I am using the public transportation to get to work and every time I need to make a trip I have to look up the time of the next bus either in a paper schedule or on the site. I would love to have an app that just shows the time left to the next bus for my special route right away. One can use google maps api to get the schedules and make it possible to set up a route once and for all. There is a nice site for one specific subway route for a russian university that is a good illustration of this idea http://tutu.mipt.ru/ http://tutu.mipt.ru/
