The live preview

The preview shows your website inside an iPhone-sized frame with your app's colours and tab bar. It's approximate: native parts such as push notifications, Face ID, permission prompts and the splash screen only appear in the real app. TestFlight is the true test.

Some websites don't allow being shown inside other websites. For those, the preview shows a summary card made from your site's title, description and share image. This only affects the preview: your real app loads your site directly and isn't blocked.

Previews are private to you. There are no shareable preview links.
