The app's main new additions come in the way of new search, data management and voice search features. The new search feature will allow users to get back to their search results faster: Once you do a search, click a result and then find out its not what you wanted, when you hit back "your search results will instantly appear, ready for you to choose the next one," Google's Chrome for iOS update post read.
Chrome 29 will also come with an interesting voice search enhancement. Now you can request follow up searches by using pronouns. So for example, your initial search could be “Who is the president of the United States?” and now with the new pronoun recognition, you could follow up with, “Who is his wife?”
Lastly, Google has also given users the ability to view their data savings in Bandwidth Management Settings. At this point, the feature is being rolled out slowly, but according to Google will be available to "all users over time." Other additions coming along with the update include general improvements with security and Single Sign On. You can grab Chrome 29 for free through the App Store now.
