Web page developers must adapt the content to a new format. Some email pages and certain websites can be consulted from the Apple Watch itself. In the WWDC presentation we already saw how watchOS 5 integrates Webkit, Safari's rendering engine.
Until now, when the Apple watch tries to show a website, it generally showed it to you on the iPhone, as it had no capacity or is not prepared for this. But With WatchOS 5 it will be possible to check the email in HTML format from the clock. In fact we can also see a version of Safari.
This is really the task that developers who want to have content on the Apple Watch have ahead of them. On the other hand, at the beginning there will be few pages that will provide this service, therefore, whoever arrives first will have won a share of the cake. Well it is true that The version of Safari that we can see on the Apple Watch is very small due to the dimensions of the screen.
Still, the first impressions leave us surprised. We can scroll the page with our finger. Zoom in on the image by double tapping or even access certain functions by pressing on the screen. Instead, we do not have easy access to videos or content that requires extensive processing. The quality shown is equivalent to that obtained by an iPhone SE, therefore, being an ultra drinkable device, it is not bad at all.
Regarding the presentation of the web, It reminds us a lot of the Reader View Mode option that we have in Safari on macOS and iOS. Apple is insisting a lot on web forms, as there is a specific tool inside the watch, which can be invoked. By last, Apple asks the developers of these pages to look at the features of Safari 12, to adapt your page to the new features.
