Nike+i Pod
The Nike+iPod Sports Kit is a device which measures and records the distance and pace of a walk or run. The Nike+iPod consists of a small transmitter device attached to or embedded in a shoe, which communicates with either the Nike+ Sportband, a receiver plugged into an iPod Nano, or directly with a 2nd Generation iPod Touch (or higher), iPhone 3GS (or higher) or a Nike+ Sportwatch. If using the iPod or the iPhone, iTunes software can be used to view the walk or run history.
On September 7, 2010, Nike released the Nike+ Running App (originally called Nike+ GPS), which used a tracking engine powered by MotionX that does not require the separate shoe sensor. This application works using the accelerometer and GPS of the iPhone and the accelerometer of the iPod Touch (which does not currently contain a GPS chip). It is free in the App Store.
