Apple’s first foldable smartphone is getting stronger software support. The company says more than 100,000 applications in the App Store have now been optimised for the iPhone Duo.
The update is important because a foldable phone is only as useful as the applications that support its larger display. A big screen can make video, reading, gaming and multitasking better, but applications need to use that space properly.
When the iPhone Duo first reached customers, some users noticed that familiar applications did not fill the entire inner display. Apple says the situation is improving, with thousands of newly optimised applications arriving every day.
What does app optimisation mean?
The iPhone Duo has a regular outer screen for everyday use and a larger inner display when unfolded. Applications need to adjust their layouts when users open the phone.
An optimised application can use the extra space for larger images, additional information, multiple columns and better controls.
For example, an email application can display a message list on one side and the selected email on the other. A video meeting application can use more of the screen for participants and shared content.
Applications that have not been updated may still run, but they may appear inside a smaller area with empty space around them.
Microsoft Word, Outlook and Zoom receive improvements
Apple has highlighted several well-known applications that have been updated for the new device.
Microsoft Word and Outlook have received interface changes that make better use of the larger display. Zoom can show a larger video meeting area, while sports fans can use the official NBA and NHL applications for live games and highlights.
There are also useful applications for users in China, including Bilibili, WeChat, WPS, Tencent Meeting, Alipay, Taobao, Amap and several video and reading platforms.
These examples show why developers need to think beyond simply making an application fit the display. A proper foldable layout can improve how people read, work and communicate.
Apple gives developers new tools
Apple has introduced additional APIs through the iOS 27.1 SDK to help developers create applications for the iPhone Duo.
Applications using standard SwiftUI and UIKit components can automatically adjust to different screen sizes. Developers can also build layouts with multiple columns and move controls to more comfortable positions.
New hinge-related APIs allow applications to respond to the angle of the folding display. This could support special layouts when the phone is partly opened and placed on a table.
For example, a video application could display the video on the upper section while keeping playback controls on the lower section.
These tools should make it easier for developers to build applications that feel natural on a foldable device rather than stretched versions of regular phone applications.
Is the app experience now perfect?
Not necessarily. The figure of more than 100,000 applications comes from Apple, and it does not mean that every application offers the same level of optimisation.
Some applications may have a redesigned interface but still need improvements to animations, controls or specific features. The experience can also depend on the application version installed by the user.
Apple’s progress is encouraging, but developers will need to continue updating their applications as more people use the device.

Passionategeekz Take
More than 100,000 optimised applications is a positive sign for Apple’s foldable strategy. It shows that developers are responding to the new hardware rather than waiting for the category to grow.
However, the real test is how these applications work in daily use. A good foldable needs more than a large screen. It needs software that makes the extra space useful.
Apple appears to be making progress, and the coming months should bring even more improvements.
