Google Now is software that acts as an intelligent personal assistant and is the counterpart of the iOS' Siri. It is capable of various tasks such as answering questions, making recommendations, performing actions for web services, and displaying cards in Gmail with information about flight, package tracking, and hotel and restaurant reservations.
However, not all Android versions have this great assistant available. For now, only Android 4.1 and 4.2 Jellybean owners enjoy the privilege to have the Google Now assistance. And because of this, developers made something for users with Android 4.0 Ice Cream Sandwich to utilise the technology.
