Does Hit the Button Maths work on iPhone Duo?
Not yet. The latest version of Hit the Button Maths we've seen on the App Store (1.2.5, released June 13, 2024) came out before Apple started accepting iOS 27.1 SDK builds on October 5, 2026, so it isn't built for the full iPhone Duo display. Depending on how it was built, it either fills most of the inner display or opens in a smaller window with empty space around it.
