About Fits Duo
Does it fit iPhone Duo? Check before you open it
Fits Duo tracks which iOS apps are ready for iPhone Duo, Apple's foldable iPhone. For nearly 300 popular apps it shows whether each one fills the inner display, fits only partly, runs letterboxed or has known issues, plus how sure that answer is: confirmed, claimed by the developer, reported by owners, or expected. Owners can rate an app, describe what they see and upload screenshots, and comments and screenshots are reviewed before they appear. A daily check of App Store release notes picks up any mention of iPhone Duo, and developer guides explain how to support the new screen. The site is available in eight languages and is free to use.
