AirportAce is a new application for iOS devices designed to help you navigate the airport. The app is available on the iPhone/iPod Touch (AirportAce) and on the iPad (AirportAce HD). Inside the app, you get a tremendous amount of information, including terminal maps, transportation information, parking, amenities, WiFi availability and even where to find smoking locations.
The app is nice and easy to navigate, and all the information appears to be very up to date. At the moment, AirportAce covers 44 different airports in the U.S. and abroad.
