How we know
- 01
The build date
Only apps rebuilt with the iOS 27.1 SDK can use the inner display. Apple opened those builds on October 5, so any version released before that is letterboxed.
- 02
The release notes
We read every new version of every tracked app, every three hours, and flag release notes that mention Duo or foldable support.
- 03
Owners like you
Three or more matching reports from Duo owners override everything else. Reports reset when the app ships a new version.
- Built for Duo
- Uses the whole inner display with a layout made for it.
- Stretched
- Fills the screen, but with a stretched iPhone layout.
- Letterboxed
- Opens in a smaller window with empty space around it.
- Broken
- Crashes, freezes or is unusable.
- Updated, unconfirmed
- Rebuilt for Duo, but nobody has reported how it looks yet.
