Get more specific recommendations for nearby attractions
Google Maps' "Explore Nearby" feature works fine when you're curious what sort of shops or restaurants are around you generally, but Apple makes it a whole lot easier to find exactly what you're looking for. When you click into the search bar, a colorful menu appears that enables you to filter suggestions down by Food, Drinks, Shopping, Travel, Health, Transport, Services, and the whimsically vague "Fun." Though if you have to literally look up what's "fun" on a map you may require some more serious guidance.
Know which subway car to get on and which exit to use
Apple and Google each offer much the same in terms of general navigation. But Apple has the upper hand when it comes to transit directions, a brand new addition with iOS 9. Although its city selection is currently limited to the big 'uns, its capabilities make life much, much easier for those of us who ride the subway on the regular.
Beyond giving you up-to-the-minute delay intel and a variety of route options, Apple also provides detailed info about which train car to get on to make the fastest connection, and even guides you to the exit nearest your destination so you don't end up walking a couple blocks the wrong way underground.
