Fitbit Wireless Activity and Sleep Trackers

These wireless activity trackers keep you in tune with what’s really important: your health. They come in two designs—a discreet silicone clip or an easy-to-wear wristband—to fit your lifestyle. Both designs track your activity and sleep quality, and automatically sync stats to smartphones, tablets, or computers for a real-time view of your progress.

Accurate Measure of All-Day Activity

The Fitbits operate around the clock, tracking the number of steps you take each day and how much sleep you get at night. Even when you’re snoozing away, the Fitbit measures the quality of your sleep and how many times you awaken to strange sounds coming from the closet.

Syncs Stats Wirelessly

With Bluetooth technology, the Fitbits automatically sync stats to smartphones, tablets, and computers, saving you the hassle of inputting the information yourself. Use the included wireless sync dongle to connect to computers. Once trackers are paired with your free Fitbit account, the dongle can automatically sync with devices up to 20ft. away.

Use the Fitbit’s customizable dashboard and mobile app to view charts and graphs of your progress in real time. The easily digestible data also breaks out trends to inspire you to reach your goal.

About Fitbit

When the Fitbit stepped onto the tech scene in 2008, CNET predicted its chances for success were high, saying, “Great idea, great design, great online component. And people need it.” The wireless activity tracker—roughly the size of a flash drive—clipped onto clothing, where it kept track of three things: steps taken, calories burned, and hours slept. These stats synced wirelessly to smartphones or computers, allowing users to set goals and share their progress with friends for added motivation. With this simple recipe, Fitbit managed to do something personal trainers in clown costumes only dreamed of: it made fitness fun.

Today, Fibit has grown to include several models—from the classic clip-on design to a slim bracelet that lights up when you reach your goals. The technology shows real-time progress with easy-to-decipher graphs and charts, and gives out badges to encourage users to get moving.

Didn't come with all the pieces and when I contacted (Groupon) them about it they refused to send the missing piece. I gave it as a gift not knowing ten piece was missing. So I couldn't return it and was obligated to buy the piece. It was highly embarrassing
