Apple opened pre-orders Friday for the iPhone Duo, its first foldable phone and the biggest change to the iPhone lineup in years, and demand was heavy enough that the company's own ordering page briefly went dark minutes before the scheduled 5 a.m. Pacific Time start. Visitors to the Duo's page were met with a placeholder reading "Almost ready for you. Pre-order begins at 5:00 AM PT. See you soon," according to Engadget, before the storefront came back online and pre-orders proceeded on schedule.
The Duo starts at $1,999 for 256GB of storage in the United States, rising to $2,199 for 512GB, $2,599 for 1TB and $3,199 for 2TB, according to a pricing breakdown compiled by MacRumors. It comes in two finishes, Star White and Night Sky, is eSIM-only worldwide, and runs on the A20 Pro chip, the same processor found in the iPhone 18 Pro and Pro Max. Apple's original announcement describes the device as having a 5.4-inch outer display for quick tasks and a 7.6-inch inner display, roughly the size of a small tablet, once unfolded.
Phones go on sale October 23 in the US, Australia, China, India, Japan, Malaysia, Singapore, South Korea and Vietnam, with 28 more countries and regions following a week later, on October 30. Apple is also selling a $79 Duo Case and a $129 Duo Folio with a built-in kickstand starting the same day pre-orders opened.
Apple's Answer to Eight Years of Samsung Foldables
The Duo is Apple's first entry into a foldable-phone category that Samsung has occupied largely alone since 2019. A side-by-side comparison from Tom's Guide found Samsung's Galaxy Z Fold 8, which starts at $1,900, remains noticeably lighter than the Duo, while Apple counters with titanium construction, IP68 water resistance and support for the Apple Pencil on either screen, features the Fold 8 lacks. Samsung, now on its eighth generation of folding hardware, still has the edge in manufacturing maturity; this is Apple's first attempt at a hinge and flexible display it has to support for years of software updates.
One notable omission: there is no Face ID. Apple built Touch ID into the Duo's side button instead, a sensor that works whether the phone is open or closed and can be registered to recognize different fingers for each state. Apple has not given a detailed technical explanation for dropping Face ID, saying only that it wanted one authentication method that functions consistently across both of the phone's screens.
A Premium Bet on a Still-Niche Format
At $700 more than the 256GB iPhone 18 Pro Max, the Duo is priced as a specialist device rather than a mainstream upgrade — the extra cost buys the folding display and dual screens, not a faster chip, since the A20 Pro is shared with the conventional Pro models. Early supply-chain reporting has suggested Apple built a more limited initial run than it does for standard iPhones, and the pre-order rush, however briefly it strained Apple's own servers, suggests the company sold through whatever allocation it had ready for launch day at a brisk pace.
Whether that demand holds up is the open question heading into October 23. Apple has staked real engineering effort and manufacturing capacity on the idea that enough buyers want a bigger screen that folds into their pocket, even after Samsung spent the better part of a decade finding only a modest audience for the format globally. A strong debut would give Apple grounds to expand foldable production across more of its lineup in coming years; a soft one would leave the Duo as a niche, expensive outlier, more akin to the Vision Pro than to the iPhone's usual mass-market role.
What Happens Next
Reviewers will get hands-on units ahead of the October 23 launch, and early verdicts — including a first look from Engadget's Sam Rutherford, who called the Duo "Apple's most exciting device in a decade" despite the high price — will shape how the broader market responds. Carrier trade-in and financing offers, including Apple's own $83.29-a-month installment plan, are likely to do much of the work in making the $1,999 starting price more palatable to buyers accustomed to Apple's usual $999 flagship pricing.
