Cant say enough good things about this app.
As a professional pilot I can say that is is the best app out there for pilots. Forefight is a good competitor but for $199 all it really does is translate meters. Flight plan does everything that foreflight does just better and best all of flight plan is free. Which makes it the best option by far.
