Day One is a gorgeous journal (or diary) app for the Mac, iPhone, and iPad, and one of my favorite apps in general. It got a massive upgrade timed with OS X Mavericks, and among all its new features is a map view that shows all your entries in Apple Maps. You can view all entries from a specific location, zoom in and create new entries for a location you find, and edit the location for entries with the help of Foursquare.
