The Fitbit Ace 2 is a kid-friendly fitness tracker with fun animations to keep them hooked.

Colorful; kid-friendly; and replaceable bands; Animated watch faces; Swim-proof; Motivating goals; badges and trophies

Tracker is prone to falling out of the band; Annoying to switch between child and parent view in Fitbit app; Display prone to scratching

The Fitbit Ace 2 is designed especially for younger children. It's a well-priced if basic activity tracker. It lacks the more advanced health measurements you'll find on the pricier Fitbits but it has enough to motivate a family to up their exercise.

Ultimately the Fitbit Ace 2 is a good evolution of the Ace. The new design protects it a little more, waterproofing is an important addition, it's more customisable and easier for younger children to put on and off - but that important sensor module could do with being a little more secure.

Bigger display does more; Adds timer and stopwatch; Waterproofing; Strap easier to undo; Parents stay in control

Battery life should be longer; Not securely fixed into strap

The Fit Ace 2 is an improvement over the original in every way. Its new design is vibrant and fun, not to mention more durable. The addition of a touch screen also makes for a smoother user experience.

Affordable; Vibrant, kid-friendly design; Interchangeable straps; Fairly accurate fitness tracking; Long battery life

No heart rate monitor

The Fitbit Ace 2 doesn't break the mould for what a kids' fitness tracker can do, but unlike its predecessor it puts everything into a more child-proof package. This feels like a tracker built for kids, but also one that has strong core features and the ability to adapt when Ace 2 owners get bored...

Waterproof design; New goal celebrations; More distinctive look

The Ace 2 is the follow-up to Fitbit's first kids' fitness tracker, the Ace. It's designed for a wider range of children (ages six and up as opposed to eight), at a lower price that parents will appreciate ($69.95; $30 less than before). Although it tracks the same metrics as its predecessor—step count, active minutes, hourly movement, and sleep—it's more durable, easier to use, and has a more versatile design. It's a healthy and motivational way to make sure your kids are staying active. It earns our Editors' Choice as the best childrens' fitness tracker you can buy. The Inspire In Disguise To create the Ace 2, Fitbit has essentially taken the Inspire and tucked it into a new wristband. The beauty here is that when kids outgrow it, they can swap it out with Inspire accessories rather than purchase a completely new wearable.

Adults aren't the only ones who need to move more to stay healthy. The Fitbit Ace 2 features a number of improvements over its predecessor, making it the best children's fitness tracker you can buy.

A welcome refresh that's more appealing to children. We think the module should be more substantially held within the strap, but the addition of a more engaging display and waterproofing makes this a better device than the previous version.

Fitbit Ace 2 for Kids Review – Hello! My name is Isabel Good. I'm a kid, and I was asked by Craving Tech to use the Fitbit Ace 2 and let you all know what I think about it. So here are my opinions about it. I will tell you all of the functions, flaws and all.

Built with the intention of making sure your young ones are as active as possible, the Fitbit Ace 2 improves on the previous model with a more eye-catching design, better screen and improved water resistance. To top it all off, it's slightly cheaper than the original, too.

Colorful design; Changeable straps; Swim-proof;

Feels a bit cheap; Somewhat expensive; App can be fiddly to set up

The black piece pops out and is a horrible design for kids. We have owned it for a little over 4 months. My kid is 7 and can be fidgety at times. Honestly he pops it in and out sometimes. So I guess he stretched it out. So at swimming lessons the pebble came out on its own.
