Best kids fitness tracker 2025: keep the little ones active

Yes, there are fitness trackers for kids. While those bundles of energy might not always need much of a nudge to ditch the big screen and go play out in the garden, there are wearables for your children that, just like the best fitness trackers for grown-ups, want to help them be active and think a little bit about their health too.

Rather than being fully fledged smartwatches like those found in the best smartwatches for kids guide, these fitness trackers typically stick to the basics and think less about monitoring heart rate or blood oxygen levels and more about rewarding being on their feet and doing that in a fun way.

There are a lot of fitness trackers from big-name and small-name brands that promise to deliver a strong activity-tracking experience, but which ones are the standout ones you should be looking at?

We’ve picked out the fitness trackers we think can help keep your kids out in the park and moving on a more regular basis.

1. Garmin Vivofit Jr 3

Garmin Vivofit Jr 3 specs
Platform	iOS and Android
Waterproof rating	5ATM
Display	MIP
Heart rate sensor	No
Notifications	No
GPS	No
Battery life	1 year

Garmin’s third-generation kids’ fitness tracker now opts for a more smartwatch-style look and keeps the year-long battery and same swim-proof rating as its grown-up trackers to make it one that can last for some time.

Once they’ve picked from a Star Wars, Disney Princess, Marvel or more standard Garmin look, children aged 4 years and above can put the accelerometer motion sensor to good use to count steps, and track sleep and distance travelled over the day.

Clocking up an hour of daily activity a day unlocks adventures and virtual rewards that do have to be accessed on a smartphone, while new fitness cards will start to introduce them to some basic exercise moves like star jumps and mountain climbers.

It looks great, offers enough features to feel motivating and fun to use and is one you don’t ever have to remember carrying a charging cable around for.

Platform	iOS and Android
Waterproof rating	5ATM
Display	OLED
Heart rate sensor	No
Notifications	Yes

Battery life	Up to 8 days

A fitness tracker made by Fitbit feels like the perfect match and with the Ace 3 you’re getting a fun-looking band that stays true to Fitbit’s core and aims to make staying active more fun.

It starts with the looks on offer, which does include a special edition Minions version, which also throws in a themed watch face to give the swim-proof Fitbit tracker more appeal.

Features-wise, it tracks steps and active minutes and also offers more basic sleep-tracking support than Fitbit’s adult trackers, with bedtime reminders to tell them when to get to sleep. There are virtual badges to unlock, the ability for smartphone-owning kids to view notifications and parents can keep an eye on progress and any incoming invites to connect with your children.

It’s the best fit for children aged 6 years or over and offers a good start to get them thinking about staying fit and even the importance of getting to bed at a good time.

Xplora XMove specs
Platform	iOS and Android
Waterproof rating	IP68
Display	TFT
Heart rate sensor	Yes
Notifications	Yes
GPS	No
Battery life	Up to 10 days

Xplora has mainly flexed its muscles making feature-packed smartwatches for kids but it’s also stripped things back for parents that just want their kids to focus on getting up and out.

With the XMove it’s offering a tracker with a smartwatch-style design that comes in four colours and has an IP68 waterproof rating, which means while not fully swim-friendly it can survive being splashed in the rain.

There are sensors on board to track movement, sleep and send a nudge when they’ve been sitting for too long. There’s a heart rate monitor and workout modes for running, cycling and walking to give it appeal for older kids and also uses Xplora’s GoPlay platform to earn coins and unlock physical rewards.

A solid 10-day battery life means a good amount of time in between charges to collect those coins, work towards those prizes and most importantly, get those step counts in.

4. Tikkers

Tikkers specs
Platform	iOS and Android
Waterproof rating	N/A
Display	LCD
Heart rate sensor	No
Notifications	Yes
GPS	No
Battery life	Up to 7 days

Among the many lesser-known fitness tracker makers, UK-based Tikkers makes one with a familiar-looking slim design that focuses on counting steps, monitoring sleep and offering some other smarts, like controlling your smartphone camera from your wrist.

Designed for users aged 6 and above, it does offer older users the ability to view phone notifications, receive alerts for incoming calls, log water intake throughout the day and set goals for just how active they want to be each day.

You can swap the bands for additional designs all offering a water, scratch and dust-resistant design that gives it a good level of durability and the ability to handle some rough and tumble. The battery is typically 3 days, so not the best you’ll find, but if you can handle charging every few days, then it’s a tracker that offers good bang for your buck.

5. Biggerfive Vigor 2

Biggerfive Vigor 2 specs
Platform	iOS and Android
Waterproof rating	IP68
Display	LCD
Heart rate sensor	Yes
Notifications	No
GPS	No
Battery life	Up to 7 days

Another lesser-known tracker, Biggerfive’s Vigor 2 kids fitness tracker is clearly inspired by Fitbit’s Ace tracker offering an IP68 waterproof-rated design that comes in four different colours and promises a week’s worth of battery life.

It has sensors on board to let children aged 5-12 monitor daily steps, sleep, and heart rate, while there are also activity modes for the likes of running, cycling and sports like basketball and tennis to be logged in the Biggerfive companion app.

You can set a silent alarm clock to gently nudge them awake in the morning, take a pick of multiple watch faces and it’ll remind wearers to move when they’ve been inactive for long periods.

While it doesn’t quite match the feature set of Fitbit or Garmin trackers it does deliver those activity and sleep tracking staples for both Android phone and iPhone-owning parents to set up and hand over to their kids.

How to choose the best kids’ fitness tracker

When choosing the best kids’ fitness tracker, the first thing you’ll want to look for is an age-appropriate design and durability. The fitness tracker should be lightweight, comfortable, and easy for children to use. It should have a durable build to withstand the wear and tear of active play.

Additional features like water resistance can protect the device from accidental splashes.

If your child is young, the tracker should have a colourful and appealing design to engage them and make them excited about using it. If you have an older child, they’ll probably want a more grown-up design.

Essential features for a kids’ fitness tracker include step counting, sleep tracking, and activity monitoring to encourage healthy habits. Additional educational or motivational features, such as games, rewards, or challenges, can make fitness tracking more fun and engaging for kids.

Ensure the device has a user-friendly interface that kids can navigate easily.

Parental controls and a companion app for parents to monitor their child’s activity and set goals can be beneficial.

Finally, battery life is also crucial; a longer battery life means less frequent charging, making it more convenient for both kids and parents.
