The Duo could shake up a category long dominated by Samsung and Chinese companies like Huawei. Analysts have long said Apple's entry could be the catalyst foldables need, helping bring the form factor into the mainstream much as the company did with smartwatches and wireless earbuds.
The Duo is sized and shaped like a passport, with rounded edges. It opens into a horizontal, 7.6-inch-diagonal (19 cm) screen that also can be viewed vertically. There is a smaller single screen on the front, when the phone is folded.
The iPhone Duo will be available from October 23.
Executives also showed off the iPhone 18 Pro and the 18 Pro Max handsets that are the latest versions of Apple's well-known line, which do not fold. Pricing for the iPhone 18 Pro and Pro Max starts at 1,199 USD and 1,299 USD, up 100 USD from the starting prices of the iPhone 17 Pro and Pro Max.
