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.
In Split View
iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Medium. 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

Questions
Does Medium work on iPhone Duo?
Yes. Medium 4.332 is built with the iOS 27.1 SDK, so it can use iPhone Duo's whole inner display. We haven't seen Duo-specific features yet.
Does Medium 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 Medium 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.
