Google Now

Google Now gets you just the right information at just the right time.
It tells you today’s weather before you start your day, how much traffic to expect before you leave for work, when the next train will arrive as you’re standing on the platform, or your favorite team's score while they’re playing. And the best part? All of this happens automatically. Cards appear throughout the day at the moment you need them.

It’s Google’s attempt to create an intelligent, constantly updating, ambient information system.The main feature of Google now comes by way of "Cards" that are presented in a vertically-scrolling list.
