It happened to me this month. When I travel, I like to make sure my flights are on time, so I like to use FlightView's Flight Tracker. About two weeks ago I purchased another flight status app, and I've been underwhelmed with it ever since.
Now Mac and iPhone Developer Ben Kazez has created FlightTrack, a real-time flight tracker for iPhone and iPod touch. The US$4.99 FlightTrack app (click opens iTunes) uses the same great FlightView data and maps, so it looks and works a lot like the online tracker.
Not only do you get the cool real-time location of each flight, but weather is overlaid on the maps (see screenshot at right). You can track multiple flights, look at details, and search by a number of criteria.
Thanks, Ben. Now I have to spend another $4.99 to replace that other app I'm using....
