Nike announced the launch of its new GPS App on the App Store as it attempts to build upon its array of digital training tools for athletes.

The app is designed to operate seamlessly between GPS and an accelerometer, allowing runners to use their iPhone to map every run visually. The app also lets users track pace, distance, time and calories-burned. The solution also offers instant feedback during and after each run from celebrities such as Lance Armstrong and Tracy Morgan. The app, through its website nikeplus.com (which has more than three million members), connects users around the world or just down the street.

"We are so excited to introduce the true "Runner's App," for iPhone combining the dynamic power and community of Nike+ with the user-friendly functionality of GPS and accelerometry... We will continue to evolve the digital options we provide to runners so that their running experience is always unique and inspired," said Stefan Olander, VP, Nike Digital Sport.

The Nike+ GPS App costs $1.99 and is available from the App Store for the iPhone and iPod touch. The app supports the iPhone and iPod touch; though the software only functions through accelometer technology on the iPod touch.
