App recommendation

Every year around fall I ask by brother for the weather, in a very particular way. I ask "is it sweater cold outside?" and he would say "what is sweater cold?" What I meant was is it chilly for me to wear a sweater but now I don't have to ask my brother because.... There's an app for that! I have a iPod weather app that tells me if I should wear a sweater or a jacket.... It's called "Swacket" I love this app. I highly recommend it.
