The new app has virtually the same look-and-feel on both iOS and Android, with Google incorporating nearly all of Now's information cards. 22 of the 29 card types available on Android are making their way to iOS, with airline boarding passes, Fandango, and local events among the missing-in-action.
Google Now is the company's answer to Siri. It is an intelligent personal assistant available for Android versions 4.1 and later. In addition to answering questions, like Siri does, it watches an end user's behavior and delivers -- passively -- information that it predicts the user will want, based on their search habits.
For example, someone that keeps searching for San Jose Sharks results will see results not just for that NHL team, but for others, as well. The results are returned in "cards," and leverages Google's Knowledge Graph project.
Google recently acquired Wavii, a natural language processing startup, and will be incorporating its technology into Knowledge Graph.
Although the apps entered the App Store on Monday, a promotion video gave away the secret last month.
