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

Fitbit Flex Wireless Activity and Sleep Tracking Wristband 3.5 5 28 28
Problems with the Battery I bought this Fitbit Flex after carefully researching the Activity Tracker market. It was close call between this product and the Garmin Vivofit alternative. I have had it for 2 weeks and I was initially very happy with it. The information it generated had helped to adjust my exercise regime for the better. It did exactly what I expected from an Activity Tracker. This all changed 3 days ago when I noticed the battery was flat. I charged it as required until it held a full charge (four lights on the display). Within a few hours the batter was flat again. This then became a reoccurring theme. The Fitbit battery now does not last for longer than 4-5 hours. I have consulted the Fitbit support site and done all the recommended actions (cancelled all alarms, reset the device and stopped the direct sync with my IPhone). None of this has helped. The batter is rubbish and apparently this is a common problem. Just a quick Google search will show you how many other people have had this problem - the forums are full of people talking about various fitbit battery problems. Maybe there is a faulty batch doing the rounds. I am now very upset by this purchase. I have thrown away all packaging and the receipt and now no longer know what to do with a product that promised so much but ultimately is useless. I should have gone with the Garmin. 26 July 2014
Interesting Product - Poor Quality I found using the Fitbit very interesting and enjoyed analysing my activity together with lots of additional information. Unfortunately after 6 weeks use the Fitbit completely stopped working and the bracelet fell to pieces. John Lewis very quickly arranged for a replacement to be sent the next day, but I wonder how long this will last? 25 July 2014
A neat piece of tracking device Bought this for my wife who had been very keen in trying to monitor her daily routine. The only thing that she was not very happy about is the strap lock which to her it is not too secure. The strap can get undone fairly easily. Otherwise it is a good piece of kit. Definitely would recommend to whoever likes tracking their daily activities. 24 July 2014
Inspired purchase I bought this as a christmas present for my girlfriend, and it has been in constant use. 22 July 2014
Misleading ! I travel the tube to work, I use a keyboard at work, I walk in between these activities and I walk otherwise too ! The Fitbit records vibrations on the tube/train ! Ultimately, I don't really know how many steps I have 'actually' taken during the day ! I don't mind a small error but certainly not this ! Therefore, it's back to Map My Walk for me ! 17 June 2014
Great item, changed my life So interesting to know how far you are walking in a day, makes it easy to up your fitness. Cant recommend this product highly enough 16 June 2014
Not working for me Was really hoping this device was going to be the bees knees but unfortunately it Runs out of battery without warning - apart from an email sometimes Doesn't have anyway of informing you how many steps over your goal you have done Sleep tracking seems complicated and there are better apps on the iPhone Doesn't sync with my iPhone only my iPad Aria didn't sync effectively with either device and couldn't determine which user was being weighed. Really wished I'd returned with the scales!!!! 11 June 2014
Great little item I got this to track how many steps on average I do but it turns out my favourite featured is the sleep tracking. I use it on iPhone & iPad and it's compatible with my fitness pal so I can workout calories in & used. 03 June 2014
