Every mobile project starts with the same argument: native for performance, cross-platform for speed. Both are right, and both are wrong, depending on what the product actually needs.
Start from the product, not the platform
If your app is a camera-heavy, offline-first tool with tight hardware integration, native is the honest choice — the platform APIs are simply better there. If it is a content and transaction app that must ship on two stores at once, a mature cross-platform stack will get you to market faster with a single codebase.
Count the team, not just the code
The real cost of native is two teams or one team context-switching. The real cost of cross-platform is the long tail: the feature that needs a platform plugin, the performance edge case, the store review that rejects the build. Budget for both, not just the happy path.
The decision we use
Three questions settle most cases: How hardware-close is the app? How fast must it ship on both stores? How big is the team that will maintain it for two years? Answer them honestly and the platform choice usually writes itself.
