Task steps on the cover, a two-page plan when open
Does InfiniteUp work on iPhone Duo?
Yes, the developer says so: InfiniteUp 1.0.57, released October 16, 2026, is laid out for iPhone Duo, and the maker shows web-app previews of the cover and open layouts.
- App Store confirmedThe developer, on its iPhone Duo page: the App Store version uses the full open display, and the release notes for version 1.0.57 (released October 16, 2026) say it is laid out for iPhone Duo. The page's six pictures are the web app captured at Duo sizes, not screenshots from the simulator or a device. Layouts for the half-folded Duo are still planned.
Adapted for the fold
- Closed · Outer display
Steps for the next task
In the maker's cover-size preview, Focus Mode stays in one column, with the current task broken into steps, and the Briefing has a compact newspaper layout.
- Open · Inner display
A two-page planning space
The open-size previews put task steps beside a progress path, split the board around the middle and spread the Briefing across two pages. The week shows four days, with a Future rail at the edge.
About InfiniteUp
InfiniteUp breaks tasks into smaller steps and combines a board, a week view and a daily Briefing. The maker has laid these screens out for the Duo’s cover and open display, leaving a gap through the middle of the wider views.
The pictures on the maker’s page are the web app captured at Duo sizes on October 15, not screenshots of the app running in the simulator; the maker reports trying an earlier build in the simulator. Half-folded layouts and a pass on a real device are still to come.

Looked at all six maker captures: task steps and the Briefing at cover size, and steps with progress, the board, a four-day week and the two-page Briefing at open size. The page says they are the web app captured at Duo sizes.
Poses shown: Closed, Open. These are observations of the evidence, not a test of every interaction.
App version: Not recorded in this evidence.
These are browser captures, not evidence from the Duo simulator or a device. No installed build or fold transition was tested. The App Store version at the time, 1.0.55, listed Duo optimization; half-folded layouts are still planned.

by InfiniteUp
InfiniteUp fits the Duo: task steps fill the cover, and open, they sit beside a progress path. The board and the daily Briefing also span two pages. These previews are captured in a browser, not the simulator.
