App Store on Your Wrist
One of the most significant changes in watchOS 6 is the addition of the App Store. Yes, that’s right. You can now download apps straight to your Apple Watch, by asking Siri, without even pulling out your iPhone.
This also means that watchOS apps can be standalone, without the need for an iOS companion app. This could open the door for developers to create exciting new apps — and it brings the Apple Watch one step closer to full autonomy.
