Apple showed its newest iPhones on Wednesday.

One of them is a foldable model called Duo.

The new CEO, John Ternus, presented the lineup at Apple's Cupertino, California headquarters.

He took over from Tim Cook on Sept. 1.

Before he showed the Duo, Ternus said "actually there is one more thing."

This echoed the phrase used by Apple's late founder, Steve Jobs.

Ternus said the Duo has the largest display ever on an iPhone.

But it still fits in a pocket.

It opens to a 7.6-inch display, which is 80% larger than the newest iPhone 18 Pro.

Users can also use an Apple Pencil with it.

This feature was previously limited to iPads.

The Duo lets people split the screen between two apps.

They can also split it between two windows of the same website.

At $1,999, it is the most expensive iPhone yet.

Analyst Ben Wood of CCS Insight said the Duo was always going to eclipse Apple's other announcements.

He said it marks Apple's entry into the niche foldable category.

This category still accounts for less than 5% of the smartphone market.

The iPhone 18 Pro and 18 Pro Max start at $1,199 and $1,299.

Preorders begin Sept. 12, phones arrive Sept. 18, and the Duo comes Oct. 23.

The new models offer longer battery life, faster charging, and camera improvements.

These include "smart focus tracking."

Apple is also emphasizing Siri's new AI features and privacy.

Analyst Dipanjan Chatterjee of Forrester said the foldable launch follows Apple's playbook of waiting before entering a category.

He said Ternus must sustain Apple's momentum.

He must also prepare for a future when smartphones may no longer be consumers' main link to the world.
