How the status was checked

Automatic check
Every day, from Apple's App Store data: the version, its date, and whether the listing has screenshots made for the Duo.
Duo screenshots
None on the current version.
Hand test
Not tested on a real iPhone Duo yet. A hand test covers five postures: cover, open, laptop, book and tent. How we test

Apple hasn't published the date it started taking iOS 27 SDK builds; we use Sep 1, 2026, early on purpose, until it does.
