The Ace uses a monochrome OLED screen to display information such as the time, date, total steps for the day and total active time. The screen also displays notifications, so your child is constantly being updated on their progress; the little animations that play out given them the incentive to keep active. Having said that, in terms of comfort there were no complaints from our seven-year-old test subject; she found it comfortable to wear and easy to put on and take off. Outside of the unit's touchscreen – which we'll come to later – the only other input on the Ace 2 is a button on the left-hand side which turns the display on and off. It's also a shame that the main body of the device is made from plastic rather than metal; 2018's model felt reassuringly robust and premium, whereas this update comes across as a little cheap and nasty in comparison.

You can also use the Fitbit app to transfer a special watch face to the unit; our personal favorite is 'Sprout', which displays a plant pot that contains a flower which slowly grows as your child builds up their step count throughout the day.

The screen on the original Ace wasn't touch-enabled, and instead, the unit relied on 'taps' for interaction via its built-in accelerometer. The Ace 2 has a touch-sensitive screen which makes a world of difference; there's far more control over the on-screen information now.

The downside is that if you've got a child who is fast approaching their teenage years, they may be a little self-conscious wearing this unit. And at least with the original Ace, you could swap out the strap for a larger one as your child grew older. The straps look playful and appealing, and the whole design is certainly a lot more kiddie-friendly than the rather austere original. s Fitbit Ace may have been aimed at kids, but it was actually based on the company's adult-oriented Fitbit Alta, so it could hardly be claimed that it was built from the ground-up with younger users in mind.

ALWAYS KEEP YOUR FITBIT ACE DEVICE SECURE

Fitbit has changed its approach this year, and the Ace 2 is clearly designed with children as its main focus; as a result, the age range has dropped from 8+ to 6+. There's still not a tremendous amount of stuff to do on the Ace 2 itself, but the ability to swipe rather than tap buttons massively improves interaction. You can set alarms and timers, as well as swipe through your current step count and other health-related goals.
