Send a simulator build and it checks your app's everyday flows on iPhone Duo's cover and inner screens, flagging fixed-width layouts, letterboxing, controls stuck in the side column, and settings like UIRequiresFullScreen that block Duo support. It also checks dark mode, large-text rendering and unlabelled controls for VoiceOver, all graded against Apple's Human Interface Guidelines. It explicitly doesn't record the fold animation itself or tap the inner display — layout and continuity only.
What holds up
- +States exactly which compatibility mode your app ran in and what was tested
- +Checks dark mode, large-text and VoiceOver labels, not just the Duo layout
- +Reads Info.plist directly to catch orientation locks that block Duo support
Mind the limits
- −Doesn't test the fold animation itself or tap the inner display — layout checks only
- −No pricing shown — you request access and wait for a reply before seeing cost
