Fitbit Flex Wireless Activity and Sleep Tracking Wristband, Navy

Product information

Fitbit Flex is the ideal way to track your activity without imposing on your lifestyle. Just strap it to your wrist and leave it there, through day and night and then sync it with your smartphone or computer to see how active you are.

Flex tracks a number of activites to help you evaluate your lifestyle:

  • Steps taken
  • Distance travelled
  • Calories burned
  • Active minutes
  • Hours slept
  • Quality of sleep

Flex measures your sleep and will tell you how long you slept and how many times you woke up, giving you a sleep quality score. Flex can also wake you up in the morning with a silent alarm that won't bother your partner.

You can use the app so set personal goals and then track them as you go by looking at the LED lights on the wristband. You can also sync your stats in real time to see a more in depth breakdown on select iPhones, Android devices and computers.

As well as tracking your activity and allowing you to set goals, the app will also allow you to log food, workouts and more. Fitbit will arrange the data in easy to follow graphs and charts so you can track your progress and set achievable goals. You can earn badges and connect with friends to share and compete and motivate yourself further.

Flex is also water resistant, so it can go out in the rain without risking damage.

The Fitbit app is currently confirmed to work with the following devices:
iPhone: 4S, 5
iPod Touch: 5th generation
iPad: 3rd generation, Retina Display, mini
Samsung Galaxy: S4, SIII, Note II, Note 10.1

Q & As

Rated 3.4 out of 5 by 55 reviewers.
Rated 2 out of 5 by Lovely Idea shame it isn't quite right I was given one of these for my birthday last December. By February I had to return it as it wouldn't sync properly or charge. The wiring in the cable had broken. J Lewis kindly replaced it as the company who make it were useless and make it very difficult to return it - they don't know what customer service is. Now in May my second new one is causing problems as the plastic strap has split and it will need replacing yet again. The catch is a cause of concern as mine does come off my wrist without warning but thankfully I haven't lost it. From a fitness point of view it is very good and I really wish they would sort out the problems with it, develop one that will actually last and is fit for purpose. Lovely software shame the hardware isn't up to standard. Expensive for what it is as it has too many problems for me to consider buying another one. 08 May 2015
Rated 1 out of 5 by Useless fastening I returned this item because I couldn't cope with the fastening - it was impossible to fasten! 28 April 2015
Rated 1 out of 5 by not fit This product was lost once during a run because the fastening is too weak. John Lewis kindly covered it under the guarantee but even the replaced one has been lost almost immediately, also during a run. Unfortunately not a good design and not fit for purpose. Biggest disappointment is that the company itself refused to refund it and instead suggested I join their community! I will not go close to this brand ever again. 27 April 2015
Rated 4 out of 5 by Sleek and stylish Since buying the fitbit flex it has encouraged me to be more active. Focusing on my daily steps it has given me a goal to reach and you can up your goal at your pace. The wristband is slim so unobtrusive and if you reach your target it gives you a little cheer by way of flashing lights and vibrations. Also can be set as a silent alarm to wake you. Love this product and totally recommend to anyone just wanting a gentle nudge to motivate yourself. 14 April 2015
Rated 4 out of 5 by Helping me be aware of my activity Only had this for a week or so. It is already making me more aware of my activity, calorie intake and the net impact on my weight. Lovely and light. Have not had he courage to wear it in the shower though, but I am wearing it all day with no issues and the alarm vibration to wake me (and only me) up makes my husband happy! 14 April 2015
Rated 3 out of 5 by Great but fastening a let down I enjoyed this gadget, the associated app and website. Occasionally it would take a little while to sync and the battery life wasn't the best, but it did the job, except... The fastening isn't at all robust, so after less than two months of ownership I no longer have my Fitbit because it's fallen off somewhere. I can't find it and I resent buying another because I'll be fairly sure it'll fall off again. 10 April 2015
Rated 1 out of 5 by Endless problems My sister bought me this from John Lewis for Xmas. I was so looking forward to it, but it has had endless problems. The battery charging issue as described in many reviews, and now the Bluetooth has stopped working so I cannot sync it - and yes I have tried all the suggested fixes. Would be great if it worked, but just been frustrating and disappointing. 01 April 2015
Rated 1 out of 5 by Poor, poor, poor I bought the fitbit less than 3 weeks ago and it has already broken. Some days it just wouldn't sync with the bluetooth or the battery would completely die despite being fully charged the night before. One day it died, after about 4 hours turned its self back on and then died an hour later. I'm extremely disappointed that the product is so expensive given the number of people who have also had this problem - just look on Google or even rest of the reviews on this website. 26 March 2015
