How iPhone Duo grades work
Each app is graded on how it handles the foldable: filling the 7.6-inch inner display, dual-pane layouts, drag and drop across the fold, and keeping its place when you fold or unfold. The grade out of 10 sums it up. Grades come from a hands-on test where there has been one, and otherwise from what Apple and the developer have announced; every app page says which.
