Ok, I've been getting quite a few inquiries on which weather app I use on my home screen... Of all the things, I wasn't expecting my photo of my weather widget to get that much attention... but it is a beautiful app...I highly recommend it, and even purchasing it if you prefer the other skins only available in the Pro version! :)
It's called Fancy Widgets
Then I download the free MIUI weather skin,
and the free Fancy Digital Clock skin.
