Google released a revamped Google Maps apps for Android last week and now IOS users will start to see that update slowly trickle out to them. This new version brings a much more refined discovery and exploration function.
Google Maps for IOS now has an optimized version for iPad. It also brings indoor navigation (for select locations), live traffic updates and a little but more.
Although some users have reported receiving the update, most haven't received it yet (I'm still waiting).
