Fitbit One, Wireless Activity and Sleep Tracker

Product information

Kick-start your fitness regime and help yourself stay healthy all year long. The Fitbit One™ is a wireless activity and sleep tracker is with you every step of the way. It tracks your steps, distance, calories burned and stairs climbed throughout the day. During the night it continues to measure your sleep cycle helping you learn how to sleep better, and it wakes you in the morning.

  • Monitor your day with the One™ – this tracker’s aim is to empower and encourage you by delivering real-time feedback that helps you be more active. Why not take the stairs instead of the lift? Or go for a quick walk after lunch? Those steps will add up fast.

  • It is suitably discreet so you can wear it comfortably in your pocket, on a belt or bra and the silicone clip will keep it secure.

  • The rechargeable battery lasts 5-7days before needing a boost ans the device is also rain, splash and sweat proof so you can take it with you whatever the weather.

  • At night you can slip the One into a wrist band and the device will continue to work, measuring your sleep cycle. When you need to wake up the One vibrates but doesn’t make a sound so you don’t have to disturb your partner.

  • Bluetooth connectivity lets you see your stats in no time. The One automatically syncs your data to PCs, Macs, and selected iOS and Android devices. All you need to do is sign up for your free account on and register your device.

  • The Fitbit explains your personal data to you using graphics, charts and tools designed to help track your progress. This means you can get a better understanding of your lifestyle and fitness. What’s more the device will score your quality of sleep and over time you can start to apply what you learn in order to make you sleep more soundly.

  • There is a free mobile app and customisable dashboard that bring all your data to your fingertips. Knowing how close you are to achieving your goals, gives you added incentives to push yourself that bit harder. When you do, Fitbit will reward you with badges for daily, weekly and even lifetime achievements.

  • Log your food, water, workouts, weight, and more using Fitbit’s online tools. If you’re on the move, use the mobile app to do the same. Our expansive database covers food and activities, which makes logging your info quick and easy. Create a Food Plan to eat smarter.

  • Challenge and compete with friends and family on In addition to rooting for one another, you can compare stats and see how your progress stacks up.

Q & As

Fitbit One, Wireless Activity and Sleep Tracker 4.4 5 15 15
a pint sized personal trainer ! easy to set up, a useful motivator that gives quite a lot of fitness detail when combined with the online dashboard. Comfy to wear and seems to be accurate too 06 May 2014
Best Product Out There I did not want to have to carry an iPhone around to monitor my progress during an exercise routine. Fitbit One is great because you can look half way through a walk or routine to see hoes many miles you have walked, how many calories burned, how many steps etc.. With the bracelet or the Nike product you have to wait until this is synched to a mobile device. Interface to MyFitness Pal is excellent and the FitBit One updates via my Mac every time it gets near the PC. If I were buying again - I would buy the same product - that is probably one of the best recommendations you can have. 06 May 2014
A great motivator! Easy to wear and to use during the day; not quite so good overnight as the wristband doesn't always stay on. Fascinating to log on each day and view my activity levels, which has now become an obsessive-compulsive activity in its own right! My Fitbit inspired me to try the Couch25k programme published on the NHS website and I am now starting on Week 4 of this programme, albeit at 'pensioner pace'............ 06 May 2014
More than I expected What a great bit of kit! I was expecting a fairly basic activity tracker but this Fitbit is excellent. The web based interface is great, allowing you to see your steps, stairs climbed, most active minutes, sleep etc but also to log food and water consumption. You set a goal and Fitbit tells you how you are progressing in reaching it. Everything works, its simple and intuitive. The only down side is that the food database is not available in UK version so you have to use US. (At the moment) Great buy. 18 February 2014
FitBit One - some reservations Good points: Works well as a pedometer. The online interface (Dashboard) shows all the recorded information clearly in graphical form. Bad points: The Floors feature (to monitor stair climbs) is hit & miss - it is not capable of detecting staircases/climbs of less than 10 feet - i.e. most modern domestic staircases. And, even then, I have found that it doesn't detect larger stair climbs reliably although it does detect uphill walks (and when cycling uphill!). Requires care when clipping onto clothing - can detach easily. I tend to keep it in my pocket now. Conclusion:I use it as a means of making only general day to day comparisons of my activity levels for which it is useful, but in my experience it is not a particularly accurate or discerning device so somewhat disappointing. I haven't tested the Sleep feature. 07 February 2014
What a great present I bought this little gadget for a close friend for Christmas and what a great present it turned out to be. He can't stop looking at the result. It has inspired and encouraged him to get active and fit and was just the sort of motivation he needed. Simple to use and easy to download the info onto your PC, laptop, tablet or 'phone. I don't have one myself but am very tempted. I will have to drop big hints when it's my birthday! Worth every penny. 14 January 2014
great product I received this as a gift. Initially I did not think this would be for me but I love the product and find it really motivating. It will also solve a few xmas presents this year. Highly recommended. 09 December 2013
love it A really effective and easy to use device which has helped me lose weight steadily when previously I had made little progress. It inspires me to be more active. 24 July 2013
