    It is 30 minutes late. 3 or 4 hours ahead from the current time is very great.

    Seems like googles 15 minutes are more like 5. Went to refund and it was already dead. There is no way that I can find to picl what radar station I need it to display? Shows me one that is 200 miles from me. But not the one that is 15 miles? Will e mail dev and find out if there is a way. Also maybe this app is for europe? Idk. Since its only been a half hour. Il ask about refund.. UPdated Never

    Enables you to get a quick view of the radar plus the other maps. Has tons more features in the free app. I think this app is awesome and you can't beat it for a dollar! For those complaining about the forecast feature remember it is in beta .
