Short answer
For most apps, React Native costs less over three years than building separate native apps and performs the same to users. One codebase means each feature and bug fix is written once, and over-the-air updates skip app store review. Fully native is worth the added cost for AR, heavy real-time 3D or games, and deep hardware integration.
"React Native or native mobile app development?" is usually the wrong question, because it's framed as a quality contest React Native already settled for most apps years ago. The question that actually matters is a maintenance question: which approach costs less, in engineering hours, to keep two platforms (iOS and Android) in sync over the three years after launch, not just to ship version one.
That reframing matters because most of the React-Native-versus-native debate happens at the wrong moment, before a single line of either has been written, based on impressions rather than the specific shape of the app. Here's a more useful way to work through it.
Cross-platform mobile app development: where React Native matches native
For the large majority of apps (business tools, forms and data entry, content-driven apps, booking and scheduling, and even a lot of offline-heavy and location-aware apps), React Native performs indistinguishably from a fully native build to an end user. The parts people expect to break are now handled by mature libraries: background location, local databases for offline-first sync, push notifications, and camera access all have well-maintained React Native modules.
When React Native doesn't cover something, you write that one piece natively and keep the rest shared. Our LuxeHQ app for Luxe Miami is a working example: a React Native app live on iPhone and iPad, where uploads keep running in the background and resume after a dropped signal, and upload progress shows on the Lock Screen through an iOS Live Activity. The Live Activity is native iOS code. Everything else, from the video library to the share flow, is one cross-platform codebase that can ship to Android without a rewrite.
Key takeaway
Most apps need a few native modules, not a native app. Write those pieces in Swift or Kotlin and keep the rest of the codebase shared.
Where native mobile app development still wins
None of that means cross-platform is the right call unconditionally. There's a real, if shorter, list of cases where fully native is worth its added cost:
- Augmented reality or heavy real-time 3D rendering, where you're working directly against ARKit/ARCore or a game engine rather than a UI layer.
- Deep, low-level hardware integration, such as custom peripherals, sensor fusion, or camera pipelines beyond what a React Native module or Expo plugin exposes.
- Apps that need a brand-new OS-specific API on the day it ships, before a stable cross-platform bridge exists for it.
- Performance-critical games, where frame budget is the entire product experience, not one feature among many.
Key takeaway
If none of these describe your app, the cost of building and maintaining two native codebases is very hard to justify against one cross-platform codebase that performs the same to users.
React Native vs. native: the real three-year cost comparison
This is where the decision actually gets made, and it rarely gets made at launch. It gets made in the eighteen months after, when every feature has to ship twice.
| Cost driver | React Native | Fully native (Swift + Kotlin) |
|---|---|---|
| Initial build | One codebase, one team | Two parallel builds, typically close to double the engineering time |
| Feature parity over time | One change ships to both platforms at once | Two separate implementations that can drift apart release over release |
| Bug fixes | Written and tested once | Written twice. A fix landing on one platform but not the other is a common native-project failure mode |
| Hiring | One team of React/TypeScript engineers maintains both platforms | Needs a dedicated iOS engineer and a dedicated Android engineer, or one generalist context-switching between two ecosystems |
| Shipping a fix | Over-the-air updates (Expo/CodePush) ship without waiting on app store review | Every fix, however small, waits on the review queue |
App Store and Play Store approval realities
Whichever approach you build with, approval isn't instant, and first submissions get rejected more often than founders expect. Apple typically reviews within one to three days, Google within a few hours to a couple of days. But the rejection itself is the part that catches teams off guard.
- Incomplete or vague privacy disclosures, especially around location, contacts, or health data.
- Background location or notification permissions requested without a clear, user-facing justification in the review notes. This is a real issue for anything doing background GPS tracking, like a trail or fleet app.
- Broken login flows or demo accounts that don't work for the reviewer, which reads as an incomplete app rather than a minor bug.
- Metadata or screenshots that don't match the actual current build.
Key takeaway
Budget time for at least one resubmission round on any new app. Treating first-submission approval as the default plan is where launch timelines quietly slip.
If a previous app got stuck mid-build or abandoned
We inherit React Native codebases regularly, usually after another team stalled out or moved on. The first step is always a codebase audit before any new work starts. Sometimes the existing app is salvageable and extending it is faster than starting over. Other times the accumulated shortcuts make a clean rebuild the faster path. We'll tell you honestly which situation you're in before quoting anything, rather than defaulting to a rebuild because it's easier to scope.
If you're weighing this for a real product, or inherited one that's stalled, our mobile app development company team can review what you have and give you a straight recommendation on cross-platform versus native for your specific requirements. If cross-platform fits, here's how we approach React Native mobile app development.
