One of the first technical decisions in any app project is whether to build cross-platform with a framework like Flutter, or native with Kotlin for Android and Swift for iOS. Founders often hear strong opinions on both sides. Here is a balanced view to help you decide.
Quick comparison
| Flutter (cross-platform) | Native (Kotlin + Swift) | |
|---|---|---|
| Codebase | One codebase for Android and iOS | Two separate codebases |
| Time and cost | Usually lower for both platforms | Higher — two apps to build and maintain |
| Performance | Excellent for most business apps | Best possible, especially for heavy graphics or processing |
| Device features | Most features via plugins; custom native code when needed | Full, immediate access to every platform API |
| UI consistency | Same design on both platforms | Follows each platform's native look and feel |
| Maintenance | One team, one set of updates | Two sets of updates for every change |
When Flutter is the better choice
- You need both Android and iOS on a sensible budget.
- It is a business app — e-commerce, booking, fintech dashboards, education, delivery or internal tools.
- You want to launch an MVP quickly and iterate.
- You want one team to own the whole app.
When native is the better choice
- The app relies heavily on device hardware — advanced camera, Bluetooth, AR or background processing.
- Graphics-intensive apps such as games or video editing.
- You need new platform features on day one.
- You only target one platform and plan to stay that way.
What about React Native?
React Native is another popular cross-platform option, especially for teams that already use React on the web. Flutter and React Native are both mature. The more important factors are the team's experience and the app's requirements.
Our recommendation
For most business apps we start with Flutter, because it gets you to both app stores faster and keeps maintenance simple. Where a feature needs it, we add native code for that part only. If your app is hardware- or graphics-heavy, we recommend native from the start.

Frequently asked questions
Is Flutter good for production apps?
Yes. Flutter is a mature framework from Google used for production apps across e-commerce, fintech and many other categories.
Is a Flutter app slower than a native app?
For most business apps the difference is not noticeable. Native has an edge for graphics-heavy or hardware-intensive apps.
Can a Flutter app use native device features?
Yes. Flutter uses plugins for most device features, and developers can write native Kotlin or Swift code for anything specialised.
