Apple and Nike have a long history, dating back to the 2006 introduction of the Nike+iPod Sport Kit that combined a sensor embedded in special Nike running shoes wirelessly linked to a dongle interfacing with iPod nano hardware to communicate a number of different metrics about the user's workout and to integrate audio feedback. That relationship has continued to blossom, with Nike+ software now built into iOS for more powerful tools on the popular multitouch devices.
While Nike+ GPS has been priced at a consistent $1.99 since its debut, Nike today dropped the price tag entirely for a limited time in celebration of the five-year anniversary of the Nike+iPod relationship.
NIKE+ is turning 5! To celebrate five years of providing amazing motivation to runners around the world, the Nike+ GPS App is free for a limited time.
Nike+ GPS is compatible with the iPhone 4 and 3GS, as well as the second-, third-, and fourth-generation iPod touch, although GPS and other features requiring Internet-connectivity are obviously limited on the iPod touch.
