Fitness Trackers for Kids: Buying Guide

Here are some factors to consider when choosing a fitness tracker for your child.

Waterproof or Water Resistant Properties

The best fitness trackers for kids should be waterproof. If your child loves water-based activities such as swimming, surfing and diving, then be sure to get a fitness tracker that is waterproof. However, even if your kids don’t swim, they are likely to engage in activities that will cause spills or splashes. Make sure that your tracker is able to withstand them.

Note that some manufacturers market their fitness trackers as waterproof when they are actually water resistant. Water-resistant trackers can withstand a few splashes or spills but would get damaged if immersed in water. Others are waterproof-rated, for submersion into certain depths of water.


Since your child will be wearing their fitness tracker for extended periods of time, it is important that it comfortable on them. Most kids’ fitness trackers are made of silicone, which is flexible and feels soft on the skin.

A one-piece design is more appropriate for younger children while a watch-style design is more appropriate for older kids.

Also, consider the screen size. The screen should be big enough for your child to be able to read it, but not to too big that it feels bulky.

Battery Life

While some fitness trackers for kids require charging after a few hours of continuous use, others have a battery life of up to a year. Choose a fitness tracker whose battery life suits your child’s lifestyle, frequency of use and length of time per use. When charging, ensure to adhere to the manufacturer’s instructions, as failure to do so may negatively impact the battery’s performance.

App Compatibility for Parents

Most trackers come with an app that you can sync in order to get real-time data about your child’s activity level. Some apps allow you to set goals and add challenges and rewards for family members. This can be motivating to the kids. It encourages engagement for all family members and makes fitness fun.

Sleep Monitor Feature

While some fitness watches for kids have a sleep tracker, others do not. Ensuring that your child gets enough sleep is paramount to their overall health. A sleep monitor will give you an overview of how much sleep and the quality of sleep your child is getting. However, if you are concerned about your child wearing a gadget to bed, then this might not be a critical feature for you.


Some fitness trackers have limited customization options, while others allow you to customize nearly every aspect. For instance, some allow you to enter your child’s name and choose a display color and font as well as background graphics. They also allow you to choose the specific type of data you want to have displayed, e.g. time, pace, steps and calories.

Other Features

Depending on your child’s interests, you can choose a fitness tracker with additional features. For instance, some have games that can be unlocked as rewards for reaching certain targets. Others double up as a watch, while others are programmed to offer educational value.

Other features you might consider include Bluetooth connectivity, music sync, GPS, etc. Keep in mind that the more the features you opt for, the more expensive the fitness tracker is likely to be.


A fitness tracker might be the motivation your child needs to get off the couch and go play. However, be mindful of them becoming too obsessive about the calculations, as this will wring the fun out of physical activity. Also, if your child does not want to wear their fitness track for one reason or another, it is best not to force them.
