The Nike + iPod Sport Kit was jointly announced by Nike and Apple on May 23, 2006 and released on the following July 13th. The kit was superseded by the 5th-generation iPod nano which contained its own accelerometer for use as a.

The Nike+ Sensor could also be purchased separately for the iPhone 3G S through 5 S, which do not require a wireless receiver. The iPhone 6 (and 6 Plus and later) contained its own Apple motion coprocessor and did not support the Nike+ Sensor.
