FlightTrack is a useful iPhone app for technophiles on the go–it lets you check flight status, locate airport gates, monitor delays, and see real-time tracking maps for flights on your iPhone. Although you could do most of these tasks from different Websites, it helps to have all the functions bundled into one easy-to-use application. Plus, FlightTrack uses real air controller data to track its flights, not the airline-controlled information you get at company Websites. You can also save your future travel itineraries and watch high-altitude weather in routes you’re planning to travel. The regular version costs $4.99 and the Pro version, at $9.99, automatically syncs with the itinerary planning site TripIt.
