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

The company’s iPhone Duo foldable has an internal dual-display panel that provides the largest, most immersive screen size ever at 7.6 inches diagonally — and it’s also the thinnest iPhone ever, according to Apple. (When unfolded, it looks like a small iPad tablet.) There’s also a screen on the outside of the device.

The iPhone Duo is priced starting at $1,999 with 256 gigabytes of storage, ranging up to $3,199 for a model with 2 terabytes. Preorders start Oct. 16 and the device will begin shipping Oct. 23. It’s available in two colors, dubbed “star white” and “night sky.”

According to Apple, a few third-party apps — including Netflix, Zoom and Slack — are already taking advantage of folding display and the larger screen. Apple is releasing software development kits for developers to design (or redesign) their apps for the iPhone Duo.

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