This time around, Maps is a standalone app available in the Apple Watch app store — a bit of a change from its previous iteration, when iPhone users had to download the Google Maps iOS app then use it as an extension on their Watch.

Several other apps, like Amazon and eBay, pulled their iOS apps' support for the Apple Watch in 2017 without offering an explanation, according to previous reports.

Google (GOOGL) is also rolling out an update this week that will expand its Maps app compatibility with Apple's CarPlay system.
