The Garmin Vivofit Jr 2 activity tracker has kid-friendly designs and is on sale for $20 off

If you have kids that are super active and play a lot of sports or swim or anything like that, you should get them an activity tracker this year. It's a great way for them to see the impact all that activity is having on their health. The Garmin Vivofit Jr. 2 activity tracker is down to $49.99 on Amazon, and it comes in a variety of different designs at that price. Get Marvel's Spider-Man, a couple different Star Wars designs, Disney's Frozen II, and more. These trackers normally sell for around $70 or more, and the $50 drop is a new low for most of them.

The tracker will last for more than a year. You don't recharge it. You just replace it, and that's very easy to do. The band features a customizable color screen, and it is swim friendly.

Plus, parents can use the parent-controlled app to access chore management, reward tools, and more. You can work together with your kids so you both stay involved. Kids will get reminders to help them stay on top of tasks that need done like homework or chores, and they can use the timers for practice and other things. You can even set a timer for things like brushing teeth to help develop good habits.
