9 Best Fitness Trackers for Kids in 2021

Kids are always so vibrant and full of energy. It’s adulthood that makes us the dreary and exhausted individuals that we’ve become over the years. When we were kids, it was like our feet didn’t stay on the ground, and we were always flying off to do something or the other with our peers. Be it skating, cycling, running, playing hide and seek, building a treehouse, or any other activity, kids have too much energy to invest in it without getting tired.

Sadly, today’s kids are also becoming lethargic and exhausted, and it’s mainly because of the unhealthy lifestyle that we’ve subjected them to. Health problems that were only native to adults, like diabetes, high cholesterol and obesity, have also become common in kids, which is why parents have to become extra careful to ensure that their children are getting enough activity, rather than sitting on their beds all day, playing video games or watching Netflix.

The best way to go about this is to get your kids out and about, and indulge them in physical activity. Not only that, but you can pair it up with a fitness tracker that’s made specially for kids, so that they can track their daily progress and also work harder towards staying fit and healthy. If you’re thinking of just handing down your fitness tracker, let me stop you right there.

The Ace 3 has a couple of useful features, such as step counter, sleep tracker, do not disturb, timer, and many others. It also provides them with virtual badges and celebrations when they fulfill certain challenges.

Fitbit Charge 3 – Best Fitness Tracker for Older Kids

One Of The Best Fitness Trackers Out There

Fitbit is known to manufacture the best and top-of-the-line fitness trackers and devices, and when it comes to kid-friendly fitness trackers, the Fitbit Charge 3 leads the pack. Although the Fitbit Charge 4 has already been released, this fitness tracker continues to be one of the best models out there to date. It offers a wide range of excellent benefits that help kids monitor their health efficiently.

The design of the Charge 3 is quite similar to the Charge 2, but there have been minor improvements and changes. For starters, this fitness tracker has become much thinner and it’s also lightweight, since it’s made from aluminum. It comes with an adjustable silicone band that can be easily placed on the wrist and adjusted for a comfortable fit.

The Charge 3 has a full touchscreen monochrome display that has a smooth response and easy navigation. This screen is larger than the previous models and although most people might argue that it’s only monochrome, it has much better resolution than its competitors.

Apart from this, there is a small and easy to press button that you can use to wake up the screen whenever you need to. The button also vibrates gently to know you it’s being pressed. The Charge 3 comes with a plastic strap when it’s bought, and to be honest, the strap looks lower in quality than the silicone bands you’d normally find in fitness trackers.

The Charge 3 also enables your kids to remove the strap with the help of the metal button placed beneath the fitness tracker. This allows them to easily replace its strap. Another great feature of this fitness tracker is that it’s also waterproof. Plus, you can use the Charge 3 to track your child’s swimming progress as well, which is a highly useful feature.

Due to its simplistic design and functionality, the Charge 3 is more suited towards pre-teens, and it can help them track and record a great deal of activities accurately. It also includes timers, weather and the ability to connect with your smartphone. Once you do this, the fitness tracker uses your phone’s location for showing various information, and it also displays the phone’s notifications to you.

In terms of its price point, the Fitbit Charge 3 is pricier than most of the high-end and normal fitness tracker for kids, but its wonderful features make it worth buying.

Amazfit Bip Smartwatch – Best Fitness Tracker for Teenagers

A Cool And Trendy Fitness Tracker For Kids

My next pick is specially for the cool teens, who might think that kids’ fitness trackers are childish and lame. The Amazfit Bip Smartwatch is one of the best and most popular fitness trackers out there, and it has amassed popularity for its great battery life and performance.

The Bip has a modern design that looks similar to the Apple Watch. It has a wider and adjustable silicone strap with a square and rounded screen. It has a color touchscreen display with Corning Gorilla 3 glass that can be easily navigated to cycle between different modes. The display is bright enough to be visible, even in daylight.

Leapfrog LeapBand Activity Tracker – Best Fitness Tracker for Little Kids

Set Your Little Ones On The Right Path

If you want your kids to get started on fitness from a young age, you should get them the Leapfrog LeapBand Activity Tracker, which encompasses a fitness tracker with a virtual pet device. It keeps your kids active and rewards them for performing and fulfilling different challenges.

At first glance, the LeapBand looks like a compact gaming device for kids. It has a simple and colorful design, along with a bright interface. It contains four buttons, a speaker, and a bright color display. The fitness tracker is quite lightweight and feels comfortable on your kid’s hand, so you don’t have to worry about feeling too heavy. Since it doesn’t have a touchscreen display, your child may be confused while using it.

The LeapBand has pretty basic controls and it isn’t difficult to understand for your little one. Plus, the speaker is loud enough to provide easily audible instructions and words of encouragement. To set up the fitness tracker, you’ll have to pair it up with your computer with a USB cable. Then, you’ll have to download the Leapfrog Connect application and use it to set parental controls or add more challenges to the LeapBand.

In the beginning, there are 10 pre-installed games that children can play and as they complete different levels, they have more than 40 unlockable games that they can access.

VTech KidiZoom Smartwatch DX2 – Best Fitness Tracker with Camera for Kids

A Multipurpose Fitness Tracker For Kids

Moving on, let’s have a look at the VTech KidiZoom Smartwatch DX2, which is one of the best sellers when it comes to buying a smartwatch for children. The best thing about it is that while it’s more of a smartwatch, it’ll give kids a reason to wear it on them all the time.

The DX2 is aimed at young kids aged 4 to 12, but it may be a tad bulky for the little ones. This fitness tracker has a rubber strap that comes in various bright and vibrant colors. Then you have the digital interface, which has a rounded rectangular shape and a touchscreen color display that shows everything clearly. The touch is smooth and easy to operate for kids, and they can easily locate the pedometer to see how many steps they’ve completed.

Above the screen of the DX2, there’s also a camera installed, which allows your kids to take selfies, even while they’re taking a walk or doing any other activity. Then, there’s another camera installed to the side, and the home button is also located next to it. This button can be used to wake up the screen whenever it goes off or to bring the smartwatch to the home screen instantly.

The DX2 also allows your kid to customize the clock face and choose between various options. Moreover, they can also add fun sound effects to play every time they wake up the screen or press the home button.

The cameras aren’t of a very high quality, but they’re pretty decent. Both the front and side cameras are of 0.3 megapixels and can be activated by the button positioned on the left side of the fitness tracker. Plus, there are quite a few photo editing tools available on the watch, which your children can use to add frames, effects, or filters to their photos and make them better.

While the DX2 isn’t a fitness tracker, per se, but it does have a pedometer that keeps recording your kid’s steps as they move around the house or in school. This is suitable for parents who want to start their kids off on a journey to fitness, but don’t want to push them too much. Considering its quality and features, I’d say the DX2 is a tad costlier than it should be.

Garmin Vivofit Jr. – Best Designed Fitness Tracker for Kids

The Best Fitness Tracker For Tweens

Last but not least, let me introduce to you the Garmin Vivofit Jr., which is the first edition of the Vivofit series by Garmin. Although there are newer models that we’ve already discussed in this list, nothing beats the Vivofit Jr. when it comes to design and style. I’m sure your kids will agree with me too.

It’s safe to say that the Vivofit Jr. isn’t just a fitness tracker – it’s a lot more. It features a stretchy silicone wristband that fits wrist sizes between 145mm and 170mm easily. There’s no clasp to take care of, so kids can easily put this on their wrist. The case of the fitness tracker is made from a high-quality polymer, and the strap itself is high-quality silicone, so your kid’s skin doesn’t get affected by wearing this for a long time.

The wristband comes in three different designs: Broken Lava, Real Flower, and Digi Camo. You can show these options to your kid and let them decide which one they like the most. Plus, you also have the option of changing the band with a larger one, once your child starts growing. This way, you won’t have to buy them a new fitness tracker for a long time. Plus, the fitness tracker also has 5 ATM water resistance, which makes it suitable for water activities.

The Vivofit Jr. is powered by a replaceable CR1632 coin cell, which can easily last up to a year before needing replacement. This means that your child won’t have to charge their fitness tracker or worry about running out of power for a long time. However, you’d have to check when the battery needs to be replaced.

The Vivofit Jr. has a small monochrome non-touchscreen display and a button right underneath it, which you can use to cycle between different settings and features. You can also pair the Vivofit Jr. with your smartphone and use it to view your child’s stats, achievements, and all other information. Apart from tracking your child’s steps, this fitness tracker also monitors their sleep and determines whether they’re sleeping peacefully or not.

Also, the app allows parents to set different tasks and challenges for children. After completing each one, parents can reward them with virtual coins that they can utilize for receiving something special or a treat of sorts.

You might find the Garmin Vivofit Jr. to be a tad costlier than the other fitness trackers out there and for a lower price, you might even be able to get the Garmin Vivofit Jr. 2 or 3.

How to Choose the Best Fitness Tracker for Kids?

Now that you’ve gone through my list of the best fitness trackers for kids in 2021, you might be thinking how I actually came up with the list. Well, there are certain factors that come into play when you’re choosing the best kids’ fitness trackers, and here they are.

Sleep Monitoring

Knowing whether your kids are sleeping peacefully or not is very important, and most fitness trackers offer this feature. This feature will help you determine for how many hours your child sleeps on average, and whether they wake up at night or not.

Waterproofing

Children tend to make a lot of spillages and splashes, even if by accident. Therefore, you wouldn’t want to buy a fitness tracker that goes out as soon as they spill orange juice on it. So, look for fitness trackers that have at least an IP67 waterproof rating, if not 5 ATM.

Comfort

If you expect your child to wear the fitness tracker all the time, even when they’re sleeping, then you should ensure that it feels comfortable on their wrist. For this, you’ll have to determine that the fitness tracker is lightweight, and it should have an adjustable strap, preferably made from silicone. You can also choose one-piece wristbands that are easier to slip on.

Battery Life

If you’ve gone through the list above, you’d know that most fitness trackers have a rechargeable lithium ion battery that lasts anywhere between 5 and 15 days. On the other hand, there are also battery cells or coin cells, which last for up to a year and don’t need recharging. If you think your child can be held responsible for charging the fitness tracker regularly, then you can go for the models that have a lithium ion battery.

Smartphone App

Most fitness trackers come with smartphone apps, which not only record the child’s activity data, but also allow parents to track their child, monitor their fitness, set parental controls, and much more. It’s always wise to choose such a fitness tracker, because it allows you to supervise your child properly.

Conclusion

This brings us to the end of our exhaustive piece on the 9 best fitness trackers for kids in 2021. I’m sure you’ve read through all of it, and I commend you for that! However, some of you may still be confused between a few of the options that I’ve handpicked, and rightly so. The best way to solve this problem is to apply the product buying guide that I’ve listed in the previous section.

By doing so, you’ll be able to weigh each fitness tracker against another, and slowly eliminate the options one by one, until you arrive at a solid option. It may also be possible that while you’re searching for the best fitness trackers for kids, you may come across an option that doesn’t belong to this list. Even so, you can use my guide to determine if that’s the right one for you or not.

I know that you want me to pick a clear winner from the lot, so you can also get peace of mind. Well, for me, the fitness tracker that takes the cake is the Fitbit Ace 3, which has all of the things that you would need from a fitness tracker: good battery life, sleep monitoring feature, IP67 waterproof rating, comfortable silicone strap, and it also comes with the Fitbit smartphone app! Plus, the Fitbit Ace 3 also has a good price point and it suitable for children of all ages.

Moreover, I’d choose Garmin Vivofit Jr. 2 as the runner-up, because it also fares well according to the criteria that I’ve mentioned above. Now, you can either follow my suggestion, or take your pick from my list. Either way, you’ll end up with a great fitness tracker to put your kid on the path to fitness!
