Nike launches GPS iPhone app

Nike has released its new Nike+ GPS app, which uses iPhone's GPS and an accelerometer for an "accurate, motivating and entertaining runner's tool".

The app lets runners use their iPhone's to visually map every run while tracking pace, distance, time and calories-burned. You also get instant feedback during and after each run from athletes like Paula Radcliffe and Lance Armstrong, and comedian Tracy Morgan. The app also connects to a 3 million-strong community of Nike runners.

Nike says it will continue to evolve the app's digital options over time.

Here's the official feature set:

Run Anywhere: From indoor to outdoor, track to treadmill, this new app combines the power of GPS technology with an accelerometer to map and track a run from anywhere. Even if the GPS signal is not available, the accelerometer will allow the user to continue to track pace, distance, time and calories-burned.

Map Your Runs: GPS technology allows runners to keep track of all their routes including a breakdown of pace and distance at different points during a run. Runners can even tap the screen during a run to see their current location.

Challenge Yourself: The "Challenge Me" feature allows runners to challenge themselves to run farther, faster, or longer than a previous run already logged. The app will also track run history to be able to personalise challenges.

Stay Connected: Runners can wirelessly connect with www.nikeplus.com after each run to instantly save the run and share it with friends via the site, Twitter, or Facebook. In addition, they can view their progress on goals, participate in running challenges and download coaching programs.

Stay Motivated: Runners receive motivating messages from athletes and celebrities when specific customised goals are achieved, challenges are won, or when a personal best is achieved. Runners can also tap the iPhone screen to receive in-run feedback.

The Nike+ GPS App is available now for NZ$2.59 from the App Store.
