iPhone Duo apps have surpassed 100,000 on Apple’s App Store, with thousands more arriving daily. Apple announced the milestone Nov. 6, 2026, addressing early complaints about limited software compatibility on its first foldable smartphone.
The expansion includes major productivity, entertainment and shopping applications. Apple says developers are increasingly adapting their software to the Duo’s larger folding display and multitasking capabilities.
iPhone Duo Apps Expand Across Major Categories
Microsoft Word, Outlook and Zoom are among the latest applications optimized for the device. Other additions include NBA and NHL apps, Etsy, LTK, Goodnotes, Extra and the Halide Mark III camera app.
These join previously supported services such as Netflix, YouTube, Instagram and WhatsApp. Apple also identified Spotify, ChatGPT, Microsoft Copilot, Canva and monday.com among applications receiving Duo-focused updates.
However, some announced updates have not reached every user. Spotify, for example, continued displaying compatibility issues on certain devices despite appearing on Apple’s updated list.
Early Reviews Highlighted Software Compatibility Problems
Apple’s announcement follows criticism of the limited number of optimized applications available when the Duo launched in October. A MacStories review roundup highlighted software limitations alongside praise for the device’s hinge and display.
Unoptimized apps can show black borders that waste valuable screen space. Some also place important controls inside overflow menus, making them harder to access.
TechAmerica previously examined the iPhone Duo’s foldable design and its multitasking features. The device supports two applications running side by side on its larger internal display.
Apple Holds Developer Workshops as Demand Exceeds Supply
Apple says more than 2,000 developers attended over 50 hands-on workshops across 19 cities worldwide. The sessions allowed developers to test their applications on the Duo with technical assistance from Apple.
Susan Prescott, Apple’s vice president of Worldwide Developer Relations, welcomed the milestone and said the pace of software optimization continues to accelerate.
The software expansion coincides with stronger-than-expected demand for the $1,999 foldable. Initial inventory sold out within hours, and delivery estimates have extended into 2027.
During its latest earnings call, Apple acknowledged uncertainty about when supply constraints would ease. Meanwhile, additional application updates are expected to reach users as developers complete their compatibility work.
