Apps for iPhone Duo

Apps that do something on the Duo a flat phone can't. Every app on the Duo gets the bigger screen, so that alone doesn't get an app onto this list. The entries below were added before the 23 October launch, from what Apple or the developer said, including the apps Apple named at the announcement. From launch, I only add an app after using it on a Duo myself. Each entry says what the app does on the Duo, and where that claim comes from.

ComicFlow

Book pose turns the fold into the gutter of a two-page spread, so no page straddles the crease, and folding, unfolding or turning it keeps your page. The library gets a collections sidebar on the inner display. On the App Store since version 3.5 (6 October 2026), built and tested in the iPhone Duo simulator.

A teleprompter that records you. The script follows your voice and waits when you stop. On iPhone Duo it faces you on the outer screen beside the 48MP main camera, while the inner screen is a director's view. On the App Store since 14 October 2026.

Two audiences

Peekaboard

Available

A table of games for two people and one phone: Naval Duel, Bluff Cups and Gin Rummy. In Naval Duel the Duo lies flat between the players, each has one half of the sea, and on your turn you fold the phone up towards you to peek at your fleet. A cover screen between turns keeps the fleets hidden, because the hinge cannot tell which half moved. On the App Store since 13 October 2026; the fold has only run in Apple's simulator so far.

Uplid

Your Mac on the Duo in laptop pose: the Mac screen on the top half through the Screen Sharing built into macOS, a Mac keyboard and trackpad on the bottom half. Book, flat and folded work too. In App Review since 25 October 2026, and I use it on my own iPhone Duo.

Named by Apple at launch

Apple named these apps as taking advantage of the folding design. I'll describe what each one really does once the device is out and I've used it. Until then, the note is Apple's claim, not mine.
