FitBit Flex review

 

The Flex is sleek, simple, and fun to use, but shouldn't be mistaken for serious fitness technology.

What we discovered after two weeks of fitness tracking is that the Flex is a stylish, attractive recorder of general activity and motion. For people who aren’t already following a consistent, organized, exercise program, yet want to make sure they’re...

Review: Fitbit Flex

 

Activity trackers are abundant right now, but none are better than the Fitbit Flex -- the most wearable, best-syncing device in the scrum, with the...

Great design. Best smartphone app of all the trackers on the market (Oh, and it’s on Android too). Amazing battery life. Scoble-proof: You can wear it in the shower

Thanks for telling me what I’ve done, but please tell me more about what I should do. Would be nice if device itself showed number of steps taken at a glance

Fitbit Flex review

 

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.

Wireless syncing over Bluetooth 4.0 ; Convenient, simple LED display ; Competitively priced ; Clean, attractive design with multiple color options

Sleep tracking is inconsistent at best ; Database of nutritional data is disappointing

The Flex is entering an increasingly crowded marketplace. Wrist-worn fitness trackers are a hot commodity right now and making your mark in the field is becoming quite difficult. But Fitbit might just have struck the right balance between price,...

Fitbit Flex

 

With a svelte design, low price and a well-developed app ecosystem, the Fitbit Flex is the best all-around fitness-tracking band available.

Minimal comfortable design; High level of customizability; Comprehensive suite of applications; Wide range of connected devices and services

Android app a bit buggy

Click to EnlargeThe Fitbit Flex brings all the types of tracking tools needed to manage your path to better health, and, at $99, costs $30 less than the Jawbone UP and $50 less than the Nike+ FuelBand. The Flex is also the most comfortable gadget in...

Fitbit Flex

 

Among wrist-worn activity trackers, the Fitbit Flex is the best and most competitively priced one you'll find. If you're not stuck on wearing a bracelet, though, the Flex's close cousin, the Fitbit One, is the obvious choice.

Excellent battery life. Accurate. Comfortable, light, stylish. Includes silent vibrating alarm. Interchangeable bands available in several colors. Bluetooth and NFC-enabled wireless syncing to smartphones. Great Web experience.

Limited display of information on device. No altimeter.

For my money, the Fitbit One remains the best activity tracker on the market, and our Editors' Choice. But if you'd prefer to wear a tracker around your wrist, don't hesitate to order a Fitbit Flex.

Fitbit Flex review

 

For a little over a month, I've been getting off my subway one stop early and walking the rest of the way home. I've been playing soccer twice a week, and trying to drink eight glasses of water...

Light and thin ; Long battery life ; Wireless syncing ; Accurate and consistent

Boring design ; Doesn't tell you what to do with your data ; Hard to put on and take off ; Inputting sleep, food, and activity is a lot of work

Fitbit still hasn't answered the 'now what?' question

Fitbit Flex ( slate)

 

The Fitbit Flex is a simple way to track steps, sleep, and calories. The Flex's strap design makes it light and comfortable to wear. It also offers handy Bluetooth syncing, and Fitbit’s platform gives plenty ways to analyze your stats.

Clasping the Fitbit Flex’s strap shut is tricky. Direct syncing is only available with the iPhone, the Samsung GS3, and the Galaxy Note handsets.

A long list of features and a comfortable fit make Fitbit’s new Flex the best fitness tracker you can buy.

Fitbit Flex review

 

The $99.95 Fitbit Flex is the newest personal fitness tracker in the company's lineup. While the Flex isn't without some flaws, the gadget is the most complete product of its kind you can buy. It can track steps taken, sleep quality, and it syncs data...

Fitbit Flex Review

 

If headsets like Glass are pushing the wearable computing boundaries, then fitness monitors like the new Fitbit Flex are entry-level cyborg tech for the mass market. Announced back at CES 2013, and taking on Nike's stylish Fuelband and Jawbone's...

In some ways, the Fitbit Flex is the best mainstream health tracker out there. It’s the most comfortable, has the best balance of wireless connectivity and battery life, and – for daily fitness recording, anyway – does exactly what you want to to,...

Fitbit Flex Review

 

If you didn't realize it before, CES 2014 ushered in the proliferation of the wearable fitness tracker, as several big and small companies announced their models that are on schedule for this year. Already having its feet wet in the category, long time...

It has a very minimalist design ; Water resistant ; Available in a variety of colors ; Mobile app is extremely comprehensive

Proprietary charging port ; Misinterprets hand movements as steps sometimes

Fitbit has been in the game of making fitness trackers, so they have the experience to deliver quality products to the table – and the Fitbit Flex is undoubtedly one of them! It’s stylish, yet discrete, so it’s wonderful that it’s something we can wear...
