Apple has officially entered the foldable smartphone arena with the debut of the Duo, a high-end device priced at $1,999 that represents the technology giant's most significant design overhaul in nearly a decade. Unveiled during a presentation at Apple Park in Cupertino, California, the device introduces a brand-new form factor to the company's product lineup as it seeks to redefine mobile productivity.
Featuring rounded corners and physical proportions intentionally designed to mirror a standard passport, the Duo is built around an expansive 7.6-inch (19-centimeter) horizontal interior display. The screen is engineered to transition smoothly to a vertical orientation depending on user needs, while an external single display provides full access when closed. Apple noted that when unfolded, the Duo stands as the thinnest smartphone the company has ever engineered.
To achieve this ultra-thin profile while maintaining structural strength, Apple built the Duo using a new titanium body paired with a custom-designed hinge mechanism. The interior architecture relies on dual displays with a consistent aspect ratio, a structural decision aimed at replicating the familiar feel and versatility of an iPad while retaining the pocket-sized convenience of a standard phone.
The unveiling event at the Steve Jobs Theater marked the first major hardware showcase led by John Ternus in his role as Apple's new chief executive officer. Appearing alongside vice president of industrial design Molly Anderson, Ternus used the high-profile platform to outline his product vision and usher in a new hardware era for the California-based company.
Industry analysts consider the introduction of the Duo to be Apple’s most radical hardware evolution since 2017, when the company permanently removed the physical home button from the iPhone X. Maintaining consumer enthusiasm through major hardware revisions remains critical for Apple's broader business, given that the iPhone division generated $209.6 billion during its most recent fiscal year, representing just over half of the company's total annual sales.
Rather than framing the device solely as a luxury accessory, Apple is actively marketing the Duo as an advanced business and productivity tool for professionals. The larger internal screen real estate has been engineered to run multiple active application windows at the same time, bringing a multitasking capability to the handset that Apple previously developed for select iPad models.
During on-stage product demonstrations, Apple showed how the device’s wider screen area enhances business workflows, highlighting its ability to host multi-participant Zoom video conferences while simultaneously presenting an expanded view of the Slack messaging platform. The company emphasized that managing separate work tasks side by side offers tangible daily efficiencies that conventional single-screen smartphones cannot match.
In his keynote remarks, Ternus contrasted the Duo with competing folding phones already available on the market, criticizing earlier industry efforts as awkward and poorly suited for standard tasks such as vertical scrolling or video viewing. Ternus argued that the Duo overcomes these shortcomings by combining a pocketable form factor with tablet-grade performance, noting that the passport-style dimensions ensure the device feels familiar in the hand and easy to operate with one hand.
In addition to physical innovations, Apple positioned the Duo and its broader device ecosystem as a secure, personal artificial intelligence hub. Addressing widespread consumer concerns regarding data collection, Ternus stressed that Apple prioritizes user privacy over external data aggregation, remarking that user trust quickly erodes when individuals lose ownership and direct oversight of their personal information.
Under this privacy-focused framework, Apple confirmed that its Apple Intelligence features will execute computing tasks directly on the device whenever feasible. This architecture is central to the newly enhanced capabilities built into Siri, with Apple seeking to leverage on-device privacy and security to differentiate its AI offerings from market competitors who rely more heavily on remote server processing.
Alongside the foldable flagship, Apple also introduced its standard next-generation devices, the iPhone 18 Pro and iPhone 18 Pro Max. These traditional models, which carry starting price tags of $1,199 and $1,299 respectively, incorporate targeted internal improvements to overall performance, camera capabilities, and battery life.
The company will employ a staggered release schedule for its new smartphone portfolio. Preorders for both the iPhone 18 Pro and iPhone 18 Pro Max will begin on September 12, with official retail availability following on September 18. Customers seeking to purchase the $1,999 Duo will have to wait several weeks longer, as the foldable model is scheduled to arrive on October 23.
Apple’s venture into the foldable category comes years after key market rivals, including Samsung, Google, and Motorola, introduced their own folding devices. Historically, Apple has avoided rushing early onto unproven hardware trends, choosing instead to let initial manufacturing and usability challenges play out before delivering its own refined interpretation of the technology.
This deliberate timeline was highlighted by Forrester analyst Dipanjan Chatterjee, who remarked that the Duo release matches Apple’s established strategy of waiting for early technical kinks to be resolved and market viability to be demonstrated before entering to shape the category. However, Chatterjee pointed out that foldables still make up only a tiny fraction of total smartphone sales, meaning the ultimate test for Apple will be whether it can expand a niche market into a truly meaningful industry segment.
