+1 for flightboard. It is my favorite travel app by far - I can always tell what the arrival flight on any airline is doing based on gate number. This has been extremely helpful in the past, allowing me extra time to contact CS if I know we will be delayed before it's up in the gate area. Highly recommended.

I still have the app on my phone - but for some reason I cannot find it in the app store. Not sure what has changed.
