Getting an activity tracker for your kid can not only help you better understand their current activity level, but it can also help you teach your children valuable skills, like realistic goal setting, a commitment to a healthy lifestyle, and also how to take care of an expensive device.

The super kid-friendly and simpler Vivofit Jr 2 is a tracker that excels at helping parents plan and schedule their kid's time, making it great for younger children that require more structure. The Fitbit Ace takes a little more of a hands-off approach and is most likely better suited for preteens or teenaged children.

The important specs

Fitbit Ace and Vivofit Jr 2 both take different approaches to the wearable tracker. The Fitbit Ace acts like all the company's other trackers, having a tap-on display, tracking all the metrics (steps, calories, sleep, and more) you'd expect, and has a 5-day battery life that means you'll need to make sure your kid charges the Ace every so often.

The Vivofit Jr 2 takes a simpler approach to a children's tracker, by making it a device that kids can mostly put on and leave it alone. It has a replaceable battery that should last about a year, and the major metric (almost only) it tracks is steps per day.

The biggest difference between the Fitbit Ace and Vivofit Jr 2 is how they handle the app experience.

Fitbit's app infrastructure is pretty great and if you have any other Fitbit technology in your home, the Fitbit Ace will play nicely with it. It's also meant to be paired with a phone, so your child will get more out of it if they have a phone themselves. Fitbit splits its app into two different views — a kids view and a parent view — that lets your child see various metrics but allows the parents to set goals and view all the data the Ace collects.

The Vivofit Jr 2 is more for young children while the Fitbit Ace is better suited for older children.

The Vivofit Jr 2 doesn't give kids any control over a app, but rather leaves it all up to the parents. It's always-on display has the time and steps per day prominently featured, but your child can't see any metrics byond that. When it comes to setting goals or assigning tasks (likes chores or other reminders) the Vivofit Jr 2 does that all trough the parent app. The goals can even provide rewards to give your kid something to work towards.

The Vivofit Jr 2 is much less a serious activity tracker, and much more a device that can help you schedule your child's time and help you open up a discussion about the importance of meeting goals and general time managment. I think that makes the Vivofit Jr 2 a much more practical device for children who don't have phones already and are on the younger side.

On the other hand, the Fitbit Ace takes the training wheels off, so the device requires a little more thought than the Vivofit Jr 2. I see the Fitbit Ace being perfect for preteens and teenagers alike and a great tool for teaching your children how important activity truly is for a healthy lifestyle. It offers your child more independence and works much better if your child has a phone to pair with it, so they can track their data for themselves.

When it comes to your child, you know them better than anyone, meaning you can make the call on which tracker to get.
