One of the features of the iPhone 5s would be its M7 co-processor, which helps take some load off the A7 chip in a bid to help make things more efficient as well as conserve some battery. One of the apps announced at the iPhone 5s’ launch that would take advantage of the M7 co-processor was the Nike+ Move app and the good news for those iPhone 5s users out there looking to give it a try, you’re in luck as the app has since launched on the iTunes App Store and will be a free download and will only be available for iPhone 5s users.
The app will make use of the iPhone 5s’ co-processor and CoreMotion APIs in iOS 7, essentially allowing the app to track your movements more reliably and accurately while collecting data in the background. Best of all, this can be done even when the phone is asleep and will help contribute to more efficient battery use. The data collected by the phone will then be converted into NikeFuel, which is basically a metric used by Nike to gauge how active you are which can also be used to compare against friends or other Nike+ Move users. This is similar to how the Nike FuelBand works so if you don’t want to spend extra money on the FuelBand, your iPhone 5s should do the trick.
