Google Now has arrived for iPhone and iPad.

Google today released its predictive personal assistant for iOS as part of an update to its existing Search app.

"Google Now is about giving you just the right information at just the right time," Google said in a blog post.

That can include everything from displaying the day's weather as you get dressed or alerting you to heavy traffic along your usual morning commute to updates about stories you've been following and reminders to head to the airport for a flight.

"There's no digging required: cards appear at the moment you need them mostand the more you use Google Now, the more you get out of it," Google said.

Back in October, Google boosted its Search app for iOS with Siri-like voice search. The service taps into Google's Knowledge Graph to allow for more natural-language queries; asking "Do I need an umbrella?" will pull up a weather report, for example.

"Together, Google Now and voice search will make your day run a little smoother," Google said today.

Once the Search app is updated or installed, Google will provide a quick tutorial about Google Now. Sign in with your Google account and it will start providing updates via swipeable "Cards"; tap the wrench icon on the bottom right to select the information you'd like displayed. Users will need iOS 5 or above.

Google Now made its debut last year with the release of Android 4.1 Jelly Bean. There were rumors that it might also be released for the Chrome browser, but it has thus far stuck to mobile. For more, check out Google Now Is Good for Now.
