Very good, worth it.
I am a ramp agent. I love looking at the flight that are on the way. If they are delayed or not. Its a good app. There is a free app from the developer, I am using this one because I am in love with airplanes. I follow flights. If you want to follow a lot of flights then its worth paying since it is only one time.
