The iPhone Duo, Apple’s first foldable phone, has only been out a week—but already developers have brought forward a suite of apps and games that make the most of its dual displays and hinge mechanics. Whether you’re using the 7.6-inch inner screen, the 5.4-inch outer cover display, or propping it in tent or tabletop mode, these 10 apps show off what the Duo was made for.
Movies, Music & Media That Stretch Beyond a Flat Screen
Netflix intelligently adjusts based on how you’re holding the Duo—closed, open, or in tent mode. It moves playback controls appropriately, offers full-screen landscape viewing in tent mode, and even adapts to the hinge’s bend for a seamless media experience.
Deck-Man brings retro vibes by letting you turn your Duo into a cassette player. Pick a tape from Apple Music, close the device to “play” it, and enjoy mechanical sounds and animations that mimic old school Walkman units.
MD Vinyl mixes nostalgia and functionality. When opened, the Duo shows album art and playlist on the inner display. In tent mode, you’ll see a spinning record on the bottom screen and album artwork above, with a smooth transition between outer and inner displays.
Games & Utilities That Lean Into the Foldable Hardware
Toastie feels like a Nintendo DS callback: build a sandwich then fold the phone to toast it—literally closing the Duo to do so. It delivers playful interaction using the folding design itself.
Delta is a retro game emulator revamped for Duo. When half-folded, it mimics a DS-like setup with dual displays. Closing the device puts it to sleep just like the original handheld.
Tiny Computers lets you turn your Duo into nostalgic machines—Commodore 64s, classic Macs, laptops—all brought to life in tabletop mode with working keyboards, windowed apps, even drawing tools.
PianoFold is a rhythm game played on the foldable display. Tiles cascade toward color-coded pads, while the Duo uses the camera to merge your room into the game’s backdrop. Includes 40 tracks spanning classical through contemporary.
Fineliner is a notebook app that comes alive with Apple Pencil support (USB-C). Sketch directly, type when you want, and even draw the app’s own interface. It’s possibly the cleanest notebook experience yet for Duo’s inner display.
DexFold acts like a digital Pokédex. Slightly fold the Duo to browse stats, move lists, and evolutions. Close it and it looks like a sealed book, or scan Pokémon via the camera. Extra polish in its animations and transitions adds depth.
Why These Matter
This group of apps isn’t just entertainment—they’re proof of concept. They exploit the Duo’s two-screen flexibility, hinge awareness, and outer display options. Some use the inner screen’s width for multitasking, while others fully use fold motions—closing, tenting, half-opening—to unlock features that aren’t possible on any flat display.
