Maps and navigation are bandwidth-heavy, and can be either time-consuming to load; or simmer your wallet in markets that bill you by the kilobyte. By popular demand, Google surreptitiously brought back an offline mode to Maps, only it's slightly different from the way we remember it. You can make Maps cache a portion of Maps around your GPS-pointed location, so it stays on your device, and is accessible in a snap. Google will keep it up to date each time a new point of interest is added to its database. To access the feature, you need to search for the term "OK Maps" using the app's search-box, which reveals a menu item that reads "make this map area available offline."
