When a company decides to build an app, sooner or later the technical question that most affects the budget appears: native, Flutter or React Native? The answer does not depend on which one is "trendy", but on what your app does, who will maintain it and how much you want to invest.
There is no best technology in the abstract. There is the one that fits your app's features, your team and your budget.
The three options in one sentence
- Native: one app for Android (Kotlin) and another for iOS (Swift). Maximum control, two developments.
- Flutter: a single codebase in Dart, with its own drawing engine, for Android and iOS (and web and desktop too).
- React Native: a single codebase in JavaScript or TypeScript that uses each system's native components.
Comparison
Criterion | Native | Flutter | React Native |
|---|---|---|---|
Shared code | No (two apps) | Yes, almost all | Yes, almost all |
Performance | The highest | Very good | Very good |
Access to phone features | Total and immediate | Through plugins; total if native code is needed | Through libraries; total if native code is needed |
Look and feel | Each system's own | Own and uniform | Each system's own |
Team profile | Two specialties | Dart | JavaScript / TypeScript |
Initial cost | Higher | Lower | Lower |
Maintenance | Two codebases | One | One |
When to choose a native app
Native makes sense when your app depends on features closely tied to the device or demands extreme performance:
- Augmented reality, real-time video or audio processing, 3D games.
- Heavy use of sensors, Bluetooth or deep integrations with the system.
- When you only need one platform (for example, an internal app only for Android).
The cost is doubling the work and the maintenance, so the benefit should justify it.
When to choose Flutter
- You want a highly polished interface that is identical on Android and iOS.
- Your team can learn Dart or already uses it.
- You also want to reach web or desktop with the same code.
- The app is a business app (catalogs, orders, calendars, dashboards) and does not depend on extreme device features.
When to choose React Native
- Your team already works with JavaScript or TypeScript and React.
- You want to share logic with your website (for example, with Next.js).
- You prefer each platform to keep its components and natural behavior.
- There is a library ecosystem that covers what you need.
And if you do not need an app
Before choosing technology, ask yourself whether an app is needed at all. If what you want is presence and contact, a fast site or a PWA may be enough; we look at it in landing page vs website. And if the app will sell, first see how much it costs to build an app in Ecuador.
What weighs more than the framework
Many apps fail for reasons unrelated to technology:
- The backend: data, users and business logic. See REST API vs GraphQL.
- Experience design: clear flows, error states, screens for several sizes.
- Publishing: accounts, reviews and store requirements (Google Play and the App Store).
- Maintenance: every new Android or iOS version may require adjustments.
Our practical recommendation
For most business apps in Ecuador (catalogs, orders, bookings, customer dashboards), a cross-platform solution (Flutter or React Native) offers the best balance of cost, timeline and quality. We choose between them based on the team that will maintain it and the integrations you need. We reserve native for cases where the device is the protagonist.
