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

Rated 3.5 out of 5 by 48 reviewers.
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
Rated 4 out of 5 by Great product..needs a better fastener. Love my Fitbit, the only issue with this product is it is very hard to fasten, I have to get some-body to fasten it for me,a simple watch type strap would be better.. 24 March 2015
Rated 5 out of 5 by Fitbit Flex Fantastic, I love it and I am taking more steps whenever I can, the only minor problem is the wrist band closure which is a regular tussle! 17 March 2015
Rated 5 out of 5 by part of my life now! Upgraded from the Fitbit one as i kept leaving it on the pocket of jeans or losing it totally and i have got to say this is a great piece of kit if you are trying to up your movement to get fit. Also analysis's your sleep which i find very enlightening and can record weight loss and calories in to manage all areas of weight control. Very much a big part of my life now! 03 March 2015
Rated 4 out of 5 by It's use has been eye opening It turns out I am more active than I thought! I find the dashboard almost compulsive viewing and having a friend has made me very competitive. I was worried about losing the Fitbit while skiing, but it stayed safe. Not risked it in the shower yet, although it says you can. 17 February 2015
Rated 5 out of 5 by Really useful gadget I've been wanting something like this for a couple of years, but the choice of products made a decision on which item to purchase, difficult. The fact that I can wear the Fitbit Flex in a wrist band was one of the main reasons I chose this product. The daily synchronisation is great. To be able to monitor activity and also sleep patterns on a weekly basis is great for comparison purposes. 10 February 2015
Rated 5 out of 5 by Fitbit to keep fit Bought one of these for the wife and me. They don't physically make you lose weight but they do make you more aware of what you are eating and drinking and when if you use them properly. I also use the sleep monitor as I don't sleep well and it tells you how well you slept. It also makes you want to work that little bit more once you start to see little improvements in your weight. I have just bought a bike and downloaded an app to my phone to track how far I go and calories burned. So it's more of a lifestyle aid to getting fitter and slimmer but I would recommend it. You do need to connect it to a smart phone or tablet to get the most out of it. 10 February 2015
Rated 5 out of 5 by Excellent Device Has given my partner the incentive to beat the target, well worth the price 03 February 2015
