Fitbit Ace Review

Fitbit Ace Review

Fitbit is probably the most known brand when it comes to fitness trackers. Recently the released the Fitbit Ace, which is an activity tracker specially designed for kids. It’s a way for mothers to monitor how active their children really are and provide motivational games to keep them interested. But unfortunately the modern world has much more distractions to keep the kids inside. So the goal of this review is to find out if the Fitbit Ace can actually be of help and if it’s worth the money.

The new Fitbit Ace looks exactly like their Alta activity tracker. Only difference is the size of the band, which is much smaller on the Ace! It’s an adjustable band that’s designed for wrists within the circumference of 127-161 mm / 5.0-6.34″. Which is generally for kids between the age of 8 to 13.

For those who haven’t seen the Fitbit Alta before, the Ace activity tracker is incredibly lightweight (15 g / 0.03 lbs) and discreet. This is perfect for children as it’s the perfect size. So it’s not too heavy for them, nor does bother when it’s on their wrist. The tracker is also made out of stainless steel, which makes it incredibly durable as well. Plus, it even has an IPX7 waterproof rating. Which means that it can be dropped into 1 meter / 3 ft of water and it will work as normal.

Fitbit Ace Design

Like I mentioned before, the only difference between them is the band. It’s made out of flexible plastic. Basically rubber but much stronger. You can also switch out this band for the one designed for the Fitbit Alta. So when your kid gets older than 12 years old, then you can just buy a bigger band instead of a new activity tracker.

The Fitbit Ace comes in two colors: purple and royal blue. I wish they made some more graphic bands as well for the younger kids. I’m sure they would like to have something with cartoon characters. Or at least some extra colors as well. Such as yellow and red at least.

Perhaps they put all their focus into the screen, which is pretty impressive for fitness trackers in this price range. It’s an OLED display that has a 128 × 36 pixel resolution. And it’s a touchscreen! You can move through different displays by just tapping on the screen. The OLED screen is also incredibly bright and sharp. Even in the daylight.


Despite the impressive OLED screen, it’s still pretty small. Which means that there’s only so much that can be displayed on it. It also depends on the type of clock design you choose. There are in total 10 different options, all of which display different data. It can display the current time, the date, goal progress and steps taken. But that’s not all. The screen also shows fireworks when you reach the goals that have been set.

Besides the screen, the Fitbit Ace also has a small vibration motor built inside it to deliver notifications. It lets your kids know when it’s time to get active or when they have reached their daily goals. Or, as a parent, you can also use it to buzz them.

Just like the Alta, the Ace does not come with a heart rate monitor or a GPS sensor. It uses an accelerometer to keep track of the activity. It can also be used to track sleeping patterns if it’s worn to the bed as well. All of the data is sent straight to the app, which I’ll talk about more below.

How accurate is the Fitbit Ace? Well it’s just as accurate as any other of their activity trackers. Obviously there can be some anomalies here and there but generally it’s pretty accurate. I also like that they have added the sleep tracking feature as well. It shows periods of when you were experiencing restlessness and when you were deep a sleep.

These activity trackers that are designed for kids, are mostly known for their excellent battery life. The same can also be said about the Fitbit Ace. It lasts around 5 days, which is really good. It takes up to 3 hours to fully charge it again and it comes with a clip on USB charging cable.


The Fitbit Ace requires installing an app onto your iOS or Android device. Through that app, you need to first set up an account and then create a Family account. This family account is for the child. Through that app, you can choose between the Parent’s or Kid’s view. These two are a bit different.

Fitbit Ace App

The Kid View let’s them track how many steps they have done and how many minutes they have been active for. Also adjust goals and check their sleep patterns. They can also active solo virtual hiking challenges and group activities. They are then rewarded for achieving their goals.

All of these group activities can be done with people who are added to the Family account. Which means that your kids can’t add random people (or anyone) to the list. Neither can he post any of the info onto social networks. Kids also don’t see how many calories they have burnt.

The Parent View let’s you see absolutely everything that the Fitbit Ace tracks. In addition, you can send messages and applaud them. Plus you can set alarms if they need to wake up at a certain time.


The Fitbit Ace is a great way to check how active your child really is. It also makes fitness fun and interactive by having challenges and being able to set goals. My only problem is that if your child has friends with Fitbit’s as well, then they can’t do challenges together. Well they can but that would require you to add them onto the Family account. Which is something that you probably won’t want to do. But that’s pretty much my only problem with it.
