the author of this app says:
FlyBy Nav makes flight planning as easy as tapping in your point of departure, your point of arrival and winds! In one screen, FlyBy Nav displays track, distance, ground speed, time en route, ETA and fuel burn.
Nearly all public airports and navigation aids in the U.S. are stored in its database, so FlyBy Nav knows where you're going.
The U.S. Navaid database is included with this download file. Please visit their Web site for other database files.
