Reviews Description: The new Fitbit Ultra Wireless Activity Tracker makes every step you take a step toward better fitness, even on your busiest days. Like the original, the Ultra tracks your day down to details a pedometer canít catch, giving you access to the exact steps you take, calories you burn and distance you travel, along with how long and how well you sleep. And now, with its altimeter technology, Fitbit can track the heart-healthy activity of climbing stairs, encouraging you to take the stairs not the elevator, or walking that hill. The Ultra also gives you more measures to track your fitness (a stair counter, a stopwatch, and fitness achievement badges), and more options (a clock, an iphone app, and new colors). Check your real time stats at any time with a quick glance at your tracker. Itís compact and discreet enough to wear all day long in your pocket, clipped to your waist, or even attached to your bra. Good sleep is another key to good health and weight loss, which is why Fitbit can also track your sleep. Simply slip your tracker inside the included wristband and youíll see how long and how well you sleep. Fitbit wirelessly uploads your data to Fitbit.com whenever youíre within 15 feet of your computer. Works automatically -- no buttons to push, no data to enter. At Fitbit.com, free online tools show how your activity measures up over time and keep you motivated, with no monthly fee required. Track your progress with graphs, see how you compare to others, or compete with friends and family. Plus, you can use Fitbit.com or Fitbitís new free iphone app to log what you eat from our database of over a 100,000 foods, or record workouts from activities like pilates, yoga, or cycling. The Fitbit ultra gives you a clear sense of how youíre doing and encourages you to be more active, because the more you know, the more motivated youíll be. And these small changes can really add up: Fitbit users increase their daily steps by 43% and have lost an average of 13 lbs.
