Yes Dark Sky had the best UI of any weather app I have used.

I now use Weathergraph which does it differently but I would go back to Dark Sky (and pay for it) in a flash.

It shows the correct things and on a phone understands that showing the temperatures across the screen is useless as if I go out I want to know what the weather is like when I might make the journey back in 8+ hours time. I might not care what the weather is in 4 hours time as I will be inside.
