Good to know
Does Ultimate Custom Night work on iPhone Duo?
Not yet. Ultimate Custom Night's current version (1.0.6, April 9, 2025) came out before Apple's iPhone Duo tools, so on the inner screen it opens in an iPhone-size window with black bars. It works, just not full screen.
Why do some apps have black bars on iPhone Duo?
Because they were built before Apple's iPhone Duo tools. On the inner screen, an app built for an older iOS opens in an iPhone-size window on a black background; one built for iOS 27.0 uses more of it but leaves some space blank; only apps built with the iOS 27.1 SDK, which developers have had since October 5, 2026, use the whole display.
When will Ultimate Custom Night be adapted to iPhone Duo?
Only CLICKTEAM LLC USA knows. We check Ultimate Custom Night on the App Store again within about 1 h: this page changes as soon as a new version says it supports iPhone Duo.
Do apps that aren't adapted still work on iPhone Duo?
Yes. Every iPhone app runs on iPhone Duo: one that isn't adapted just doesn't fill the inner screen until its developer updates it.
How we measure
Sources: Apple's list of apps adapted to iPhone Duo (October 22, 2026) and each app's App Store record (version, release date, release notes, description). Apple doesn't say which tools an app was built with, so an app stays “Updated, unconfirmed” until its developer says more.
