Countdowns to big days, with notes and to-dos beside the event's photo when open
Does Memento: Days Countdown Widget work on iPhone Duo?
According to its developer, yes. FoldHunt's editor hasn't checked Memento: Days Countdown Widget on iPhone Duo yet, so it's listed as a claim.
- Developer claimedAnand Raj R, the developer, in a post on X saying Memento is now optimised for iPhone Duo, with screenshots of it closed and open (@arrcade_dev on X). The current App Store version (2.6, September 11, 2026) only mentions iOS 27 compatibility, not the Duo.

The countdown on the cover
Closed, the event's photo fills the cover with the time left and the date over it, and a player for the event's song if you picked one.
About Memento: Days Countdown Widget
Memento counts down the days to events you add, each with its own photo, and can play a song from Apple Music for the event. Anand Raj R has been updating it for 13 years, since the iPhone 4. On the Duo, the open screen puts the event’s notes and to-dos on one half and its photo on the other.
