It’s a huge rethink of what an iPhone is and could be, and it contains the seeds of many fascinating ideas that might be great in the future.But that future is yet to come.
The iPhone Duo is also one of Apple’s messiest first-generation products in a long time, and right now it will delight gadget nerds and early adopters and likely frustrate everyone else.It’s been a minute since the iPhone has looked or worked significantly differently. The last major change was the iPhone X, which dropped the home button almost a decade ago, and even that was a fairly subtle improvement. In fact, “subtle improvement” is really the entire story of the iPhone — it’s the foundation of Apple’s entire business, after all, and there’s a lot of risk in just up and changing it. You can see it in this year’s iPhone 18 Pro: It’s been refined in many ways, with better thermals and an interesting variable aperture lens, but it’s barely different than the iPhone 17 Pro.But you can’t play it safe designing a foldable.
You have to make some big decisions about screen sizes and what the inner and outer displays are for, and then make an even bigger set of decisions about how that big inner screen should work. All of those decisions are risky, and Apple’s riskiest decision was the Duo’s size and shape.7Verge ScoreiPhone Duo$1999$1999The GoodFun to play withMatte inner display is very coolYou will watch less TikTok on itThe BadYou will watch less TikTok on it because the cover display is too smallHeavier and bulkier than a standard phoneGets hotCameras are just OK$1999 at Apple$2000 at Best BuyHow we rate and review productsApple’s single most important design decision for the Duo was to make it shaped like a passport.The wide aspect ratio makes the inner screen friendlier for 16:9 YouTube videos, but it also marks a departure from the taller foldable design phone makers have embraced over the past five years. Prior to 2026, most folding phones opted for a tall-and-narrow shape to optimize for using vertical apps on the cover screen. But rumors started pointing to Apple going with its landscape-first form factor, and other foldable makers shifted gears — seemingly to get ahead of Apple.
Now that the iPhone and a handful of competitors have adopted the wide format, they have to solve a new problem: designing a cover screen that will work well enough for vertically oriented apps.The Duo’s 5.4-inch outer display is glossy, while the 7.6-inch inner display has a striking nano-texture matte coating. Apple’s very proud of this inner matte display, and for good reason — it looks and feels incredibly solid, a big step up from foldables with glossy, seemingly soft screens with glaringly obvious creases, like the Pixel Fold, and even the more subtle but still visible crease of the Galaxy Fold 8.The matte display is indeed there to help hide the crease, which Apple keeps calling “perceptually flat” because it’s more fun to invent science-y marketing phrases than just saying “you mostly don’t see it.” But it’s true: You mostly can’t see the display crease, although you can definitely feel it. If you’re looking at a white image off-axis, you can see it, and there are moments in some lighting where it’s much more obvious. It definitely shows up more prominently on camera than it does to your eyes.What you will see is the under-display camera, which reflects light in a more glossy way if you’re outdoors or in a bright area.
Overall, though, the camera and display crease stopped being noticeable after a while. The crease also wasn’t any more noticeable after a week of constant flipping and folding, although we’ll see how it holds up over time.That’ll be a real test, because Duo owners are going to be constantly flipping this thing open. Between Apple’s display aspect ratio and iOS design choices, the outer screen feels like much more of a status display than you’d expect — everything about the Duo gently nudges you to flip it open and use it in tablet mode. And not just tablet mode, but portrait tablet mode.
That’s because iPhone apps are largely portrait, and the Duo is still very much an iPhone, even though its shape makes it fight all that history.iPhones have gotten bigger over the years, but they’ve mostly stuck to the same basic rectangular aspect ratios: 2:3 from the first iPhone through the 4S, 16:9 from the iPhone 5 through the 8, and 19.5:9 from the iPhone X on to today’s iPhone 18 Pro. Basically, the iPhone has mostly gotten taller over time.It’s wild to have iPhone apps with controls in all kinds of different placesThe Duo changes all of that — it’s the first iPhone that’s gotten shorter and wider. Both the inner and outer displays have a 1.4:1 aspect ratio, which was a very deliberate choice on Apple’s part, because they’re the same shape open and closed. This is clever in terms of display math and potentially great for app developers, but in practice it means that the outer display is really quite small, especially compared to modern Max-sized phones.
If you’re texting someone in Messages with the keyboard onscreen, you’re lucky to be able to see two or three texts at once.Apple has tried to reclaim some vertical space by scooting the UI elements of updated apps off to the right, but if you’re left-handed, that means using the phone closed with one hand can be challenging, even for someone with big hands. Having that strip of real estate along the right side occupied by navigation controls also means that using the Duo single-handed in your right forces you to reach farther when there’s something on the left side of the screen you need to tap. This means that you’re sometimes holding a fairly heavy phone, stretching for a small target that’s just out of reach, which isn’t particularly confidence-inspiring.It’s also wild to have iPhone apps with controls in all kinds of different places; reaching for the back button in Apple’s Mail app and realizing it’s moved from the top left to the right is kind of disorienting. A lot of using the Duo is just figuring out how to use an iPhone again, which hasn’t happened in a long time.If you’re using an app that isn’t updated for the Duo, you’ll see a black bar along the right side of the cover screen where those navigation controls would otherwise live.
But even updated apps don’t feel particularly useful for anything other than a quick check-in on the cover screen. Apple says you’re getting 90 percent of the screen area of an iPhone 18 Pro, but that’s pretty small for today’s apps. It’s like having an iPhone 5 in a world of iPhone Pro Maxes.This means that when you pull the Duo out of your pocket, you’ll almost always be looking at a tiny amount of information. And the second you want to really do anything, you’ll find yourself unfolding the phone to use the vastly larger and more useful inner display.But you don’t get any additional height when you open the Duo up.
Switching from a tiny portrait display to a bigger landscape view isn’t useful for most phone apps, which are all designed around big portrait displays. Most phone apps look silly this way, especially those still running as standard iPhone apps, which look normal but with lots of black padding on either side. It’s either cramped and tiny on the outer screen or a little silly and awkward when you open the Duo.This means
