Cupertino — Apple Says 100,000-Plus Apps Now Built for iPhone Duo

Apple's App Store now hosts more than 100,000 apps built specifically for the iPhone Duo, the company said Friday, two weeks after the foldable phone went on sale, according to The Verge.

The figure, disclosed in a company statement, marks Apple's first public tally of developer support for the device since its launch.

How many developers have optimized apps for the Duo?

Susan Prescott, Apple's vice president of worldwide developer relations, said the pace of updates is accelerating. "Today there are well over 100,000 apps built for iPhone Duo already live on the App Store, and thousands of optimized apps are being added to the store each day," Prescott said in the statement cited by The Verge.

Prescott called developer response to the foldable "incredible" and said Apple expects more apps to be optimized as adoption grows, per the same statement.

What does "optimized" mean for Duo apps?

Apple has been tagging compatible software with a "Made for iPhone Duo" label in the App Store, a designation meant to signal that an app has been adjusted for the device's dual-screen, foldable form factor. The label does not guarantee a flawless experience.

Have users run into problems with optimized apps?

Yes. The Verge reported that Instagram carried the "Made for iPhone Duo" label at launch but still displayed interface issues on the device. Instagram chief Adam Mosseri acknowledged the challenge directly, calling the Duo "a bit of a tricky form factor," according to the outlet.

The Verge's own review, linked in its report, described the iPhone Duo as "a messy, expensive good time," suggesting that early software support has not fully smoothed over the hardware's unconventional design.

Why does the app count matter for Apple?

Foldable and dual-screen devices have historically struggled with software fragmentation, as developers must rework layouts, navigation, and multitasking behavior for nonstandard screens. A large app library at launch — and continued daily additions, per Apple's statement — signals to consumers and investors that the platform risk of a slow developer ramp is easing.

Apple did not say how it counted the 100,000 figure, including whether it covers apps with full Duo-specific redesigns versus those simply confirmed to run without errors. The Verge's report does not include that breakdown.

What happens next for the iPhone Duo?

Apple said it expects the pace of app updates to keep accelerating as more developers target the Duo's hardware, according to the statement reported by The Verge. Whether that translates into fewer visible glitches — of the kind flagged in Instagram's case — remains to be seen as more apps move from basic compatibility to full optimization.
