The Fitbit Ace 3 is a fitness tracker from Fitbit that was built primarily for children and has a minimum age recommendation of six years or older. It has a more rounded design than its predecessor, a display that is brighter, and a longer battery life – up to eight days, compared to five days for the Fitbit Ace 2 – and because it is water resistant up to 50 meters, you can wear it in the shower or while swimming.
You may have it in either a black base with red detailing or a dark blue base with green detailing. There is a wide variety of watch faces to choose from, and the display is a monochrome PMOLED. This ensures that no two Aces are exactly same. Because it is intended for children, the Fitbit Ace 3 does not monitor everything that a fitness tracker for adults does. For instance, there is no information on the number of calories that are burned, and there is no capability to monitor weight reduction.

Fitbit Ace 3: Design

The Fitbit Ace 3 is shaped like a small, rectangular pebble and is protected from knocks and dings by a silicone ring that encircles it. The Ace 3 has a more rounded design than the Ace 2, which contributes to its more contemporary appearance. It is now available in two color combinations: a dark blue with a green clasp and a black with a red clasp. The clasp is made of plastic and is adjustable. Straps in a variety of colors are available for purchase separately.
The Ace 3 is water-resistant to a depth of 50 meters, which means it will remain on your wrist even when your child is swimming or showering. The strap can accommodate wrists with a circumference ranging from 116 millimeters to 168 millimeters. The silicone band is soft and easy to adjust, and we were pleasantly surprised to find that, unlike the straps of many children’s watches, the Fitbit’s band did not bother the skin of our younger tester, who has extremely sensitive skin.
Fitbit Ace 3: Display and Function
The Fitbit Ace 3 features a display that is both touchscreen and PMOLED. It has a grayscale display, despite the fact that it is exceptionally crisp and responsive. Therefore, if color is important, the watch may not be as desirable as its competitors, such as the Neo, which possesses an outstanding screen and rich animations, and the Garmin Vivofit Jr 3, which is arguably the most comparable to the Ace 3 in terms of pricing and specifications. Both of these watches are available in a variety of colors.
The touchscreen on the tracker is a unique feature for a device of this kind. In contrast to the Fitbit Ace 2, the watch is activated simply by flicking the user’s wrist. Additionally, there are sensors on the side of the watch that are used to select options; nevertheless, users can swipe up and down to cycle through all of the capabilities.
Fitbit Ace 3: Interface

The user interface is limited to the most fundamental function of counting steps and will not overwhelm your children with complex metrics such as heart rate analysis or calorie burn. It provides a selection of whimsical clock faces, which was a huge hit with my children. The animated ones that alter themselves in accordance with the user’s fitness numbers were our favorites. As an illustration, the rocket ship got closer and closer to launch as the step count got closer and closer to its target.
My smaller child couldn’t contain their excitement when, once they’d accomplished their mission, the rocket lifted off with a bang. My observations led me to conclude that a child’s age directly correlated with the degree to which they loved watching these animations. Another element that was enjoyable for our family was the ability to compete with members of our extended family and friends to see who could rack up the most steps in a single day. In order to obtain that extra step count boost, we would frequently find ourselves going for an additional walk around the block.
Fitbit Ace 3 review: Software
In comparison to Fitbit’s ‘adult’ trackers, the Ace 3 only includes a subset of the company’s available fitness and notification functions. It keeps track of your steps, records your active minutes, and analyzes your fundamental sleep patterns, but it does not measure your heart rate.
It’s not widely recognized, but the Fitbit Ace 3 does, in fact, come equipped with sensors that can monitor your heart rate; however, these sensors are disabled and cannot be enabled in any way. This is due to the fact that it is really a scaled-down version of an adult tracker, functioning similarly to the basic Fitbit Inspire 2 but is housed in a casing that is more suitable for children.
Fitbit Ace 3: Fitness tracking
The Fitbit Ace 3’s screen is much brighter, making it easier to read outdoors. The Fitbit app isn’t necessary for your child to view their activity data, but more in-depth information is available there. Because it is designed for children, the Fitbit Ace 3 does not have a calorie counter. Active minutes, a proxy for physical activity, are recorded instead. In addition to counting the number of steps you take, active minutes also include the time you spend in other forms of physical activity, such as leaping, trampolining, skipping, or playing racquet sports.
The in-built three-axis accelerometer and heart rate sensors make this feasible. Testers of a more senior age may try to inflate their activity levels by doing nothing more than waving their arms while sitting on the couch. To annoy the younger sibling who was running around the backyard to increase their step count, our 13-year-old did this on purpose.
Fitbit Ace 3: Battery Life
One of the best parts about the Ace 3 is its battery life. The Fitbit Ace 3’s battery, at least according to the company, can supposedly last for eight days on a single charge, while other smartwatches (often those with color displays) require charging every day.
We noticed it lasted longer than we expected, though this could be because we didn’t use the app as often. It’s impressive, and it’s on level with the previous Fitbit Ace 2, which has a pretty excellent battery life of 5 days, depending on how you use it.
Final Words
The Fitbit Ace 3 improves upon the already excellent Fitbit 2 by providing longer battery life and some next-gen added capabilities for more precise tracking, making it the best smartwatch for children. The watch is stylish and functional, with lasting appeal thanks to the lack of any obvious character or media ties. Even (maybe) teenagers would find it to their liking.
