Re: how long until the apps from my iphone get sync'd to my watch? : Any thoughts?
Seems the iPhone's iOS and the Watch OS are two different operating systems:
The Watch OS comes with it's own set of Apple apps, and the App Store also has apps for watch
(Seems some Watch apps may also be installed on the iPhone.)
The iOS and Watch OS need to be compatible versions to pair and work together ... we can't tell from your post.
Eg: If both have the current versions installed, they are compatible:
Apple Watch 8 can use the current Watch OS 9 version
iPhone 8 can use the current iOS 16 version (iOS 16.5.1)
