Duo Themes / iPhone Duo
For iPhone Duo · FreeiPhone Duo wallpapers, widgets & themes
Two screens deserve one look. Design widgets, Lock Screen widgets, wallpapers and icons in a single palette — and carry it from the cover screen to the inner screen.
Free on the App Store. Requires iOS 17.0 or later.
Why theming a foldable is different
iPhone Duo opens from a phone-shaped cover screen into a much wider inner screen. A wallpaper cut for one rarely looks right on the other.
Two shapes
The tall cover screen and the near-square inner screen crop the same image in completely different places.
Exact resolution
Duo Themes renders every wallpaper at the pixel size of the screen it's open on, so nothing is stretched or soft.
One palette everywhere
Use the same palette for widgets, Lock Screen widgets, wallpaper and icons so both screens feel like one design.

iPhone Duo FAQ
Does Duo Themes work on iPhone Duo?
Yes. Since version 1.1, Duo Themes is made for iPhone Duo: it uses the whole inner screen, adds extra-large widgets, and can save any wallpaper as a set for both screens. Widgets, Lock Screen widgets and the icon studio work the same way they do on other iPhones.
What size wallpaper does iPhone Duo need?
iPhone Duo has two displays — a 5.4-inch cover screen and a 7.6-inch inner screen — with different shapes. Duo Themes saves a single wallpaper at the exact resolution of the screen the app is open on. For both screens at once, use an iPhone Duo set: one 4096 × 2048 image that iOS fits to each screen, or two images at each screen's exact size.
Can I use one wallpaper on both screens?
You can, but because the inner screen is much wider, the same image gets cropped very differently. That's why Duo Themes 1.1 adds iPhone Duo sets: the same style, palette and seed laid out for each screen, previewed side by side and saved in one tap.
How do I make an iPhone Duo set?
Open any wallpaper, tap iPhone Duo set, check the cover and inner previews, then save. It's free — if you already have Duo Themes, update to version 1.1 or later from the App Store.
Is Duo Themes made by Apple?
No. Duo Themes is an independent app and isn't affiliated with or endorsed by Apple. iPhone Duo is a trademark of Apple Inc.
