A reading tracker whose book details and stacks spread across two columns when open
Does Unshelved: Read. Stack. Track. work on iPhone Duo?
Yes, from launch day, says its developer: open, a book's cover sits beside your progress, rating and dates, and two stacks show side by side. Version 1.2.12 refined the upright layouts.
- App Store confirmedAbhilash Kuduvalli, the developer, in a submission to FoldHunt on October 22, 2026, and in a Bluesky post (@c0up.bsky.social) the same day saying Unshelved is iPhone Duo-ready, with a picture of the app on the cover and the open display. The App Store seller is Abhilash Kuduvalli. The release notes for version 1.2.12 (released October 23, 2026) mention improved portrait layouts on iPhone Duo, with a single stack in Library and a single-column Update Book screen, and onboarding improvements when it's unfolded.
Adapted for the fold
- Open · Inner display
Book details in two columns
Open, importing a book or updating your progress shows the book's cover on one side and your pages read, rating and start and finish dates on the other, and two stacks in your Library sit side by side. Turned upright, the Library keeps to one stack and Update Book to one column.
- Closed · Outer display
Your stack on the cover
Closed, the developer's picture shows the cover with your Library's stack of books and the pages you've read.
About Unshelved: Read. Stack. Track.
Unshelved is a reading tracker that shows your books as a stack in the app and on Home Screen widgets, rather than a grid of covers. You track the pages you read through the seasons, add books from photos or screenshots, and queue up what to read next.
On the iPhone Duo, says Abhilash Kuduvalli, importing a book or updating your progress opens into two columns, with the book’s cover beside your pages read, rating and dates, and if you keep two stacks, the open display shows both. Version 1.2.12, out on October 23, 2026, refines the Duo’s upright layouts, with one stack in Library and a single-column Update Book screen, and improves onboarding when the phone is unfolded.

Developer claimed · iphone-duo
Looked at the picture in the developer's Bluesky post: the app's screens placed on 3D-rendered iPhone Duo models, the closed cover with the Library's stack of books and pages read, and the open display, slightly bent, with a book's cover on the left and its progress, star rating and reading dates on the right. The screens carry the Duo status ring.
Poses shown: Closed, Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
The screens are composited on rendered phones, so the picture doesn't show the app running. The two stacks side by side and the upright layouts aren't shown, and no build was tested.
