It keeps track of every move your child makes to promote a healthier and active lifestyle. It provides vital information that includes sleeping patterns, number of steps, and active minutes.

Similar to the adult version, the Fitbit Ace 2 has an interactive app where kids can find motivational challenges. This also gives adults complete control over the majority of the content.

The Fitbit Ace 2 also works great for swimming since it’s water-resistant up to 50m. Your child can wear it in the shower or take a dip in the pool. So have no fear of accidental splashes and spills!

To make things even more interesting for the kids, the Fitbit Ace 2 has fun badges and avatars as rewards to encourage them along their fitness journey and help them adopt a more healthy lifestyle.

A Guide to Buying the Best Fitness Trackers for Kids

How to choose the best fitness tracker for your kid

Every year brands come up with new models of fitness trackers. While this constant innovation is great, it makes things confusing when you’re choosing the right device for your child. 

To make things easier for you, we have compiled a list of the most crucial factors you should consider before settling on a particular product.

Display

It’s best to buy an advanced tracker that can clearly display recorded data, including numbers, words, and symbols. You can opt for a simple LED display, which when synced to a smartphone or computer, gives you a detailed analysis of your child’s activity levels.

In addition, if the device is compatible with an app, make sure you download and check the app before buying the device to see if it has the features you want and is worth your money.

Style

Since kids are involved, you have to look for kid-friendly designs when buying fitness trackers. While most traditional fitness trackers are designed to be worn on the wrist, you can also find pendants or clip-ons. The idea here is to choose a model that would be most functional for your child.

You should also consider the color, shape, and material on the fitness tracker. While animations and cartoons would be more suitable for young children, you can opt for sleek and solid color bands for teenagers.

Accuracy

We hate to tell you this, but fitness trackers aren’t completely accurate.

Yes, they have sensors and algorithms that allow them to keep track of footsteps, sleep patterns, and heart rate, along with other aspects of your child’s lifestyle — but they’re not foolproof. 

If you want something that’s 100% accurate, we would recommend you to look for other devices. But if a little imprecision isn’t a dealbreaker for you, fitness trackers are your best bet.

Battery Life

Battery life is very important when it comes to buying fitness trackers, at least for us. After all, what’s the point of having a fitness tracker if it has to be left on the table for the majority of the day for charging?

Luckily, you’ll find plenty of devices that offer a longer battery life, ranging from a full day up to a year. Trackers which have more sensors and a touchscreen will need to be charged more frequently as opposed to one with a simple design.

Make sure you check whether the battery is rechargeable or non-rechargeable. There’re a few models that run on coin cell batteries that are commonly used in traditional cameras and calculators.

Water Resistance

If your child is a budding swimmer or loves to spend time by the pool, it would be best to look for water-resistant or waterproof models. While some models are merely splashproof, other have a greater resistance and can survive a dip in the pool or a hardy shower.

Compatibility

We would highly recommend opting for fitness trackers that are compatible with your personal smartphone and computer.

Some models can only be synced with Apple’s iOS, while others might only support Android. If you use Windows, you need to be extra careful since most fitness tracker models aren’t compatible with it.

At what age can kids start wearing a fitness tracker?

If you thought that fitness wearables are only for adults, think again.

Parents have started to buy fitness trackers for children as young as four years old to make them more aware of the benefits of healthy living. Moreover, physical inactivity is a common problem among children, with the World Health Organization (WHO) calling it one of the leading risk factors of death.

Whether or not you want your child to wear fitness wearables, there’s really no harm in encouraging them to increase their activity levels to keep them fit.

How do fitness trackers work? Are they safe for children?

Fitness trackers come fitted with sensors that can monitor your movements. These devices are connected and synced with mobile phones, tablets and computers to store data about your day-to-day routine.

Furthermore, different fitness trackers can monitor different types of activities, including the number of hours slept, heart rate, skin temperature, the number of steps walked, perspirations levels, and so on.

They use the following sensors to give you a (nearly) accurate reading:

  1. Heart rate monitor to track pulse throughout the day
  2. GPS to track your child’s location
  3. Gyroscope to determine the kind of activity your child does.
  4. Barometer to measure altitudes, which is useful to calculate the number of flights the child has climbed.

As you may have realized, fitness trackers don’t really have anything that could be potentially harmful to your child. On the contrary, they do show immense potential when it comes to ensuring your child starts becoming more health-conscious — even if it’s temporary.

Are there any cons to giving my kid a fitness tracker?

Yes, as mentioned above, it could promote an unhealthy obsession with calorie counting and being of a body image that conforms to society’s views of how an ideal body should look like. You should stress to your kids not to be too concerned with these things, and that the fitness tracker is only to track their physical activity throughout the day, to ensure they’re not staying sedentary for too long in front of the phones or tablets.


Final thoughts

There’s no doubt that fitness trackers can be a great purchase for kids. Not only are you able to keep track of your child’s movements, your kid also becomes more conscious about what they eat, how they sleep, and most importantly, how active a life they live.

The Fitbit Ace 2 is definitely the winner in our research with its combination of durability and functionality — all of which are available without you having to break the bank. You can also consider our other top picks, the BIGGERFIVE Fitness Tracker Watch and Garmin Vivofit Jr. 2, that offer great features and style.

Irrespective of the choice you make, you can rest easy knowing getting any of these best fitness trackers for kids could be helpful to encourage your child to live a healthier life.

Now you can find out how much physical activity your kids get up to with these best outdoor toys for 10-year-olds, and these best nerf guns and laser tag guns for the whole family!
