iPhone Duo is the first iPhone that can show two apps side by side, and every app takes part — including Cash App. 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.

Questions

Does Cash App work on iPhone Duo?

Yes. Cash App is built for iPhone Duo — it runs full screen on the 7.6-inch inner display and adapts its layout for the fold.

Does Cash App 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 Cash App 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.
