Does DaysUp · Count Anything work on iPhone Duo?
Yes, since version 1.3.1 on October 20, 2026, says its developer: half-fold the Duo and your trackers spread across both halves, with Today on the left and nothing on the fold.
- App Store confirmedRyan Calpin of Calpin Labs, the developer, in a submission to FoldHunt on October 19, 2026. The release notes for version 1.3.1 (released October 20, 2026) say DaysUp is made for iPhone Duo: half-fold it and your trackers spread across both screens, with Today on the left and the Pro purchase buttons off the fold.

About DaysUp · Count Anything
DaysUp counts up from any moment and shows how much time has passed, live to the second: days together, a new job or home, a pet’s age, a habit, or “since I last ate out”. The big number is days; tap in for years, months, hours, minutes and seconds. Each tracker can have its own icon, style and colors, or a card designed by AI from a feeling you describe, and the design follows it to widgets, Live Activities, the Dynamic Island and StandBy. Milestones and goals are optional, and there are no ads.
Version 1.3.1, out on October 20, 2026, is made for the iPhone Duo. Half-fold it and your trackers spread across both halves, with the Today card on the left, Ryan Calpin says; open flat, the grid widens, and nothing important sits on the fold.
