Google Now On Tap can be a pretty useful tool. It allows you to easily extract extra information from the information already on your screen. Now On Tap brings up search results based on what you are currently viewing. There are other features like a share option which allows you to quickly screenshot your screen with one hand.
With the holiday season upon us there are a few extra features which were just added to Now On Tap to help with holiday tasks and errands. You can toggle Now On Tap to view the flight status of a family member you are responsible from picking up from the airport. You can easily check the status of gifts that have been ordered and are being shipped. The update also brings new language options including French, German, Spanish, Italian, Russian, and Korean.
