It would be nice if Sports Tracker had audio, such that, if you are running, whilst listening to music on you Nokia mobile phone and running Sports Tracker it could give you a mile marker indicator without having to take your phone out of your pocket to look at the screen.
This could also be used alongside an ability to input a planned distance for your run and have sports tracker inform you via audio when you are half distance, etc.
This could also then be linked into prvious runs on the same "Route" such that it could give an audio pace comparison, etc.
