Get the closest stops based on your current position, then fetch a time list of the next Bus, Train, Boat, Metro or Tram that arrives there. Just try it, I'm sure you'll appreciate it. 

This is a non official and non profit project by Design Container developer Tommy Vitikka. I found the need for an easy, on the go solution for checking which Ruter-stop was closest and finding when the next transportation would arrive. Using the Ruter API, this was quite a joy to accomplish. 

Give it a like if you find it useful!
