Live video where the whole room reacts at once: stars, gifts, and the sky itself
Does Lumecast: Live Streaming work on iPhone Duo?
Yes, since version 3.3.1 on October 17, 2026, and seen in the developer's screenshots of the open Duo: the cast fills the left page, and chat, gifts and guest seats fill the right.
- Simulator verifiedCurtis Tunaley, the developer, in a submission to FoldHunt on October 17, 2026, with screenshots of the open Duo on the Lumecast site (lumecast.app). The App Store seller is Curtis John Tunaley. The release notes for version 3.3.1 (released October 17, 2026) say the update is for iPhone Duo launch week: the camera follows you when you fold or unfold, the cast takes one page and the room the other, and half-folded it becomes a camcorder.
Adapted for the fold
- Open · Inner display
The cast on one page, the room on the other
Open, the cast takes the left page at full size with nothing drawn over it. Chat, the gift sheet, guest requests and the top-gifter podium take the right page. Stars and sky gifts are the one thing allowed to cross the fold, so a gift fills both pages at once.
- Book · Partly folded
A camcorder on the table
Half-folded on a table, the video sits on the upright half and the controls on the flat half, like a camcorder. Fold or unfold while live and the app switches to the camera that now faces you, so your face stays in view.
- Closed · Outer display
A live card on the cover
Closed, the cover shows the familiar phone layout and a glanceable live card, and the cast never reconnects.
About Lumecast: Live Streaming
Lumecast is live video for small rooms. Go live from your phone, let your orbit in, and light up the room with stars and gifts. Viewers chat in real time, send stars that sparkle across everyone’s screen, and thank creators with gifts. It’s free on iPhone and Android, for ages 17 and up.
Version 3.3.1, out on October 17, 2026, was made for iPhone Duo launch week. Open, the cast takes the left page at full size and the room takes the right: chat, the gift sheet, guest requests and the top-gifter podium get their own space instead of hiding the video. A gift is the whole room’s moment, so stars and sky gifts cross the fold. Half-folded on a table, the app becomes a camcorder, and folded shut, the cover shows the phone layout you already know. The developer’s site has screenshots of the app on the open Duo.

Looked at the unframed iPhone Duo screenshots in the site's Duo section. They show the app on the open display with the Duo's own status clock: the host's front and rear cameras fill the left page while chat and the top-gifter badge fill the right; a Flame gift bursting across both pages at once; and the Watch tab spreading live casts across the wide display.
Poses shown: Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence. Environment: iPhone Duo simulator or device, not stated by the developer.
The site doesn't say whether the screenshots come from the simulator or a device, and gives no app or Xcode version. The pictures are scaled down, but their shape matches the simulator's open display. The half-folded camcorder layout and the cover aren't shown, and a fourth picture of a stacked layout, cast above and chat below, isn't clearly one pose. No build was tested.
