It might take that long if you’re doing extensive UI theming and lots of custom widgets, but relatively few apps actually need those things. Even accounting for branding, a solid color scheme paired with Material Design on Android and UIKit on iOS are mode than good enough for the vast majority of cases. Creating garden variety CRUD apps with pleasant UX doesn’t actually take that long; it’s doing backflips and cartwheels with design that’s time consuming.
