Seriously? You're either joking, or the worst "grammar-nazi/pedant/troll" in the world.

This just reeks of desperation, just their way of trying to save face right before Apple kicks them off from the iPhone main screen. It doesn't matter, 99% of users won't even know about this app, they'll just go with Apple's Maps. Even if Google decides somehow magically to introduce turn by turn directions, it still won't matter. Google shot itself in the gut, and they know it. They could have at least kept feature parity with Android, but the fact that iOS Maps app was neglected for years only made Apple react more strongly. Now, Apple controls every main app on iOS (browser, music, maps, messaging). They control their destiny.
