  • Fun to Track

    It is fun to track where you are in your steps. The Fitbit App allows for tracking of calories taken in and burned...if you want to use it. Love it.

  • Love my Fitbit

    I just love it and it was easy to put together. Love the sleep tracker. I new I wasn't getting good sleep and what an eye opener when I saw how little sleep I was actually getting.

    The fitbit tracker is great! It fits without discomfort and I can sleep in it without a problem. Tracking my daily steps helps me to locate myself so I know exactly what i'm doing daily! I enjoy it.
