The Nike+ Training App is no longer being updated or maintained, and it is no longer compatible with the latest iOS version. For that reason, we've made the decision to remove the Nike+ Training App from the iTunes App Store. It is no longer available to new users.
Existing users who already have the app downloaded and installed are welcome to continue using it indefinitely. If you are an existing user, please be aware that if you choose to upgrade to iOS 8 on your mobile device, you may lose significant functionality on the Nike+ Training App.
