Nike+ has just introduced its latest product, the FuelBand. It pairs with a dedicated iOS app to measure a wearer's daily activity levels, returning metrics such as time, calories burned, steps taken and a newly created NikeFuel. The wristband can display these on its own display composed of 100 white LEDs, but the iOS app makes them easier to understand and allows them to be stored. An airplane mode is present, and the band will store metrics until it can offload them to the website or iOS device. All navigation is done through a single button on the wristband.
