Nike has updated its Nike+ Running app for iPhone with optimized support for the new iPhone 6 and iPhone 6 Plus screen sizes as well as integration with Apple’s Health app for iOS 8. The new version takes full advantage of the new iPhones so text and images no longer scale up. Integration with HealthKit means the Nike+ Running app can now add NikeFuel data and workout data to the Health app that comes installed on iOS 8. 

In addition to adding data to the Health app, the version can now read heart rate data shared with the Health app as well. Nike says this will support devices like Wahoo’s Tickr products, but apps like Instant Heart Rate that can share data with Apple’s Health app should be compatible as well if you’re less committed to buying hardware.

The update also takes advantage of the new M8 motion coprocessor found on the iPhone 6 and iPhone 6 Plus. This allows Nike+ Running for iPhone to measure changes in elevation and give you credit for inclines during a workout.

Nike also says the new version allows users to start a new run faster than before using a new quick start feature.

Nike+ Running is available for free on the App Store, and you can find more Health-comaptible apps here. Full change log below:

ELEVATION TRACKING Elevate Your Run Nike+ Running is now optimized for elevation tracking for iPhone 6 devices. Accuracy may be variable for iPhone 5s and earlier devices

APPLE HEALTH Connected for Health By accessing your Apple Health data, Nike+ can give you even more detailed information about your run, including heart rate monitor support in-run when using a Bluetooth 4.0 enabled device like Wahoo’s Tickr products.
