Lots of good data that I'd normally have to go to multiple websites to view,which is nice. What isn't nice is the lack of forecasting and hourly breakdowns unless you pay. A typical phone home screen will give you an hourly forecast for free so I don't see why someone would pay for it. Otherwise,the app is impressively quick to load considering how detailed the map is even though it takes a bit of fiddling to learn what all the buttons do and which data you want to see.
