Fold to focus. Unfold to

Fold to focus. Unfold to plan.

The iPhone Duo goes on sale on 23 October. We spent a week laying every main screen of InfiniteUp, our own task partner, across both of its displays, and this is what that looks like.

Closed, it is the phone you already know: today's list, the next step, nothing else. Open, it is the whole plan on two pages: the board, the week, and the Briefing, your day written as a morning newspaper, printed as a two-page spread. Nothing important sits on the fold.

The App Store build made with the iOS 27.1 SDK is live, and the fold works in any browser window sized like the Duo, which is how we tested it before owning one. We are writing the rest down as it happens, dates included: https://infiniteup.dev/iphone-duo/?utm_source=contra&utm_medium=social&utm_campaign=duo-launch

Built with FlutterFlow and Flutter, Firebase underneath. If your app needs to be ready for the Duo before April 2027, when Apple makes Duo screenshots mandatory, that is the kind of week we do for clients too.
