FlightTrack: As adults, we know the frustrations of flying. But the younger kids still find the concept pretty cool, which is why a simple app like FlightTrack can mesmerize your little one for hours. Jonathan Epstein of Celebrated Experiences turns on this app when he's waiting around the airport with his son. "We love playing with the maps. It is great for showing my 4-year-old where we are flying, and what mountains or bodies of water we are flying over." Not to mention, it's a great practical app for parents to keep up to date with flight schedules and information.
