Some guys have apps on their phones that allow them to track the train speed from their seat. Is there an app for android that also collects gradient data? Like if you were a passenger on the Cap Ltd, can you track the gradient that the train climbs as, say, you ascend Sand Patch? Some app that in between button activated starts/stops, it tracks the distance and elevation changes over said linear distance?
