We all know that exercise is an important part of leading a healthy lifestyle.

But getting kids up and active seems to be getting harder and harder in these technology-heavy times. When there's a screen on hand, a lot of children inevitably find it hard to pull themselves away from it and get moving.

So why not tie the two together? Fitness trackers are the perfect solution: a screen that also encourages kids to be active, it's fitness for the modern age!

A fitness or activity tracker is a device, usually worn on the wrist, that tracks your activity. This can be everything from steps walked, to heart rate, to miles run and laps swum. Used in the right way, they can be a fun way to encourage your kids to engage actively in their health, promoting awareness of what constitutes beneficial exercise, offering rewards or incentives for completing certain goals and engaging them in the best kind of competition: with themselves. Just remember to keep an eye on your child's usage to prevent unhealthy or obsessive use.

Whilst most trackers will act as your basic exercise recognition and heart rate monitors, lots of the best also come with a host of other cool features that will suit different families' needs. Some offer reminders to get moving. Some offer rewards or incentives to encourage kids to complete certain fitness activities. Some even allow you to track your child with the use of built-in GPS; useful if you want to make sure your child is safe whilst out running or playing sports with friends.

We've compiled a list of the best fitness trackers for kids with a guide to the price, age-range and their key features so you can decide which sounds best for your child.

Fitbit Ace Kids Activity Tracker.

The original kids Fitbit Ace, this one is a little pricier than its follow-up. It's lightweight, showerproof and has a 128 x 36-pixel resolution screen that changes to ten different watch face displays when tapped. Like the Ace 2, it motivates children to complete fitness goals by showing celebratory messages when they achieve them.

Rain-proof, sweat-proof and splash resistant, it has a good battery life (up to seven days) and easy cordless charging via USB.

Best For Families On A Budget

9. Letscom Fitness Tracker‍

Letscom Fitness Tracker.

This fitness tracker from Letscom is a bit of a steal. It doesn't include a heart rate monitor, but it covers almost all the other basic features you could want, with step counter, calorie monitor and mile calculator included, and a side-along app that allows you to see a more detailed activity report. It monitors sleep quality and hooks up to your phone too. Accuracy may be a little off at times (though kids are unlikely to notice), and, for this price, we'll take a few missed steps here and there.

Main Features

  • Price: £15.99
  • Age: (we recommend) 6+
  • 1-2 hour charging time
  • 5-7 days battery life
