Apple names these apps in its October 22 launch announcement. We have not independently confirmed a released Duo update in their App Store notes. They are excluded from the ready count above.

What “ready” means here

We checked 5,836 distinct App Store records using current US charts, targeted searches and developer leads. An app qualifies when its published App Store description or release history explicitly reports iPhone Duo support, an adapted layout or a feature built for the fold. Each entry links to that evidence. These are documented developer claims; we have not tested every app on the hardware.

The directory currently contains 309 qualifying apps, fewer than the original 1,000-app target. Existing listings and targeted discovery searches refresh every hour. The broader catalog is rechecked in rotating batches. New apps are added when clear, released support evidence appears; this is not a complete count of every supported app. Generic iPhone compatibility, device mockups, wallpaper dimensions alone, previews, and unreleased updates do not qualify. Apple’s built-in apps are not used to inflate the list.

“Most rated” uses the total US rating count, with the average rating as a tiebreaker. “Highest rated” requires at least 100 ratings. “Recently updated” uses the app’s latest release date, which may be later than its first Duo update. Free means free to download; subscriptions, in-app purchases and region restrictions may apply.

Apple explains its optimization badge in its Duo submission guidance. Automatic additions require an explicit support or layout statement. Earlier documented support evidence is retained when subsequent notes only mention other fixes. Some widely used apps are still rolling out support.
