Nike+ Basketball cannot be used in Airplane Mode. Airplane Mode shuts off all radio frequency communication and thus breaks the communication between mobile device and sensor.
Note: The Nike+ Basketball App is no longer available for download in the iTunes App Store. If you are an existing user with the app already downloaded and installed, you can continue to use the app as you've done in the past. Be aware that if you have the Nike+ Basketball App installed and upgrade to iOS 8, you will no longer be able to use the app, as it isn't compatible with iOS 8.
