About

One question, answered well.

Does this app work on iPhone Duo? We answer that for the apps people actually use — with the evidence, and the date we last checked.

iPhone Duo is Apple’s first foldable iPhone. Every iPhone app runs on it, but on the 7.6-inch inner display apps look very different depending on whether their developers have updated them. Apple doesn’t publish a list, so we built one.

How it works

We track the most popular apps and games on the US App Store, plus the apps people ask about, and refresh their details every day.
An app only gets a status when there’s public evidence: an Apple demonstration, a developer announcement or release notes, press coverage, reviewed owner reports, or our own testing.
Every page says how confident we are and when we last checked. Read the full methodology.

Independent

WorksOnDuo is an independent site and is not affiliated with, authorized or endorsed by Apple Inc. iPhone and iPhone Duo are trademarks of Apple Inc., registered in the U.S. and other countries. App names and icons belong to their respective owners.

Statuses are never paid for. If we ever show sponsored placements, they’ll be clearly labelled and kept separate from the data.
