Sleep stories and sounds, with a bedside clock in a tent and a mixing desk half-folded
Does Sleepiest Meditation for Sleep work on iPhone Duo?
Yes, since version 17.63 on October 19, 2026, says its developer: stood in a tent it becomes a dimmed bedside clock, and half-folded its sound mixer becomes a mixing desk.
- App Store confirmedJenna Clarke, from the team behind Sleepiest, in an email to FoldHunt on October 20, 2026, and in a press release that day saying the free update is available from October 23, the day iPhone Duo goes on sale. The press pack's pictures of the Duo are device renders. The App Store seller is Happiest LTD. The release notes for version 17.63 (released October 19, 2026) describe the Duo features: a bedside mode in a tent, the play screen and a mixing desk split across the half-fold, and wider layouts open flat.
Adapted for the fold
- Standing · Hands-free
Bedtime mode on the bedside table
Fold the Duo into a tent and stand it on your bedside table, and Sleepiest becomes a dimmed night clock with just the time, your alarm, play and pause and the sleep timer, so you don't have to pick the phone up.
- Book · Partly folded
A mixing desk across the fold
Half-folded like a laptop, the sound mixer becomes a DJ-style desk: you pick sounds on the top half, and the bottom half holds a volume slider for each layer, a master volume and play and pause. The play screen splits the same way, with the artwork and story details above the fold and the controls below.
- Open · Inner display
Wider layouts, open flat
Open flat, Sleepiest spreads across the big display with wider layouts, and its close and back buttons move into the Duo's side bar, out of the way of what you're reading or watching.

Its iPhone Duo update is built around how the phone is used at night. Fold it into a tent on your bedside table and Sleepiest becomes a dimmed bedtime clock with just the time, your alarm, play and pause and the sleep timer. Half-fold it like a laptop and the sound mixer turns into a mixing desk, with sounds to pick on the top half and a slider for each layer on the bottom; the play screen splits the same way, with the artwork above and the controls below. Open flat, the layouts widen across the big display.

Developer claimed · iphone-duo
Looked at the twelve images in the press pack: seven device renders and five marketing images made from them. In a tent, bedtime mode shows a large clock, the story playing with sleep-timer and pause buttons, and a morning alarm. Half-folded like a laptop, the sound grid fills the upright half and five sliders and a master volume sit on the lower half. Closed, the cover shows the home, stories, meditations and energy screens.
Poses shown: Standing, Book, Closed. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
The pictures are renders on a 3D iPhone Duo model, not captures from the simulator or a device, and no app version is shown. No build was tested, so the dimming, the switch between poses and the open-flat layout are unchecked.
