In order to whet appetites for the new FuelBand SE, which hits shelves on Wednesday, Nike released its companion app, the refreshed Nike+ Move, to the public a day earlier than expected. Exclusive to iPhone 5s owners, the Nike+ Move app uses the M7 coprocessor found in the iPhone 5s to gather information from the phone’s compass and accelerometer. The data is then converted to NikeFuel by the app, meaning that iPhone 5s users can participate in Nike’s fitness ecosystem without necessarily having to purchase a separate piece of hardware like the Fuelband at all. Nike’s proprietary points system, NikeFuel, lets you earn “fuel” through all kinds of activities, more than just taking steps or climbing stairs. Nike describes it as the “first ever single universal unit for measuring all kinds of activities,” and it’s designed to reward you for movement, regardless of your age, weight, or gender.
