kids as young as 6 years old get the most of what it has to offer.

The Ace 2 is made tougher with additional clock faces your child will fall in love with.

What will make you love this upgrade is that it comes at a price lower that its original model hence the fitness tracker for kids to consider when you are under a budget.

Although the original Ace is not water-resistant, Fitbit Ace 2 is.

The activity tracker is rated 5 ATM which means it can resist water pressures of up to 50 meters below water. Your kid can take a shower with the Fitbit Watch or go swimming with it.

Ace 2 lets your boy or girl keep track of the step made, and calories burned, evaluate their sleep, and active minutes, and set up fitness goals.

Unfortunately, as powerful as Fitbit Ace 2 is, it still does not feature a heart rate monitor and an onboard GPS to monitor your child’s heart and routes respectively.

We hate the fact that it takes time to set kids’ accounts for Ace 2. Lastly, you may want to know how Fitbit Ace 2 and 3 compare.
