Odometer
Using the GPS feature built into the latest iPhone 3G, Odometer will be able to track your distance when or where ever you go! Odometer tracks distance in both Standard and Metric units, and will save your distance until you choose to reset. The large (and simple) Stop/Go button allows for easy reading in even the brightest outdoor conditions. A GPS warning light will turn on in the upper right-hand corner to indicate a loss of GPS signal.
