From its App Store listing:
If you want to use the full width of your iPhone Duo's external screen in Safari, use Wider. It's a simple extension that lets you quickly toggle websites into full width mode. Use the Wider toggle button in the right navbar to quickly toggle between normal an Wider mode. Wider doesn't work on every website.

On the inner display
The app reaches the edges of the inner display. Text and controls stay a comfortable size instead of being blown up.

iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Wider. Open it on the inner display, then add a second app next to it. You can save the pair and come back to it later.
Duo-specific features
None confirmed yet. Duo-specific features include side toolbars, layouts that react to the fold, and content on the outer display while the app is open inside.

Latest release notes
Version 1.2 · Oct 31, 2026
Thanks for all the great feedback This update fixes some of the initial feedback I received, and makes it easier to submit feedback for websites that are broken. Wider now supports 11 languages. You can report website problems directly from the Safari extension menu. This update also improves website compatibility and makes the Wider button behave more reliably. The next update will add more approaches for handling content that goes underneath the camera, I hope it’s out by the start of next week! - Jordi
Questions
Does Wider work on iPhone Duo?
Yes. Wider is built for iPhone Duo — it runs full screen on the 7.6-inch inner display and adapts its layout for the fold.
Does Wider work on the outer display?
Yes. iPhone Duo's 5.4-inch outer display behaves like a regular iPhone screen, so every iPhone app works there as usual.
Can I use Wider in Split View on iPhone Duo?
Yes. On iPhone Duo every app can be placed side by side with another app on the inner display — developers don't need to opt in. How comfortable it feels at half width depends on the app's layout.
