Every mobile project starts with the same question: build once for both platforms, or build natively for each? The answer depends on your app, your team and your budget.
The options
| Flutter | React Native | Native (Kotlin / Swift) | |
|---|---|---|---|
| Codebase | One (Dart) | One (JavaScript / TypeScript) | Two separate apps |
| UI consistency | Very high, own rendering | Uses native components | Platform-perfect |
| Performance | Excellent for most apps | Very good for most apps | Best for heavy graphics or hardware |
| Team fit | New or mobile-focused teams | Teams already using React | Dedicated iOS and Android teams |
| Cost and speed | Lower, faster | Lower, faster | Higher, slower |
When cross-platform is the right call
- Business apps: field sales, service, warehouse, HR and customer portals
- Apps that mainly display and capture data from your ERP or backend
- Projects where time to market and budget matter
When to go native
- Heavy use of device hardware, AR, or advanced Bluetooth
- Graphics-intensive apps or games (where engines like Unity are often better still)
- Apps that must adopt new platform features on day one
Do not forget the backend
The app is only half the product. Authentication, APIs, offline sync, push notifications and ERP integration determine whether the app is genuinely useful.
