Pretty cool idea and execution. This is the first weather app I can see myself using instead of whatever my phone or google puts in front of me; but I often need more data, mostly humidity and wind speed and direction. Also rain seems to be a boolean, but precipitation percentages would be much more clear.

Having both the dial and the more common horizontal table / graph would make it the perfect weather app for me. Maybe those could be integrated into the dial, like wavy rings?

In any case, nicely done!
