Google has updated its Google Now mobile app with movie reviews, cinema tickets and real estate information. In addition, all this information is visible on the lockscreen, meaning that users can use it without having to launch the app or even unlock their smartphone or tablet.

Google's personal assistant - the company's response to Apple's Siri - offers users answers, make recommendations and access web services. Google Now can also send information to users that it predicts they will need.

A device running Android version 4.1 with the app installed will feature three cards on its lockscreen, each of which features information deemed important to the user at that particular moment in time.

"When computers do the hard work, you can get on with the things that matter in life. Google Now helps you do just that, giving you the information you need, before you even have to ask," Google product management director Baris Gultekin wrote in a blog post.

The latest changes will also prompt users when it's time to leave for the theater and will automatically show the digital ticket on the user's smartphone screen as he or she enters the cinema. In addition, the real estate feature can give users the listings of houses and apartments based on their physical location.
