SAN JOSE, Calif.—At its developer conference today, Apple described its new Apple Watch software features in detail. Called watchOS 6, the operating-system update adds new apps, watchfaces, and features that enhance the ways users are already putting their Apple Watches to good use.

Arguably the biggest update coming to the Apple Watch is the new on-watch App Store. In watchOS 6, you'll be able to browse, purchase, and download apps directly from the App Store on the Watch. That means users don't need to turn to their iPhones to download and install apps that they may have on their iPhones already on their Watches.
