Fitness Tracker FAQs

  1. What is a fitness tracker for kids?  

A fitness tracker is a wearable electronic device that helps people keep track of their activity levels. It can help them keep track of the steps they walk every day, miles that they run, provide data on sleep quality, and some of their vitals. 

The best fitness trackers for kids will count their steps or the amount of time they are active. Parents can set activity goals, and some trackers will unlock games when they accomplish those goals. Parents can set reminders to do chores on trackers as well. For teens, a fitness tracker is closer to what an adult might wear, but parents can set goals and reminders on them as well. 

  1. How does a kids’ fitness tracker work? 

Kids can wear a fitness tracker around the wrist to measure when they are in motion, whether it is walking, jogging, or not moving at all. Most of them come with three-axis accelerometers, which is a device that measures movement.

Some trackers also have gyroscopes that can measure rotation and orientation as well. The data these devices collect then converts into steps or activity, and then into calories or sleep quality, whichever data your fitness tracker offers and that you want to check.

Children’s trackers have most of the same sensors and devices inside of them that adult trackers do. But they may supply different types of information. Instead of monitoring blood pressure, a kid’s tracker often monitors steps and activity levels throughout the day. They can also track goals that parents have set on the device. 

Usually, the data is a little different in each fitness tracker depending on the child’s age. A tracker for a four-year-old may count activities and teach him or her how to eat healthy by making a game of it. For a teenager, they may be more concerned with getting in shape for their sport and can use their tracker to do so. 

  1. Where can you buy a kids’ fitness tracker? 

If you cannot find a children’s fitness tracker in retail stores that sell adult versions, such as Kohl’s, Best Buy, or Academy Sports and Outdoors, then go online. They are available on websites like Amazon, Etsy, or the sites of the retail stores previously mentioned.

Kids Fitness Tracker Buyer’s Guide: How to Choose the Best Fitness Tracker for Children

If you think your child spends too much time playing video games and not playing outside, then a fitness tracker can help you find out how much they walk, run, and play each day. However, since fitness trackers look delicate, and some of them are not cheap, you’ll want to consider trackers that are durable, water-resistant, and find out how it’s powered.

When shopping for a child’s fitness tracker, consider its durability. Kids can get rough when they play and don’t always consider what they’re wearing when playing or exploring. As a result, the fitness tracker may receive bumps, scratches, and accidentally go underwater when they’re cleaning up or splashing in puddles.

Look for a tracker with a rubber or plastic band that won’t get wet, won’t mildew, and on which dirt or water quickly wipes off. Pick one with a scratch-resistant crystal too, so it’s still legible after your kid has been playing while wearing it. 

Finally, consider the power source of the device. Most adult trackers need recharging frequently, but kids are not always responsible with their devices, and the battery may run out of power. Look for one with a long-lasting battery that is easy to recharge by plugging it into a USB port on a computer.
