## What is DuoWallpaper?

Fold Wallpaper — not just a wallpaper library, but an AI wallpaper studio: type an idea or upload any image you like, and AI turns it into your own wallpaper, up to 4K. Built for the iPhone Duo foldable — portrait wallpaper for the outer display, landscape for the inner display, applied as a matched set in one tap. Also great on any iPhone or iPad.

【AI-Generated Wallpapers】
· Describe an idea in one sentence, pick a ratio and quality, and AI generates your wallpaper in up to 4K
· Image-to-image: upload any picture you like and AI reimagines it as your own foldable wallpaper
