There are more than a few fitness trackers on the market and picking one to suit your workout goals can be a cumbersome task – but it doesn’t have to be. Below, we lay out the major differences between two trackers on the market — the Fitbit Flex and the Jawbone UP — to help you get the best deal for you and get exercising faster.


Both the Fitbit Flex and the Jawbone Up are designed for you to wear on your wrist at all times, even while sleeping, so you want to be sure you are selecting a tracker that is going to be comfortable while wearing it. Let’s take a look at the various design details.

The Fitbit Flex is made with an elastomer material that is similar to what is used to make sports watches. The Jawbone UP, on the other hand, was melded out of a hypoallergenic rubber. Both are latex-free, but if you are susceptible to allergic reactions, you may want to consider the Jawbone UP.

Also when it comes to design, the Fitbit Flex and Jawbone UP feature different securing mechanisms. The Fitbit Flex can be fastened around your wrist with a clasp that lines up with your wristband while with the Jawbone UP, you simply need to slip it on. If you want the ease of just slipping on your fitness tracker, go for the Jawbone UP.

Both the Fitbit Flex and the Jawbone UP come in several sizes and also colors.  The difference is that the Fitbit Flex was made to allow you to swap out band colors depending on your mood or your outfit.  For versatility when it comes to color, you will want to purchase the Fitbit Flex.

You will also want to purchase a Fitbit Flex if you plan on getting your tracker wet. While both the Fitbit Flex and Jawbone UP are made to get wet, the Jawbone UP is only splash resistant while the Fitbit Flex is water resistant and will hold up in the shower and can be submerged up to 10 meters.


Perhaps the biggest difference between the Fitbit Flex and the Jawbone UP is Bluetooth technology.  The Fitbit Flex is able to wirelessly connect with your IOS or Android phone or tablet, as well as your computer to display all your tracking data.  The Jawbone Up, however, does not have that same capability. To view your Jawbone UP data, you will need to plug it into your cell phone using a headphone jack and if your cell isn’t compatible with the Jawbone UP, you are out of luck since the Jawbone UP can’t be used with your computer.  If you are looking to view all your fitness data with a quick click, you will absolutely want to choose the Fitbit Flex.

Battery Power

The Fitbit Flex and the Jawbone UP both come equipped with rechargeable batteries, but the Jawbone UP features a battery that will last your five days longer than the battery that arrives with your Fitbit Flex.  When it comes to charging, the Jawbone UP will also take less time; typically 80 minutes compared to the three hours it will take your Fitbit Flex to charge.  If you don’t mind waiting for your battery to charge, you may want to consider the Fitbit Flex, but if you want more power faster, you will want to buy the Jawbone UP.


Price is always important no matter what you are buying and when it comes to the Fitbit Flex and the Jawbone UP, you will quickly see that there is about a $30 difference between the two. According to Consumer Reports, the Fitbit Flex retails, on average, for about $100 while the Jawbone Up sells for about $130. If you have more to spend, you may want to pull out your wallet for the Jawbone UP, but just keep in mind that for $30 less, you get a tracker, which features Bluetooth technology.
