From its App Store listing:
Yarn Loop is a relaxing and satisfying puzzle game featuring colorful yarn bobbins and knitted patterns. Bobbins move onto the conveyor and collect stitches of their own color. Each bobbin has a capacity value that decreases as stitches are picked up. When its capacity reaches zero, the bobbin disappears. If capacity remains, the bobbin is transferred to the rack and can be used again later. Compl…
On the inner display
Apps built with older SDKs are placed in a phone-sized safe area on a black background. Everything works; you just don't get the bigger screen.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Yarn Loop. 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.

Questions
Does Yarn Loop work on iPhone Duo?
It works, but with black bars. Yarn Loop 1.58.0 is built with the iOS 26.2 SDK, so iPhone Duo runs it in a phone-sized window on the inner display.
Does Yarn Loop 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 Yarn Loop 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.
Why does Yarn Loop have black bars on iPhone Duo?
Apps built with the iOS 26 SDK or earlier run in a phone-sized window on the inner display, and iOS 27 builds can still leave some space empty. The bars disappear once the developer rebuilds the app with the iOS 27.1 SDK — you only need to update the app.
When will Yarn Loop fill iPhone Duo's inner display?
When its developer releases an update built with the iOS 27.1 SDK or later. We read the SDK of every new version of Yarn Loop within about a day of its release and update this page.
What can I do about the black bars until then?
Use Yarn Loop on the outer display, where it works like on any iPhone, or put it in Split View next to another app on the inner display so less of the screen goes unused.
