A painting app where closing the Duo presses a mirrored print, like folded paper
Does Paint & Fold work on iPhone Duo?
Yes, and seen in the simulator: the developer's recording shows you painting on the open Duo, closing it to press, then opening it on a mirrored print.
- Simulator verifiedJames Davie, the developer, in a 37-second recording of the app in the iPhone Duo simulator on the app's site: painting on the open display, the press on the cover, and the mirrored print when the phone opens. Version 1.1 was released October 15, 2026.
Adapted for the fold
- Open · Inner display
Paint, then find the print
Open flat, the canvas runs across the fold, with colours and brush sizes along the bottom. Close the phone, open it again, and the paint has spread and printed in mirror image onto the other half.
- Closed · Outer display
Close the phone to press
Closed, the cover shows the painting blurred behind a Pressing message, then Ready to open.
About Paint & Fold
Paint & Fold is James Davie’s take on folding paper over a blob of wet paint and opening it on a butterfly. In the developer’s recording from the iPhone Duo simulator, you dab blobs and trails of paint on one half of the open canvas, then close the phone: the fold is the press, and the cover tells you when it’s ready. Open it again and a textured, mirrored print runs across the crease.
You can paint over a print and fold again to build up layers, then save or share the picture. On other iPhones, a Print button does the pressing.

· Simulator recording reviewed
Simulator verified · iphone-duo
Watched the developer's 37-second recording from the simulator: a pointer paints on the open canvas, the phone closes to a cover reading Pressing and then Ready to open, and opens again on a spread, mirrored print. Also looked at the site's three stills.
Poses shown: Open, Closed. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
No app version is shown and no build was tested. The recording shows the phone open and closed; the folding in between is an animation, not a half-folded layout.
