Google's "predictive search" technology enables your device to intuit what you need and search for it without your even having to ask. That technology debuted last year on Android devices, and as of today, it's available on the iPhone and iPad in the free Google Search app. Google's biggest competitor to Siri, Google Now senses what you need and automatically gives it to you on a "card" that pops up from the bottom of the screen. For example, if you're heading to work, it will automatically pop up a card with a traffic update. Or if you're planning to take a flight, it will automatically pop up a card if there are changes to your flight. Google's tagline for the app is, "Right info at the right time."
