During the iPhone 5s event launch, Apple showed a Nike app that could track your moves without having to wear a wristband. The moves are tracked through the use of the M7 chip inside the iPhone 5s that measures movement without using that much battery or the main processor.
Nike has released the app to take full advantage of the new processor so that you can track your activity and convert movement into NikeFuel points.
Nike+ Move is available now on the Apple App Store for free. An iPhone 5s is necessary to use the best features in the app. The app can track your movements and show you when you are most active. You can download the app from iTunes here.
