Apple Watch Series 3

Hi there !
With the release of Apple Watch Series 3, it seems that the Apple Watch can live its own life without the iPhone, with restriction of using the same phone number (but you can leave the phone at home while being in another location)
Do you know then if it is possible to make running ionic on such a device?

Does the Apple WatchSeries 3 support a WebView in its apps?

Yes it is Apple Watch series supports webView
