The app is designed to keep track of outdoor activities like hiking and bicycling.

GPS Tracks and GPS Tracks HD for iPad are excellent apps for tracking your outdoor activities, whether you’re running, hiking, biking, or skiing.

Last week, we told you about the launch of GPS Tracks HD for iPad, a follow-up to the popular iPhone/iPod touch app by the same name. We've just received word from the developer that he has released the app two days early. To celebrate, he has provided AppAdvice a limited number of promo codes for some of our readers to get the app for free.

One of the better GPS apps for sporting enthusiasts for the iPhone/iPod touch, is about to arrive as a separate app for the Wi-Fi + 3G iPad. GPS Tracks HD is set to arrive in the App Store on Sept. 8. Here's our first look at this promising product.
