React Native, Flutter or Swift and Kotlin. A practical guide to decide based on your budget, team and product.
The right question
It isn't about which technology is better in the abstract, but which one fits your product. A booking app doesn't have the same needs as a video-editing app.
When cross-platform makes sense
React Native and Flutter let you share most of the code between iOS and Android.
- You need to launch on both platforms with a single team.
- Your app is mostly forms, lists, payments and content.
- You want to iterate fast and validate the product in the market.
When native makes sense
Swift and Kotlin are still the best option in some cases.
- Heavy use of camera, audio, sensors or real-time graphics.
- Widgets, deep system integrations or newly released features.
- Large teams dedicated to each platform.
Our recommendation
For most companies, starting cross-platform with a carefully crafted design is the fastest way to market. If a feature later requires it, that part can be written natively without rebuilding the whole app.
