If you are concerned about letting Google in on everything you do, just go ahead and skip this post. If, however, you want to have a lot of useful information right at your fingertips right when you need it, then this post is for you.
Google Now displays cards on your phone with useful information. For example, mine shows me the latest Cleveland Indians score, including the box score if a game is in progress. It tells me when my next appointment is and gives me a reminder 15 minutes before I need to leave, taking into account current traffic. It includes stock tracking, weather information, and other information you want to know about.
Even better, if you use Google Chrome on your desktop, it will give you information based on what you are researching. For example, if you pull up the website for a court on your desktop, Google Now on your phone might pull up a card with the time to the court and offer the option of navigating to it.
Google Now is currently available for Android phones and tablets running ice cream sandwich and jelly bean as well as iPhones. Plus, the beta version of Chrome has a setting to enable Google Now cards, which suggests Google Now is coming to your desktop's Chrome browser.
To enable Google Now on your Android phone, go to the Google app, open the settings, and enable Google Now cards.
