Nice display, but the forecast doesn't agree with NOAA.

This is fun to look at.

Very cool and sick. Visually awesome and creative. Though the practicality of this spinning thing I wonder vs just the weather app.

Very neat! I like that I get a better “feel” of the whole day’s weather from the ring than most weather apps. But it takes a bit more thinking and interaction to understand how the weather develops. For example, I like to see how the temperature changes during the day and for that, I find a graph illustrates the hourly changes better than just numbers and colors, but the information is obviously available here too. Just requires but more thinking from the user. Are you thinking adding other things like humidity and wind? If so, would you try to fit more information to the dial or add some popups or something else?

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!

This is great. Showing only even hours would be less text, maybe as an option. As I’m looking at it to plan late night activities it shows this mornings forecast where I kind of expect tomorrow’s. Maybe make a continual S curve that can be scrolled by touch? Maybe less elegant, maybe more?

In one word: WONDERFUL

I love this, thanks! Using it reminds me of iPod, what with the rotary navigation of time

Nice! Great use of the mouse's scroll wheel to rotate the dial.

Interesting. Looks like it is not taking into account DST in the US. The time shown for Seattle and New York for example is the non-DST time.
