ABOUT THE DIRECTORY
More useful. Less endless.
iPhone Duo Apps is an independent directory built around a simple question: what does this app let you do with the extra screen?
A bigger app icon is not a reason to unfold.
A better task is.
Small collections, clear reasons
The directory separates watching, working and creating. A profile explains the app’s use case, what has been published about it and a practical check to make on your own device. A familiar brand is not enough to earn an “optimized” claim.
Our current edition is source-based. Apple’s announcement supplies the first set of app previews. Developer documentation supplies the framework for understanding screen changes. Every profile keeps the boundary between a preview and a hands-on result visible.
Tools that help finish the task
The 3D mockup studio puts your screenshot on the folding device and hands back the render. The testing checklist gives a future device test a repeatable record. Saved apps and comparisons stay in your browser, without an account.
Editorial ownership
Content is published under the site’s organization name, iPhone Duo Apps. Read the selection method for the review process, source hierarchy and correction policy. This site is not affiliated with or endorsed by Apple. Developer previews are attributed to their sources and are separate from Apple-showcased entries.
App links in this build do not include affiliate tracking parameters. Any paid placement must be visibly labeled and kept separate from what an app has published. The Dashow profile was added at the site publisher’s request, using public developer sources rather than comparative testing.

A good contribution identifies one app, one specific behavior and one public source. Send a suggestion or correction; it is not automatically published.
