Fitbit Ultra now motivates you to take the stairs and climb those hills. The new Fitbit Ultra is equipped with an altitude sensor that keeps track of when and how much elevation you gain throughout the day when you walk, run, or bike. Fitbit Ultra will show you the equivalent number of floors, each equal to about 10 feet of elevation gain, that you've conquered over the course of your day. Fitbit Ultra also includes customizable messages and greetings displayed right on the Tracker, which you can configure during setup or later on the site. Several new badges are also available, which reward your floor achievements.
