Google has updated its iOS search app to version 4.0, which introduces a variety of new and useful changes. The app now recognizes new voice search cues and conversational input similar to the way Siri works. For example, Google says you can ask the app “What’s the weather like?” and follow up with “How about this weekend?” to get results relevant to the weekend rather than the current day. The app will now also alert you when you new articles on certain topics appear. The feature is powered by Google Now, which learns your favorite authors, blogs, and more to provide you with customized alerts. Finally, a few other changes to the app include faster loading, cricket sports data for Google Now, and an updated images search page.
