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.
Apple named it in its iPhone Duo launch roundup on October 22: it shows more products in the feed, plus buying and order tracking.

In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Shop. 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
- Adaptive layoutRearranges into sidebars or multiple panes on the inner display instead of just stretching.

Questions
Does Shop work on iPhone Duo?
Yes. Shop is built for iPhone Duo — it runs full screen on the 7.6-inch inner display and adapts its layout for the fold.
Does Shop 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 Shop 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.
