There has been an announcement by Google that talks about improvements made to the iOS search app. The biggest update seems to be with the incognito mode search, private searching.
Now, you can search within the Google iOS app incognito mode easily. A really neat feature of the update is that you can continue your incognito mode searches where you left off using the Apple Touch ID feature.
When you have incognito mode turned on in your settings, your search and browsing history will not be saved. And for added security, you can enable Touch ID for incognito mode, ensuring that only you can re-enter your existing incognito session if you exit the app.
In addition, Google added the ability to watch YouTube videos directly in the search results of the iOS app. Google also made the “app twice as reliable and less likely to crash,” with some code updates.
