While this can make it a tad more difficult to get on and off your wrist, it's more attractive than having a device on your arm that always feels slightly too loose.Īnd despite the Flex's lack of user interaction and lesser capabilities, this can actually be refreshing when compared to its sibling, which is somewhat complicated to navigate. The latter also features a more secure clasp mechanism, as opposed to the fiddly design of the Charge - something which has been a criticism of many other previous Fitbit bands, too. While the Charge 2 offers a black and white OLED screen, the Flex offers a more minimalist, camouflaged tracker which is handy for those looking to keep things discreet. The first noticeable design difference between this duo is the display- or lack thereof on the Flex 2. Here's an in-depth comparison of the two side by side. That's why we're here to take a deep-dive into what the Flex 2 and Charge 2, two of Fitbit's sequel lines, are capable of and how they stack up against each other. With such a range of choice being offered, though, it can be a challenge to figure out which deserves a place in your everyday life. It hasn't stopped this year either, releasing the Alta HR and issuing a beefy upgrade to the Fibit Blaze.

Fitbit went on somewhat of a fitness tracker release surge last year, dropping four models for the activity conscious to strap onto their wrists.
