Keep track of your movement with this Fitbit Flex 2 fitness tracker. It hides discreetly beneath jewelry on your wrist, and it's swim-proof up to 50m for use during water sports. This Fitbit Flex 2 fitness tracker displays LED lights that track your progress and notify you of texts and calls on your paired smartphone.
Before buying the Flex 2, I could not measure my steps in water arobics class each day. I can now get my correct daily steps. I still switch off with my other Fit Bit as that one has a clock, readings of my steps, heart rate, etc. without checking my cell phone.
