We all knew the new iPhone would have a folding screen. Here’s what people were most curious about and what Apple delivered tonight in the Surprise and Shine event.
Foldable phones have been around for years, so Apple wasn’t introducing a new hardware category with the iPhone Duo. The bigger challenge was showing why an interface that changes shape could be useful.
Apple’s innovation goes far past stretching an iPhone app across a larger screen.
App layouts and controls adapt to the available space. Split View allows two apps to run side by side. Users can open two windows from the same app, quickly switch between them and save useful app pairings to return to later. The third-party examples make the opportunity clear. Zoom can show shared content alongside other participants. Slack can expose more of a workspace. Netflix can offer different experiences across the outer and inner displays.
Even StandBy takes advantage of the physical format, using the partially folded device as its own stand.
For product designers, this is exciting because it adds another layer and a new dimension to responsive design.
We’re accustomed to considering how an interface changes across screen sizes and devices. The Duo introduces a product that can change size, orientation and working mode while someone is actively using it.
The challenge is preserving context as the interface changes. What stays in place? What moves? What becomes available? How do you make the additional space improve the task rather than simply fill it?
So what’s the uptake going to be like? It’s worth remembering what happened when Apple introduced Liquid Glass with iOS 26 last year. The initial response was hardly positive. Yet its influence is already increasingly visible across new websites and digital products.
That doesn’t necessarily mean the criticism was wrong. It demonstrates how quickly a controversial design language can become familiar when it is backed by a platform at Apple’s scale.
The same may happen with the interaction patterns introduced for the Duo.
Apple’s real influence may not be persuading everyone to buy a $2,000 foldable phone. It could be establishing conventions for adaptive interfaces that designers begin applying far beyond this one device.
Will the iPhone Duo change what people buy, or how we design?
