Health and fitness cards that spread into a wider grid on the open Duo
Does Peak work on iPhone Duo?
Yes: version 5.5 (October 22, 2026) says Peak is ready for iPhone Duo, and the developer's simulator recording shows the closed cards two across and a wider grid when open.
- Simulator verifiedThe developer, Harshil Shah (@harshil), in a post on X with a video of Peak on the iPhone Duo simulator, closed and open (@harshil on X). The App Store seller is Harshil Shah (id 6443923491).

Cards two across
Closed, the dashboard's cards sit two across, with the tabs in a strip down the side.

Open flat, the cards spread to three across, a workout's stats sit beside the list of workouts, and settings sit beside the icon picker instead of on top of it.
About Peak
Peak is Harshil Shah’s app of health and fitness cards and widgets. In the video, on the iPhone Duo simulator, the closed phone shows the dashboard’s cards two across with the tabs in a side strip. Opened flat, the cards spread to three across, a workout’s stats sit beside the list, the settings sit next to the icon picker, and the recaps get room to breathe.

Recorded on October 9, before version 5.5 (October 22), which says the dashboard shows up to four columns; no app or Xcode version is shown. It doesn't show the half-folded poses or Split View. No build was tested.
