Adapted for the fold
- Book · Partly folded
Two pages, nothing on the crease
Opened like a book, Now Playing sits on the left page and your sound tiles on the right, split at the fold, and nothing moves as it bends.
- Book · Partly folded
A sound machine on the nightstand
Set down half folded, the artwork and title sit on the upright half, and two rows of tiles and the playback bar on the flat half, right where your hand is.
- Closed · Outer display
The full app, closed
Closed, Now Playing is up front with the Sound Mixer, sleep timer and AirPlay under the volume; sideways it goes to two columns.
- Split View · Two apps
Phone layout in Split View
In half the screen Blankie takes the iPhone layout, and goes back to two pages when you drag the divider away. Folding never interrupts playback.
About Blankie
Blankie is a sound mixer for sleep and focus by Cody Bromley, inspired by Blanket for Linux. Mix rain, waves, wind, a fireplace and several kinds of noise, save presets, set a sleep timer and play through AirPlay; it levels imported sounds so nothing gets lost in the mix. It’s on iPhone, iPad and Mac and works with Siri, Shortcuts and CarPlay.
Version 2.1 supports iPhone Duo in every pose. Open like a book, Now Playing fills one page and your sounds the other, split at the fold; half folded on a nightstand, what’s playing stands on the upright half with your sounds in reach on the flat half. The developer’s captures from the simulator show these and the cover.

Checked the captures in Blankie's Duo guide, in the simulator's device frame with the 9:41 status ring: the cover with Rainy Window playing and the Sound Mixer button; the phone open like a book, Golden Hour on the left page and the Waves, Gentle Guitar and Wind tiles on the right; and seated, Fireside on the upright half with three tiles and the playback bar on the flat half.
Poses shown: Closed, Book. These are observations of the evidence, not a test of every interaction.
App version: 2.1.0. Environment: iPhone Duo simulator.
Still captures with no Xcode version; we didn't look at the guide's tent, upright and flat captures. No build was tested.
