# Quick summary Apple introduced the iPhone Duo at its September event in Cupertino. The Duo is a foldable iPhone that closes to a passport‑sized device and unfolds to a tablet‑like screen. It starts at $1,999, goes on sale October 23, and pairs Pro‑level internals with a form factor Apple hasn't used before.
# What Apple built The Duo aims to give you two usable screens in one device. When closed you get a 5.4‑inch front display for everyday phone tasks. Opened, the Duo reveals a 7.6‑inch inner display—the largest ever on an iPhone—which Apple positions as useful for media, multitasking, and productivity. Apple added a nano‑texture layer to reduce glare and quoted a peak brightness of 3,000 nits for both screens.
The chassis uses a titanium frame to keep the unfolded phone thin and relatively light. The shape is closer to a notepad than the tall, narrow foldables that force awkward thumb reach. Apple says the hinge and manufacturing improvements make the crease much less noticeable than earlier foldables.
