As we expected, the Android version of the Google Search App now supports offline mode for Google Now cards.
So if you are in a location without internet, such as a subway, somewhere out in a deserted island or just in the middle of Manhattan and you have poor reception (no joke), Google will still show your Google Now cards, even without a connection to the internet.
Google announced this late on Friday on Google+ saying:
Next time you’re on the subway and want to check on your day’s appointments with Google Now, you won’t have to worry about lack of cell service. Starting today (make sure you update your #GoogleSearch App for Android http://goo.gl/idgt3y) your Google Now cards stay loaded, even when you lose service in the subway… or your favorite underground bar!
