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 turns iPhone Duo into a retro cassette player for Apple Music.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Deck-Man. 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.
- Fold awareReacts to the fold — for example, splitting content above and below the hinge when half-open.

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