Fitbit ’s One is arguably one of the best activity tracker available today and , yet , less than seven month since it hit the street , Fitbit has decide that a stripped down version worn on the carpus was something the market ’s been clamoring for . Back in ’ 77 , Bert Lance first utter the immortal phrase “ If it ai n’t break , do n’t fix it . ” There ’s a cause we still say it today .
The Flex is a paradox in that it define a handful of gripes users have had with the One but also manages to whole shit the bed . It ’s quite the enigma .
Design
With the popularity of the Nike FuelBand and , to a lesser extent , the Jawbone UP , it ’s no surprise that Fitbit prefer to fast - caterpillar tread a standardised machine . When you ’ve cornered a market for the better part of the last four old age , what do you do when troupe with more money start escape from you down ? In this case , manifestly , you start copy them .
Fitbit’sOneis far less sexy and much , much dorkier than its direct competition . Mainly because it ’s meant to be clipped onto your belt , bra or shoved into a pocket . And for some reason , the great unwashed tend to suffer them jolly oft . The Flex whelm that dorkiness , but loses a few features in the summons .
Fitbit One Review : A Great Way to Monitor Your Wretched Laziness

It still counts your steps and psychoanalyse your sleep , but it can no longer tell when you ’ve gone up a flying of step . Nor can it communicate any data , like the time , instantly to you from the gimmick . You ’re now relegated ( or force into ? ) to use your smartphone , assume you have an iOS or Android machine , to see what ’s in reality happening . Fitbit sacrifice both the video display and the altimeter sensing element from the One to make it more of a wearable , which has its pros and cons .
A series of five midget LEDs are now the only visible cue as to whether you ’re getting close to strain your end for the day ( there ’s a default , but you could also go under your own goals online or through the app ) . To crack your progress , you tap the top of the Flex twice . When you ’ve reach out your goal , the Flex light up up and buzzes . Aside from the occasional spark of its LEDs , the Flex basically look like a flimsy pitch-black bangle or charity / organization watch bracelet . It ’s so minimalist and unassuming that I ca n’t get myself to say that it ’s ugly . It ’s just … there . The clench , for good or bad , makes it objectionably impregnable on your articulatio radiocarpea and there ’s no risk of ever lose it the way you might misplace the One or the cap of the UP .
Using It
Unlike the One , you’re able to never really leave the Flex since it ’s on your wrist and is waterproof , and depending on how combat-ready you are , need only be turn on every five to 10 day , though it can go longer . Like the FuelBand or One , the Flex syncs over Bluetooth to either your computer via a USB dongle or to your iPhone or Android twist . you could even change data point over NFC , if your Android equipment patronise that sort of wizardry . The accompanying app remains the same from previous versions but the screen background site has been revamped for a more visually stimulating experience . ( Yeah , it looks a little bit like Nike ’s Plus portal . )
base onprior research and testingnearly every single democratic activity tracker ( Nike FuelBand , Fitbit One , Larklife , Striiv Play , Jawbone UP , Basis B1 , BodyMedia FIT ) available over the last yr , I compared the One versus the Flex as the former most accurately tracks the number of steps take — the core function of bi - pedal trailing devices . This is of import to note because the One adopt into explanation the number of stair climbed to calculate calories burned , and the Flex has done away with the altimeter . The whole point of these devices is to facilitate quantify some semblance of your overall health . Sleep analytic thinking is something that does n’t factor into my evaluations of these types of activity trackers because I ’ve find them to be inaccurate for a number of reasons . Some people just suck at sleeping , like me , or you just twitch a lot , which any gimmick with a 3 - axis vertebra accelerometer will understand as an interruption in sleep . ( To set off sleep mode on the Flex , you tap the gadget five or so times and the same to waken it up . )
Looking at the number ( steps , aloofness , calories combust ) , this is how the Flex compared to the One :

Over the course of action of four days , the bit of step tracked on the Flex versus the One deviate from as lilliputian as a few hundred to several thousand . Oddly enough , on days that I work out , like Day 3 , the Flex ’s routine are more inline with that of the One , than on days when I do n’t go to the gymnasium . Which is theexact oppositeof what I thought would happen . I received the Flex during the middle of Day 1 , which is why distance and calories burned were throw out .
Fitbit Flex Hands On : The King ’s Reign Might Be Over
Like
Well , the Flex is finally a wearable in the sense that you do n’t have to fret over its whereabouts , shelling life story is quite expert and for its lack of pizazz , it can middling much go with any outfit . There ’s also a wealth of third party apps that you may bind into your Fitbit account for more data scraunch , like Run Keeper , My Fitness Pal and Lose It ! .
Dislike
There ’s no display or altimeter , and the silent alarm function still has n’t been modified for use as an idle alert like on the Jawbone UP . And based on the numbers , it ’s not as accurate as its predecessor and is less motivating because of its minimalism . The bantam windowpane in which the light-emitting diode shine through on the stripe itself are susceptible to the tiniest of dinero , too . While there ’s no backsheesh to lose like with the UP , if you lose the Flex ’s charger , you ’re SOL until you may get a replacement . The USB dongle could also be easily misplaced but at least you may synchronize over Bluetooth to a mobile machine .
Should You Buy It?
price at $ 100 , the same as the more full - featured One , I do n’t bed why anyone would desire to buy the Flex . It ’s inaccurate , has few feature and is the least motive bodily process tracker of those uncommitted today . To be honest though , if you ’re relying on a equipment or app to get you displace , then you ’ve got a whole unlike set of issues to make do with . If a friend were to expect which activity tracker they should grease one’s palms , I ’d recommend the One orBasis B1before the Flex .
