Not sure what you are looking for but I use Timetable by Watt. This gives me all flights between 2 locations on all airlines. It is formatted like the old paper guides (OGG I think which I am familiar with) this way if I get done early I just bring up the app and see if there is a earlier flight I can get on. Just faster than going onto a web site. As far as I know only available for Android.
On Android, the combination of FlightTrack Pro and TripIt Pro works best for me. They are synched together and provide all needed information. Free versions are also available, not sure about difference in functionality.
