Perhaps the data is excellent, but the app is poorly written - to the point where I dont know how it managed to get through the App Store screening process. This might pass for a reasonable app a couple years ago, but its 2013 and the bar is higher. Better apps out there for the purpose.
And at least for the carribbean, I find the weather model to be a bit too pessimistic v.s. others.
