iPhone Duo App Support
Which popular iOS apps have been updated for the foldable iPhone Duo? This is the unofficial official list to find out.
Every app starts as “Not supported” until proven otherwise. Every submission is reviewed by hand, and if it checks out, the list gets updated. Refreshed daily, or as close to it as humanly possible.
Got proof? Submit it here with the app’s name and a screenshot of its release notes, or of the app running on an iPhone Duo.
What do the categories mean?
🟢 Fully supported: built with the iOS 27.1 SDK and fills the whole inner display.
🟡 Limited: updated for iOS 27.0, fills most of the screen with some blank space.
🔴 Not supported: not updated, so it shows up with black borders.
| App | Not supported | Limited | Fully supported |

The app list is a best-effort selection of popular iOS apps, not an official ranking. Apple has not published a compatibility list; status is based on submitted proof such as release notes.
