The point of Google Now is to give you answers without making you search at all. One way it does this is by integrating with your Google account, pulling calendar entries, restaurant directions, sports scores, and more into a tidy at-a-glance package. If you’ve got a flight later in the day, Now will keep your boarding information handy--and send you a reminder of when you need to leave, factoring in real-time traffic data between your location and the airport. On Android, it’s continually running in the background, ready to be summoned up at any moment. And on that platform, it’s tightly integrated with Google Search, not only allowing you to ask for answers by text or voice but also learning from those queries and serving up more relevant information to you based on what you’re looking for.
