The maps it generates look nice. With regard to wind direction, about the only reliable tool to give completely accurate wind info is a bit of fuzz, powder, or fluff when you are at the stand. What is reported or even forecast is sometimes not what you get on the stand. Still, it is nice to have an updated wind/weather forecast on your phone (if I had a smartphone) vs. checking accuweather at home on my computer as I do. I spend too much time on the computer as it is so I choose not to be tethered to a smart phone. Have a cell phone though.
