Cross-Platform Efficiency
One codebase, two stores, and platform code written only where the platform genuinely differs. Your team reviews one pull request instead of reconciling two, and a fix lands everywhere at once rather than twice, a fortnight apart. The shared layer is where the product logic lives; the native layer is where the phone's own conventions do. Keeping that line clean is most of the work, and it is the reason a change of direction in month nine costs a sprint instead of a rewrite.
