The Brim browser for the iPhone Duo moves buttons and other page elements out from under the camera, so web pages can fill the screen from edge to edge. Developer João Pozzobon built it in response to the complaints about Safari on Apple’s first foldable, and it is open to testers now.
Brim is in public beta on TestFlight, and the first build adds automatic status bar avoidance. Pozzobon says it uses on-device Apple Intelligence to find the elements sitting under the selfie camera and clear them away while the page keeps 100% of the screen width.
Brim uses the full page width where Safari stops at the side controls
Websites put their buttons right under the camera on the iPhone Duo, where the Dynamic Island runs vertically along the side of both displays and the 5.4-inch outer display has a 12MP Center Stage front camera. Brim’s job is to keep those buttons from landing there.
Safari on the outer display keeps web content out of a column on the side that holds the controls and fills that column with the page’s background color. Apple’s WebKit team said in its Safari 27.1 post that it is investigating ways to let pages use that space, and the Safari fix for the outer display has no promised date.

Sites can already push a page behind the system controls with the viewport-fit="cover" meta tag. WebKit found that many sites do not inset all four edges correctly, so text and buttons could end up hidden. Brim sidesteps that by letting the page use the full width and moving whatever would land under the camera.
Space is tight on the outer display, where Safari 27.1 gives websites a viewport as narrow as 382 CSS pixels in portrait. Across every display and layout, the viewport runs from 382 to 951 CSS pixels wide and from 368 to 902 tall.
The Brim browser is TestFlight only for now
You join through the TestFlight link, which needs Apple’s TestFlight app installed first. There is no App Store page or price yet, and the developer’s site has an email sign-up for the App Store release.
Each TestFlight build stops opening 90 days after the developer uploads it, so beta testers will need to update until the App Store version arrives. Apple updated TestFlight with iPhone Duo support the day before the foldable went on sale on October 23, and the iPhone Duo reaches 28 more countries and regions on October 30.
