CalendarF1's race calendar and live timing, with races and standings side by side open
Does Race Calendar & Live Timing work on iPhone Duo?
Yes, since version 1.6.0 on October 16, 2026, says its developer: open, the race list sits beside the race, both standings share a screen, and live timing becomes a pit wall.
- App Store confirmedKrzysztof Hendzel, the developer, in a submission to FoldHunt on October 19, 2026. The release notes for version 1.6.0 (released October 16, 2026) say the app is ready for iPhone Duo and fills both displays, and the CalendarF1 site and a post on X show the open layouts on a rendered, half-open Duo.
Adapted for the fold
- Open · Inner display
A pit wall when you unfold
Open, the race list sits beside the race you picked, and the driver and constructor standings share one screen. Live timing becomes a pit wall: the timing tower beside a second panel, with separate gap and lap columns, and drivers compared side by side. Panels split at the hinge.
- Closed · Outer display
The whole app on the cover
Closed, you get the full app, with the race calendar and live timing, as on any iPhone. Folding or unfolding keeps the open race and the live session.
About Race Calendar & Live Timing
Race Calendar & Live Timing puts every session of the racing season in your own time zone, practice, qualifying, sprint and race, or in the time at the track with one tap. It reminds you before sessions and when one moves, shows results and standings, and has live timing during sessions: positions, gaps, sectors, tyres, strategy, race control and weather, with replays back to 2023 and a spoiler-free mode. On an iPhone not set to Polish it runs as CalendarF1. It’s an independent app, not affiliated with Formula 1 or the FIA.
From version 1.6.0, out on October 16, 2026, the app fills both displays of the iPhone Duo, Krzysztof Hendzel says. Unfolded, the race list and the selected race sit side by side, so do the two championships, and live timing turns into a pit wall with separate gap and lap columns. Folding or unfolding keeps the race or live session you had open. The same wide layouts work on iPad.
