If you haven't used or read about Google now already it's a personal assistant that uses a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of services on the web. For example it can bring up weather, sports, travel, movie, delivery information and even directions based on what I'm doing or have done in Google's ecosystem automatically, without you asking for it. It really does come in handy.
With the app you'll also get instant answers by speaking with your voice, you can ask things such as "Who's the cast of Iron Man 3?", "How is the weather today?" or directions to the nearest Italian.
You can get Google Now on your iPhone, iPod or iPad right now by heading over to the App Store.
