This video demonstrates how the LogYourRun iPhone App switches between GPS and pedometer. This is a screen cast showing the iPhone Simulator as well as the Xcode debug console where the app outputs debug information. Initially a location is sent to the app and the app starts using the GPS for measuring distance. Then a series of 13 steps are fed to the application but no more GPS locations. After 20 seconds of not receiving GPS locations the app switches to pedometer mode and rolls up the 13 steps that were taken while the app was waiting for another good GPS signal.
