THE METHOD BEHIND THE DIRECTORY

Two categories.
Evidence behind each.

The catalog labels each app supported or not supported. A developer mention counts as support; the app details explain the evidence.

One device. Three kinds of layout.

01 / Native

Uses the full display.
Built with iOS 27.1+ SDK.

02 / Partial

Fills most of the display.
Built with iOS 27.0 SDK.

03 / Letterboxed

Centered, with empty space.
Built with iOS 26 SDK or earlier.

Public metadata doesn’t expose the build SDK. Release dates bound what’s possible; deployment targets can establish a minimum. An app’s listing in supported devices doesn’t establish its tier. Badge sightings and older release-note mentions are dated evidence. Community badge reports await review and do not change support automatically.
