This is a simple iOS App written in Objective-C that allows you to record your location and movement into a GPX file compatible with XCode. You can then use this GPX file to debug location-based applications, such as navigation and fitness apps.
This app is also a simple example of an iOS location-based application, and it can be used for teaching purposes.
