Pandora has updated their iOS app to give it an iOS 7 sense of style, and has also added an alarm clock feature that allows users to wake up to one of their custom radio stations.
From the Pandora App Store page:
By popular demand, our new alarm clock lets you start your day with Pandora. Pick one of your favorite stations to wake up to – if you like what you hear, you can keep the music playing.
