In addition to refreshing the layout for Communities and Collections on Google+, the search monster today also rolled out an update to its iOS search app.
Available at no charge in the App Store, the native Google search experience on your iPhone, iPod touch and iPad now includes an overhauled voice search interface with a nicely animated logo.
More important than that, the layout of your Google Now cards has been reworked and updated to better organize and surface content for you.
