What's a great public transit app to use with the iOS 6 Map app?
Edit: Specifically looking for a public transit routing app that can use the Route function from the Apple Maps app.
Update 28/9/2012: There was a recent update to Transit which seems to correct the arrival times issue. So far, I've liked this app the most.
