          Fitbit Flex vs Fitbit Flex 2 - User Opinions

            Fitness Tracking. The Fitbit Flex 2 is superior in terms of fitness tracking capabilities, because unlike the Fitbit Flex, the Flex 2 is designed for swim tracking, and is fully water resistant up to 50 meters. The firmware also includes swim sensing and a whole host of swim tracking capabilities in the app.Aug 31, 2018

            There's no changing out Flex for Flex 2 bands though, since the sequel is 30% smaller and sleeker. The different form factor makes Flex 2 feel even lighter and less obtrusive on the wrist. There's also a different clasping mechanism that makes putting it on and taking it off easier than the first device.Jun 2, 2017
