Fitbit Flex Wireless Activity and Sleep Tracking Wristband, Black

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

Fitbit Flex Wireless Activity and Sleep Tracking Wristband 3.4 5 40 40
Lasted less than a week Bought this as a birthday treat for myself and after reading varying reviews decided to give it a go. Got it on a Tuesday evening fully charged it and used it fine on Weds and Thurs then got a notification saying battery was low even though the battery should last for 5 days. Recharged and used it on Fri and Sat then on Sat evening without any warning the battery completely died, charged it overnight so it was fully to use on Sunday the battery died without the warning in a couple of hours, charged it again till fully charged once more it died without warning in a hour. When it worked and did what it was supposed to do it was a great little motivator and the sleep monitor is a great function. However I am very disappointed and will be returning this item to John Lewis. 25 January 2015
Inaccurate and dissapointing Having had a old clip Fitbit before that worked well (till it went round the washing machine) I purchased this as a Christmas present. The step counter is very inaccurate - it thinks you've walked half a mile before you've got out of bed. Fitbit teams suggested a few solutions such as entering stride length but nothing worked. The band round the face is also coming away after just a week. I'm returning it and will have to find a replacement present. 06 January 2015
Fit Bit Flex battery Bought this from the John Lewis St Pancras station store and was really pleased with it for the first 3-4 days . Then tried to charge the battery, lights on, great another 4 days then no lights on. Trawled the web for help and found hundreds of reviews saying there is a common fault.The small contacts in the battery to not meet and connect with the usb charger. Done all the test on the Fitbit site but to no avail. Aagh ! I have also email John Lewis but not had a reply as yet. Needless to say I am very disappointed. 29 December 2014
Easy to use! Easy to use, good displays and graphs on the app. Motivates you to do more steps. Can record food eaten but this is for US brands which is a shame! 16 December 2014
poor battery and JLP service Bought the fitbit flex back in August, and it has been a great little motivator. The battery was never fantastic, and lasted 2 days tops. Recently, I was emailed during my second day (lunchtime) without charging, that I had very little power left, and to charge the fitbit immediately. Since then, the battery barely lasts a day, so recording my sleep is now not possible, as I charge it overnight. Contacted JLP about a replacement, and was told to take into a store (not really convenient), to have it checked out, and see if it was repairable. This is not what I expected, nor experienced by the usually impeccable John Lewis Customer service. I was told it could take upto 2 weeks to either repair or replace. Overall, not very happy, and will go instore and ask for full refund. 01 November 2014

Excellent product - recommended I bought this as a treat in my summer-holidays and I have prospered from buying this Fitbit. It is a absolute must have if your wanting to lose weight or simply just to know your personal stats. I definitely recommend this and lots of people in our school have got them and they recommend them to. Good christmas present. I bought these for 2 of my boyfriends and they love them!!! (and we wore them to hollywood!) 16 September 2014
