The pro version-which costs 50 bucks-seems awesome.
The free version is basically a ton of cool features...all of which require the $50 update. Even a bunch of the seemingly simple features require you to buy Pro. You frequently find yourself saying "THAT costs money too? Seriously?"
If you want to buy the upgraded version, go for it. If not, use TripCase to store your itinerary and a free flight tracking app. Otherwise, youll constantly get halfway through trying to look something up or setting up your trip and get that ubiquitous Pro Version Only screen until you cave and buy it or delete the app.
