How it works

iPhone Duo launched on 23 October 2026. Apps that are optimized for it carry a Made for iPhone Duo badge on the App Store, which Apple shows once the developer submits iPhone Duo screenshots.

This site tracks that badge for the most popular apps and for anything you search. Statuses:

• Optimized – the app carries the badge, or Apple has publicly named it or featured it in its “Great Apps on iPhone Duo” App Store collections.
• Not optimized – the app has been checked and does not carry the badge.
• Not verified – not checked yet, or Apple does not yet expose a machine-readable signal for it.

App names, icons and metadata come from Apple’s public App Store data and are shown as-is. Popular apps are re-checked several times a day, others daily.
