Fancy a Fitbit, but not crazy about wearing it as a watch?

Enter Fitbit One.

It’s a wireless activity and sleep tracker that clips onto your belt, bag, even your bra, giving you a ‘handsfree’ fitness tracking experience.

For sleep tracking, it attaches to a wristband, so you don’t miss out on the benefits of monitoring your sleep patterns.

Coming in at a shade under $300, it’s a sizeable investment – is it worth the cost?

We’ll guide you through its features so you can decide if it’s right for you.

What You Get in the Box

Open up your new gadget, and you will find:

  • Fitbit One
  • Fitbit One Clip
  • Wireless USB Bluetooth dongle
  • USB charging cable
  • Sleep wristband

Getting Started

Charging your Fitbit One is easy – simply connect the USB charging cable to your computer and away you go.

To start syncing your Fitbit with your computer, you’ll need to head to the Fitbit website and download their Fitbit Connect Software. Once installed, plug in the USB Bluetooth dongle to allow syncing.

Once you’ve entered the code that appears on your Fitbit, the program will guide you through entering your vital statistics to personalize your tracking experience. You can also enter daily step goals and weight loss goals.

Alternatively, most of us will probably choose to sync our Fitbit with our smartphone app. Download from your app retailer, and work through the on-screen setup process.

No dongle required, your phone’s built-in Bluetooth will make the connection and sync automatically.

Now you’re good to go!

Using Your Fitbit One

The technology within the Fitbit may be advanced, but its operation is refreshingly simple.

There is just one button on the top side. Clicking once will light up the display. Click again to begin scrolling through your tracking data. It will show you:

  • Activity: Steps, floors climbed, distance, calories burned and active minutes
  • Clock: One click displays the current time
  • Stopwatch: Hold down the button to activate the stopwatch, press it again to stop

Sync the Fitbit with your computer or app, and it will tell you how you are doing against the goals that you have set.

It shows you your daily average, 7 day total (customizable to other ranges of time) and how many calories you have left for the day.

Where To Clip It

Your key concern with a clip based design is probably where to clip it so that you don’t lose it.

You can clip it wherever you find that is comfortable, safe and will give reliable results. Whilst it’s recommended that it can be attached to your bra, some users have questioned its accuracy in this setting.

The manufacturer’s recommendation is to keep it as close to your torso as possible. Many users prefer wearing it on the hip, either securely clipped to their belt, or in their pants pocket, with the clip on the outside.

If you do choose to wear it there though, just beware when going to the bathroom…. (splash!)

Sleep Monitoring

Clearly, a clip is not the most practical thing to wear to bed.

The Fitbit One comes with a sleep wristband. Soft and flexible, this wide band is not like the watch wristbands of other Fitbits.

It’s worn on your non-dominant wrist and when not worn too tight, is comfortable enough to not be noticeable. It provides the following tracking:

  • Time you went to bed
  • Time it took to fall asleep
  • Sleep pattern
  • At bedtime
  • Actual sleep time

This results in a ‘sleep efficiency’ rating – the higher your score, the better. Monitoring these stats can help you to see what is helping and hindering you when it comes to getting a good night’s sleep.

Key Selling Points

Wondering why you should choose a Fitbit One over one of their other products, or a competitor’s? Here are our key selling points:

Battery Life

We’ve come to accept the daily charging cycles needed for our smartphones, but we expect a little better from our other devices.

Under normal conditions, the Fitbit One will last 14 days between charges. Check the dashboard or head to “Notifications” on Dashboard Settings, to set up an email reminder when it’s time for a recharge.


With its small black body and clips in tasteful tones, Fitbit One is a stylish piece of kit that doesn’t make a statement like a smartwatch or wrist-based tracker might.

If you’re still weighing up whether a smartwatch or fitness tracker is the right way to go for you, check out our definitive guide here.

It can also be worn out of sight, so no-one need know that you are wearing it.

The dashboard on the app and Fitbit Connect software are clear, visually appealing and easy on the eye. Whilst it gives you a lot of information, the sectional design makes it readable and uncluttered.

Silent Alarm

Having a different alarm time to the person sleeping next to you can be a real downer.

With the ‘silent’ alarm it gently vibrates against your wrist to let you, and only you, know when it’s time to get up. This can be customized for different days of the week.


Another great feature of the this Fitbit is how easily it syncs with your devices.

Unlike previous models that had to be manually synced, this automatically syncs with over 200 compatible devices, meaning you have real-time data to hand at all times.

Fitbit Community

As with other Fitbit devices, you can join the Fitbit community, sharing your stats with friends and even setting up competitions to motivate you to get moving.

Along with this are the motivational ‘badges’ system used by Fitbit, that rewards you with badges when you hit certain milestones. This all helps you to continue using your tracker and gives you the motivation to hit your goals.

The Verdict: Should I Get a Fitbit One?

If you’re looking for a fitness tracker that’s discreet, comes with great battery life and a super user-friendly app, this could be a great device for you.

On the other hand, the price tag is pretty steep and you’ll need to weigh up whether the pros outweigh the cons on this one.
