Apple is giving a new twist to its flagship smartphone line: The company unveiled the iPhone Duo, its first foldable smartphone model.

The company’s iPhone Duo foldable has two screen panels that have the largest, most immersive screen size ever — as well as being its thinnest iPhone ever, according to Apple. The line includes the single-screen iPhone 18 baseline model and Pro and Pro Max versions.

The Apple launch Wednesday comes seven years to the day after Samsung shipped its first foldable smartphone, the Galaxy Fold, in September 2019.

The iPhone 18 and iPhone Duo is the first product launch event presided over by newly installed CEO John Ternus, formerly Apple’s head of hardware engineering, who took over from Tim Cook at the helm of the tech giant as of Sept. 1.

Other foldable designs feel like “two phones that have been stuck together,” Ternus said about the foldable phone.

The iPhone 18 is “your intelligent personal hub,” Ternus said in a video played at the top of the event He underscored that its Apple Intelligence AI features — including an enhanced Siri AI app that has more “expressive” voices — run locally on the device whenever possible to protect users’ data privacy.
