I think it’s cool that when you are setting up the Ace, you can choose your favorite clock face. There are 10 designs you can choose from—five horizontal and five vertical—and they list the hours and minutes in different ways.

Strap can be changed as your child grows. Kids are very fashion-conscious and giving them a childish-looking device will only stop them wanting to wear it.

It’s showerproof and super-light at just 15g, not to mention comfortable. Our tester is pretty sensitive to watches, bracelets and bangles, but she’s been happy to wear the Ace all day, every day. Fitbit knows what it’s doing with the ergonomics and the general feel.

The battery life is stated at five days and we've found this to hold true. Because this is a tracker, there's little variation because you're not asking it to record an activity – there's no heart-rate sensor or GPS location tracking – so it doesn't suffer variable endurance times like some of the more fully-featured adult devices. So yes, a full school week is about right, after which it's a quick charge in a few hours to get it back to tracking.

With the new family accounts, Fitbit is giving parents total control over their kids' social interactions in the Fitbit app. Friends and family members can request to follow your child in the Fitbit app, but you have total control over who sees their activity and can approve or reject followers.

It's a one size band (125mm-161mm in circumference) and according to my niece was easy to put on (but hard to take off), comfortable to wear and crucially didn't cause any of the skin irritations that we know Fitbit bands have had a problem with in the past.

What experts didn't like
To turn on the display, you either tap the screen or flick your wrist. When tapping, it often takes a few times for the Ace to react, and flicking your wrist sometimes doesn’t work.

The Fitbit Ace price is set at $99 / £79.99 / AU$129.95, which is on the expensive end of fitness trackers for children with a lot of the competition being a lot cheaper.

As you might expect, there’s no heart-rate monitor or GPS here.

But it isn't designed for swimming, so if those 60 minutes of activity are spent busting out laps at the local pool, then the Ace isn't for you.
- Pocket-lint
One thing she did complain about though was the fact she couldn't go swimming with it.

An Overview On Fitbits

Knowledge is power, and fitness trackers provide a wealth of health knowledge right at your fingertips — or, more accurately on your wrist. With the right fitness tracker, you can power up a healthy lifestyle and a new you.

As a result, wearable technology, like fitness trackers and smartwatches, are valuable tools to help you achieve your goals. These devices do so much more than tell time or add a pretty accessory on your wrist. They record and monitor movement and fitness-related activities. They track the number of steps taken, distance walked, sleep duration and quality, heart rate and more. Some advanced models have separate modes that enable them to track specific types of exercise and can distinguish between swimming, running and cycling and keep logs of your favorite routes. Then, you can connect and upload all the stored data to your computer or smartphone to analyze and learn from your activities.

It’s not a passing trend either. In fact, the global fitness trackers market clocked in at just under $18 billion in 2016. That value is expected to grow to more than $62 billion within the next four years. Smartwatches, specifically, are driving most of the predicted growth. Some of the leading fitness tracker manufacturers include Fitbit, Samsung, Nike, Adidas, Google and Apple.

Fitbit is one of the most popular fitness tracker manufacturers. The company launched its very first tracker back in 2007. Since then, it has introduced innovative new technology and features. Now, Fitbit offers a wide variety of different fitness trackers and smartwatch models at a relatively affordable price range. There are high-tech models with detailed data tracking for serious athletes, as well as simple watches, like the Fitbit Flex 2, for those dipping their toe into fitness tracking and data. There are also Fitbits made just for children ages eight and up to encourage movement and healthy habits early. Whether you’re trying to make fitness fun for youngsters or start your own health challenge,  there is a Fitbit for everyone and every goal.

All Fitbits are designed to seamlessly track every part of your day — including activity, exercise, food, weight and sleep. As a result, the company says they will “help you find your fit, stay motivated and see how small steps make a big impact.”

They monitor heart rate with PurePulse. The newest watches, like Fitbit Charge 3, Fitbit Versa and Fitbit Ionic, include SmartTrack. This innovative technology automatically senses different types of exercises and records them accordingly in the Fitbit app. For example, if you hop on a spin bike and start pedaling, the watch will begin recording as a cycling activity.

The current Fitbit smartwatches, like Fitbit Versa and Fitbit Ionic, also incorporate apps and features like wallet-free payments, calendar alerts and text message updates. Today’s Fitbits and fitness trackers are so much more than step counters. They also enhance and ease many everyday tasks.

In addition to encouraging healthy lifestyles, Fitbit connects all users in a like-minded community. Here, you can share your goals and find motivation from people around the world. It also offers fun competitions with friends, family or coworkers on a variety of statistics to push yourself farther.

All those Fitbit insights add up to real lifestyle changes. In fact, researchers from Arizona State University discovered that the combination of wearing a Fitbit Zip activity monitor and expressing more mindfulness throughout the week increased levels of physical activity. For a relatively low cost (most models range from $50 to $250), fitness trackers help motivate you to kick-start and stick with a fitness plan, hold you accountable, encourage goal setting and, best of all, can help you lose weight.

Pick the right Fitbit fitness tracker, and you’re well on your way to living your healthiest life and achieving your goals.

DYWM Fun Fact

Fitbit founders Eric Friedman and James Park recognized the potential of wireless technology in relation to fitness and health. With the first product, they “embarked on a journey to create a wearable product that would change the way we move.” More than 10 years later, both original founders still lead Fitbit and help introduce new and innovative fitness technology each year.

However, hundreds of years earlier, Leonardo Da Vinci created what appeared to be the first sketch of a pedometer. Then, in 1788, Thomas Jefferson introduced the first pedometer in the U.S. Historians believe it may have originated from the motion sensor of the Swiss or French watches.
