Common Questions:

What colors does the FitBit Flex come in?

The FitBit Flex comes in black, grey, light pink, light green, dark pink, greyish blue, orange, light white-ish blue, maroonish red, and blue.

Who is the FitBit Flex a good fitness tracker for?

The FitBit Flex is recommended for everyday fitness by FitBit. This essentially means that this device is just for any person to wear around and track what they do. It isn’t meant for “active fitness” or “performance fitness,” which are the other two FitBit product classifications. So basically if you are planning on using this to monitor your active exercise, you might want something else, although the Flex is probably better for exercise than the One or Zip would be. This is more something to wear around all day, including while sitting at a desk.

Can I share stats and compete with friends with the FitBit Flex?

Yes, you can share your data and compete with friends by  syncing your FitBit Flex with your mobile device or computer. Sharing is completely up to you, but if you compete with friends it might motivate you to do more or take those extra couple steps each day. FitBit tries to make the competition feel friendly. You can also send people messages.

What is the difference between the FitBit One and the FitBit Flex?

The FitBit One and FitBit Flex both are typically the same price, and so people are confused about the differences. The two devices are actually quite different. The One is a clip on device that has an OLED screen to display a few of your fitness stats. The Flex has no such screen and must be synced with another device for you to see your stats. The Flex also is a wristband, so you don’t need to clip it onto anything, which could make it easier to wear. Find out more in our FitBit Comparison.

What comes in the box with the FitBit  Flex?

What Others Are Saying:

Terrence O’Brien, Engadget:  “The Flex offers all the features you’d desire most in a fitness tracker while also being more attractive and more affordable than its competitors.”

Nick Broughall, TechRadar:  “While the Flex is starting to show its age a bit, like a fine wine it has actually improved with time. The fact it’s now more affordable is also a welcome one.”

David Pierce, The Verge:  “The $99.99 Fitbit Flex is on one hand the exact opposite of the $129.99 Jawbone Up. The Up is intentionally obvious, a piece of jewelry that also happens to be functional; the Flex just tries to get out of your way as much as possible.”

Reviews:

The FitBit Flex has really been praised wide and far, garnering lots of positive reviews with high scores. It is almost always firmly planted as the best selling fitness tracker on Amazon. In fact, when I see people wearing fitness trackers, I think more often than not they have the FitBit Flex. I think a big part of the popularity of this device is that it is just so comfortable to wear. You kind of forget that it is even there.

Other great features include the fact that this is a FitBit device and uses the great FitBit app. It has sleep monitoring and a sleep alarm. It also works with not just iOS and Android, but also Windows devices. The device also comes in a lot of different colors.

Some problems with the device include that you need to take the device out of the wristband to charge it, which can be a pain. It also can be difficult to close the clasp on the band. The 5 day battery isn’t great (especially considering the Vivofit 2 lasts a year), which is compounded by the difficulty of charging the device. There is no phone alerts and no optional heart rate monitoring. Like a lot of fitness trackers in this price range, it uses LED indicator lights instead of a display.

Despite all the issues I cited, I think the FitBit Flex really achieved its goal of being a comfortable fitness tracker that just plain works and I love the FitBit app. I just wish the Flex was easier to charge or had a better battery. Still, for those interested in this device, I would recommend it, especially given the price, the excellent app, and FitBit’s great customer service. This is a great device for someone that just wants to track their daily fitness stats, not for an athlete looking to boost performance or get detailed breakdowns.
