A habit and activity timer with a layout for every Duo pose
Does timespent work on iPhone Duo?
Yes, from launch day, says its developer. Cal told FoldHunt timespent is ready for iPhone Duo, and its site shows it open, half-folded, standing and on the cover.
- Developer claimedCal, the developer, in an email to FoldHunt on October 8, 2026, and on timespent's iPhone Duo page (timespent.so), which shows it in five poses. The App Store notes for version 3.5.1 say "let's get ready for iphone duooo".
Adapted for the fold
- Open · Inner display
Activities across the open Duo
Open in landscape, the Activities screen lays your cards across both halves: start and add buttons, a tutorial video, a photo, a streak calendar and the week's chart, with the controls in a column down the right edge.
- Open · Inner display
Four charts, upright
Turned upright, Supertrends shows four charts in a two-by-two grid, with the tab bar along the bottom.
- Book · Partly folded
The timer above its buttons
Half-folded like a small laptop, the timer fills the upright half, and reset, play and Done sit on the half lying flat, under a quote.
- Standing · Hands-free
A timer that stands on its own
Stood up on its side, the cover shows a full-screen timer in the activity's colour, with reset, play and Done.
- Closed · Outer display
Widgets on the cover
Closed, timespent's widgets fill the cover's Home Screen: a ring chart, today's minutes, a streak calendar and this month against the last.
