Essential fitness data at your fingertips that won't make you look like an astronaut. Compact with a super low-profile, this activity tracker features an optical heartrate sensor for accurate data without the need for a chest strap. On a mid-afternoon run or ride, the integrated GPS receiver accurately tracks your speed and distance. For day-to-day health info, the pedometer tracks steps and calories burnt. Plus, it's hard-wired to push your limits: it learns your day-to-day activity levels, and creates new daily activity goals based on where you're at.
