In short: for the vast majority of business applications, marketplaces and startup products, a cross-platform technology is the right choice in 2026. React Native is the most consistent option if your team or your web product already uses React and TypeScript. Flutter is very solid for heavily customised interfaces. Native (Swift and Kotlin) remains justified for applications that make deep use of the hardware or whose graphics performance is the core of the product.
The choice of technology is rarely what makes an application succeed or fail. But it shapes the budget, the delivery speed and the ease of hiring for several years. Here is how to decide.
The three approaches in one sentence
- Native: two separate applications, one in Swift for iOS, the other in Kotlin for Android, with the official tools from Apple and Google.
- React Native: a single codebase in TypeScript and React, which drives real native components on each platform.
- Flutter: a single codebase in Dart, with its own rendering engine that draws the interface identically on iOS and Android.
The comparison
| Criterion | Native (Swift / Kotlin) | React Native | Flutter |
|---|---|---|---|
| Code shared between iOS and Android | None | Very high | Very high |
| Development cost | The highest (two teams) | Reduced | Reduced |
| Performance | The benchmark | Very close to native | Very close to native |
| Interface rendering | Native components | Native components | Own rendering engine |
| Language | Swift and Kotlin | TypeScript | Dart |
| Code sharing with the web | No | Yes (logic, types, sometimes components) | Limited |
| Developer pool | Specialised | Very large (React ecosystem) | Growing |
| Access to new iOS and Android features | Immediate | Fast, sometimes via a native module | Fast, sometimes via a native module |
| Updates without going through the stores | No | Yes for the JavaScript code | More limited |
React Native: the default choice when you already work with React
React Native has changed a lot. Its new architecture, now enabled by default, removed the old communication bridge that accounted for most of the performance criticism. With Expo, setting up, building and publishing an application have become markedly simpler than a few years ago.
Its strengths:
- A single language from web to mobile. If your website or SaaS is built in React or Next.js, the same team can work on mobile, sharing business logic, types and API calls.
- A huge hiring pool. React developers are the most numerous on the front-end market.
- Real native components. The application behaves like an iOS application on iOS and like an Android application on Android.
- Fast updates. Fixes to the JavaScript code can be deployed without waiting for store review, in compliance with their rules.
Its limits: features very close to the hardware sometimes require writing a native module, and the quality of third-party libraries is uneven. You need a team that knows how to choose them.
It is the technology we use at Inprogress for our mobile applications, precisely because our teams work in React and TypeScript across the whole product.
Flutter: visual consistency above all
Flutter draws every pixel itself. The result: a strictly identical interface on all platforms, and great freedom for highly customised designs and complex animations.
Its strengths:
- Identical rendering everywhere, with no surprises between iOS and Android.
- Excellent graphics performance for rich interfaces.
- Consistent tooling, provided by Google, with few dependencies to assemble.
Its limits: Dart is a language that is little used outside Flutter, which narrows hiring and prevents pooling resources with a web team. And since the interface doesn't use native components, it can feel slightly different from the conventions of each platform if the team doesn't pay attention to it.
Native: when the platform is the product
Native development remains the benchmark in specific cases:
- games and applications that are graphics-intensive or compute-intensive
- advanced use of the hardware: augmented reality, real-time video or audio processing, complex Bluetooth
- deep integration with the system: elaborate widgets, smartwatches, CarPlay, extensions
- the need to adopt new Apple or Google APIs as soon as they are released
The price to pay is well known: two codebases, two teams, and every feature developed twice. For a management, content or commerce application, this extra cost buys nothing the user can perceive.
The decision rule
- Does your application rely on an advanced hardware or graphics capability? If so, native.
- Do you already have a web product or a team working in React and TypeScript? If so, React Native.
- Is your interface highly customised, with a team ready to adopt Dart? Flutter is an excellent choice.
- None of these cases applies? Choose the technology your team or your agency masters best. At this stage, the team's skill matters more than the framework.
What about progressive web apps?
A PWA, meaning a website that can be installed on the home screen, is sometimes enough: an internal tool, a service consulted occasionally, a very tight budget. It avoids the stores and their commissions. In return, access to the phone's features remains more limited, especially on iOS, and visibility on the App Store and Google Play is lost. It is a good first step, rarely a final destination for a consumer product.
Can you change technology later?
Yes, but it is a rewrite, not a migration. The back end, the design and the product knowledge are kept; the application code is not. That is why the choice deserves real thought at the outset, without justifying weeks of hesitation: a well-built cross-platform application can live for many years.
Frequently asked questions
Is React Native as fast as native?
For business, content, commerce or messaging applications, the difference is imperceptible to the user. Native keeps an edge for games, real-time video processing and intensive use of the hardware.
What is the difference between React Native and Flutter?
React Native uses TypeScript and displays the native components of each platform. Flutter uses Dart and draws the interface with its own rendering engine. React Native integrates better with a React web ecosystem; Flutter guarantees strictly identical rendering everywhere.
How much do you save with a cross-platform technology?
Generally 30 to 40% of the development budget compared with two native applications, and even more on maintenance, since each change is developed only once.
Which major applications use React Native?
React Native is developed by Meta and used in several of its applications. Companies such as Microsoft, Shopify and Discord also use it in production.
Should you choose Expo for a React Native project?
In most cases, yes. Expo is now the approach recommended by the React Native team itself: it simplifies configuration, builds and updates, without preventing you from adding native code when necessary.
