A TV show tracker whose cards step off the crease when the Duo half-folds
Does Countdown2Binge work on iPhone Duo?
Yes, and seen in simulator videos: version 3.0.5 (October 16, 2026) says it is optimized for the iPhone Duo, and Craig Clayton's YouTube series shows the adaptation.

Off the crease
Half-folded, a settings card that would sit across the crease moves onto one half, and it slides back to the middle when the phone opens flat.
About Countdown2Binge
Countdown2Binge counts down to the next season of the shows you follow. Craig Clayton adapted it for the iPhone Duo in a video series. In Episode 2, on the simulator, the notification settings card moves off the crease onto one half when the phone is half-folded and returns to the middle when it opens flat. Episode 1 moves the toolbar buttons into the side strip. Version 3.0.5’s release notes say the app now fits both Duo displays.
