Apple has officially introduced the iPhone Duo, its first foldable iPhone, ending years of speculation around the company’s entry into the foldable market. Apple says the phone is its thinnest iPhone ever when unfolded, with a design built around a new hinge that helps with both durability and how the phone feels in the hand. The foldable opens like a book and gives users a much larger screen for apps, videos and multitasking.

Apple has also focused heavily on the hinge, which plays a key role in the phone’s slim design and durability. The large inner display is 50% bigger than the iPhone 18 Pro Max’s screen, giving the Duo a more spacious setup when opened.

The iPhone Duo starts at $1,999, making it one of Apple’s most expensive iPhones. The top storage version is expected to reach around $3,000.
