FlighTrack is an app which helps in tracking a flight. You just have to enter your flight number or select a specific route to find your flight and the app will fetch your flight info and send your a confirmation email. The app gives you the status of any given flight and gives estimated times of departure/arrival based on airlines info and current conditions at airports.
FlightTrack Pro also provides detailed info about any airport, such as average delays and weather forecast, a nice feature to help you gauge if your flight will be on-time. The map shows weather conditions such as heavy rains or thunderstorms, another great hint about the status of your upcoming flight. The app costs 9.99 dollars. [link]
