An inkblot parlor game: drop ink inside, close the Duo to press it, open a mirrored blot
Does Inkblotter work on iPhone Duo?
Duo support is shown in the simulator and the app is out: closed, a notebook cover; open, ink pressed between the pages makes a mirrored blot. Version 1.0 is on the App Store.
- Simulator verifiedThe Peninsular Company, on its product page, showing Inkblotter in a 27-second recording from the iPhone Duo simulator: the notebook cover, ink placed on the right page, a mirrored blot after closing and reopening, and a reading on the right. The page announced version 1.0 for October 23, 2026. Version 1.0 is now on the App Store (seller Joseph Lint, released October 22, 2026), and its description says "Inkblotter turns iPhone Duo into the paper."

Inside, you place ink on the right page. Close the phone and reopen it, and the blot is mirrored across the two pages, followed by a reading on the right.
About Inkblotter
Inkblotter is a parlor game made for the iPhone Duo. Closed, it shows a notebook cover; open, you put ink on the right page, close the phone, and reopen it to find a symmetrical blot across the spread, with a reading on the right. The maker’s simulator recording shows the closed and open layouts, but not a separate half-folded pose.
The Peninsular Company announced version 1.0, for iPhone and iPad, for October 23, 2026. It is on the App Store now, listed under the seller Joseph Lint, with a release date of October 22, 2026.
The maker describes the readings as a parlor game, not a psychological assessment.

· Simulator recording reviewed
Simulator verified · iphone-duo
Looked at the maker's original 27.5-second film, which the maker labels a Duo simulator recording: the cover and inner views, drawing ink, closing and reopening, and the resulting mirrored blot with a reading on the right.
Poses shown: Closed, Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
An edited, silent simulator capture with no app or Xcode version visible. No bent device frame is shown, so only the closed and open poses are recorded. No build, physical hinge, haptics, audio or readings were tested, nor the app's privacy claims. The public release is announced for October 23, not confirmed.
