Sometimes you need to find something that you don't want to see listed in your Google search history, even while you're on the go. Chrome's Incognito browser sessions can be good for that, but a new tweak for the Google Search app on iOS makes it easy to open up disposable sessions there too. Additionally, it's set up so that if you leave the app and need to come back to the search, you can lock it using TouchID, so even on a shared device like an iPad, someone else can't easily see what was in there.
Google says that other changes have made the app more stable with 50 percent fewer crashes, increased compatibility with iOS 10 and added the ability to watch YouTube videos within the app. If you find Incognito searching useful, then you can jump straight into it with 3D Touch by hard pressing the search icon.
