The iPhone Duo has been on the market for less than three weeks and Apple says there are already more than 100,000 apps built for Apple’s first foldable device.
Susan Prescott, Apple’s Vice President of Worldwide Developer Relations, says developers have accepted and supported the new iPhone Duo and created some remarkable new apps and upgraded existing apps to suit the new form factor and layout.

“It’s been wonderful to see how quickly developers have embraced iPhone Duo, and we’re grateful for their creativity and innovation,” Susan Prescott said.
“Today there are well over 100,000 apps built for iPhone Duo already live on the App Store, and thousands of optimised apps are being added to the store each day.
“In the last month alone, thousands of developers have joined us for workshops in 19 cities around the world to experience iPhone Duo firsthand and bring updated apps to their users.
“The enthusiasm has been incredible, and we’re excited to see the pace of updates continue to accelerate as more and more apps optimise for iPhone Duo.”

Developers have taken advantage of the already supported iOS 27 and resizable iPhone apps that can make the best use of the larger inner display from day one.
New and updated APIs in the iOS 27.1 SDK make it easier for developers to adapt their existing apps for iPhone Duo.
Apps using standard SwiftUI and UIKit components adapt automatically to each display and move controls to the side within easy reach of the user.
Microsoft has rolled out updates for Word and Outlook to offer a desktop-like experience for the iPhone Duo while Zoom has transformed the inner display into an immersive video conference room.
Sports fans will also appreciate the NBA and NHL updates, which allow them to watch live games and highlights on the larger inside screen of the iPhone Duo.
Productivity apps, including Goodnotes and Extra, are also utilising the extra room of the larger iPhone Duo display.

There are several Australian-developed apps that have already been optimised for iPhone Duo, including ANZ Plus and MyGov.
More than 2,000 developers have attended more than 50 in-person workshops in 19 cities worldwide to experience iPhone Duo firsthand and update their apps and games.
The App Store has created a special section for iPhone Duo apps and games. The iOS 27.2 update has added Apple Pencil USB-C support so users can draw in apps like Procreate Pocket, take notes in Fineliner, TypeDraw, and Apple Notes, and mark up documents in apps like Preview.
