App's Idea: Get waiting time in bus stations, based on reports of other travelers in the buses.
1. I'm in a bus station, waiting for bus #x or #y (# line bus) . In app, I will set "waiting for bus #x/y".
2. Other travelers which are already in buses on line #x, will set they are present in this line bus.
3. On a map, I will see positions of buses on my desired line(s), arriving to station where I am, via gps of the other travelers. Should calculate aproximative arriving time.
4. Users from bus stations can mark if someone set they are in a bus, but actually they aren't (prevent fake presence)
