For most business apps, React Native is the better choice: one team builds iOS and Android from a single codebase, the result uses real native interface components, and users rarely notice any difference from a fully native app. Native development in Swift and Kotlin wins when the app’s core value depends on heavy graphics, augmented reality, advanced audio or video processing, deep integration with the newest operating system features, or when you already have strong separate iOS and Android teams.
That’s the short answer to React Native vs native. The rest of this guide explains the trade-offs in plain terms so you can make the call for your app, and avoid the less obvious costs on both sides.
What is the difference between React Native and native apps?
A native app is built separately for each platform with the platform’s own tools: Swift and SwiftUI (or UIKit) in Xcode for iOS, Kotlin and Jetpack Compose in Android Studio for Android. Two codebases, usually two teams, full access to everything the platform offers.
A React Native app is written mainly in JavaScript or TypeScript using React, the same model many web teams already know. It doesn’t run inside a web page. It drives real native interface components, so a button is an iOS button on an iPhone and an Android button on a Pixel. Platform-specific pieces can be written in Swift or Kotlin and called from the shared code.
Most teams today build React Native apps with Expo, a framework and set of services around React Native that handles builds, native configuration, over-the-air updates and store submission. It removes much of the set-up work that used to make React Native projects fiddly.
There are other cross-platform options, notably Flutter (Dart, with its own rendering engine) and Kotlin Multiplatform (shared Kotlin logic with native or shared interfaces). They’re credible choices; this article focuses on React Native because it’s the most common cross-platform choice for teams that also build for the web in TypeScript.
React Native vs native at a glance
| Criterion | React Native | Native (Swift and Kotlin) |
|---|---|---|
| Codebases | One shared codebase, some platform-specific code | Two separate codebases |
| Team | One team, TypeScript and React skills, some native skills | iOS and Android specialists |
| Time to first release on both platforms | Shorter | Longer, unless both teams work in parallel |
| Interface | Real native components; platform look by default | Real native components, every platform detail available |
| Everyday performance | Indistinguishable for typical business apps | Excellent |
| Graphics, AR, heavy media | Possible, but often needs native modules | Best choice |
| New OS features on launch day | Often available after a delay, or via a native module | Immediately |
| Code sharing with your web app | High: types, validation, API clients, business logic | Low |
| Over-the-air fixes | JavaScript updates can ship without a store release, within store rules | Every change goes through store review |
| Long-term maintenance | One upgrade path plus native dependencies | Two upgrade paths |
When does React Native win?
React Native is the pragmatic choice when:
- The app is mostly screens, forms, lists and data. Field inspections, work orders, approvals, ordering, customer self-service, employee apps and dashboards fit perfectly.
- You need both iOS and Android, with the same features. Most B2B apps must support both, because staff and customers bring both kinds of phone.
- Your team, or your vendor, is strong in TypeScript and React. You can share types, validation rules and API clients with your web app and keep behaviour consistent.
- Time to market matters. One team shipping one codebase reaches both stores sooner.
- You want to fix issues quickly. Over-the-air updates for JavaScript changes let you correct a bug without waiting for a full store review, as long as the update doesn’t change the app’s purpose and stays within Apple’s and Google’s rules.
Large companies run major apps on React Native, so it’s a mainstream, well-supported choice rather than a shortcut.
When does native win?
Choose native development when:
- Graphics or media are the product. 3D, augmented reality with ARKit or ARCore, real-time video effects, advanced camera pipelines, games or audio production.
- You depend on new OS features from day one. Widgets, Live Activities, Apple Watch and Wear OS companions, CarPlay and Android Auto, and new system integrations arrive first in the native toolkits.
- Heavy, continuous hardware work. Apps that stream large amounts of Bluetooth sensor data, run on-device machine learning constantly, or manage complex background processing benefit from going native, though React Native can still handle many of these through native modules.
- You already have strong native teams. If you employ experienced iOS and Android developers, switching stacks costs more than it saves.
- Every millisecond and megabyte matters. Native apps can be smaller and start a little faster, which matters for some consumer apps at very large scale.
Is React Native fast enough?
For business apps, yes. React Native’s historic weakness was the “bridge,” which passed messages between JavaScript and native code asynchronously. The New Architecture replaced it with direct communication between JavaScript and native code (through JSI), a new rendering system and on-demand loading of native modules. It became the default in React Native 0.76 in late 2024, and from version 0.82 in October 2025 it’s the only architecture.
In practice, performance problems in React Native apps today usually come from the same causes as in any app: long lists rendered inefficiently, too much work on the main thread, oversized images and chatty network calls. A competent team avoids them in either stack.
What does each cost to build and maintain?
React Native usually costs less to build because one team writes most of the code once. How much less depends on how much of the app is shared. For a typical business app, the shared portion is high; for an app full of platform-specific features, the savings shrink.
Maintenance is where people underestimate both options. Apple and Google raise their requirements every year:
- Apple: since April 28, 2026, apps uploaded to App Store Connect must be built with Xcode 26 or later using the iOS 26 SDK.
- Google Play: from August 31, 2026, new apps and app updates must target Android 16 (API level 36), with an extension available to November 1, 2026.
A native app needs two sets of updates. A React Native app needs framework upgrades plus updates to its native dependencies. Either way, budget for an annual upgrade cycle, security patches and testing on new OS versions. An app that isn’t maintained eventually can’t be updated in the stores at all.
Common mistakes on both sides
- Choosing React Native with no native skills on the team. Sooner or later you’ll need a native module or have to debug a build. Have someone who can.
- Choosing native for a simple data app. Two teams building the same forms twice is expensive and leads to features drifting apart between platforms.
- Ignoring offline use. Field apps must work in basements, rural sites and warehouses. Design the offline data and sync strategy first, whatever the stack.
- Skipping the back end. The app is often the easy part. Authentication, APIs, integration with your ERP or CRM and push notification infrastructure carry the real complexity.
- No release process. Automated builds, test distribution through TestFlight and Play testing tracks, crash reporting and staged rollouts should be in place before launch.
How to decide
Ask five questions:
- Is the core of the app data, forms and workflows, or graphics, media and hardware?
- Do you need iOS and Android with the same features?
- What does your team, or your vendor, actually know well?
- Will the app share logic with a web app or customer portal?
- Which brand-new OS features must you support on launch day?
Data and workflows, both platforms, TypeScript skills and shared logic point to React Native. Heavy graphics, day-one OS features and existing native teams point to native.

How we build mobile apps
Our iOS and Android app development team builds most business apps in React Native with Expo, and writes native Swift and Kotlin when the app calls for it. We design the back end, offline sync and integrations with your systems alongside the app, through our systems integration and cloud and DevOps work, and we stay on to handle the yearly store and OS updates.
