Flutter vs React Native: which should you choose?
Choose Flutter for polished, animation-heavy consumer apps that need an identical custom look on both platforms; choose React Native if your team already works in JavaScript/React or you're building business tools. Both ship iOS and Android from one codebase at roughly 30–50% less cost than two native apps, so the bigger decision is cross-platform vs native, not Flutter vs React Native.
Flutter vs React Native, at a glance
| Feature | Flutter | React Native |
|---|---|---|
| Language | Dart | JavaScript / TypeScript |
| Rendering | Own engine (pixel-perfect, identical UI) | Native components |
| Best for | Custom, animation-heavy consumer apps | JS-stack teams, business tools |
| UI consistency | Identical across platforms | Closer to each platform's native feel |
| Team ramp-up | New language (Dart) — easy to learn | Familiar to web/React teams |
| Code sharing with web | Possible (Flutter web) | Strong (shares with React web) |
| App size | Slightly larger | Moderate |
| Maturity / ecosystem | Mature, Google-backed | Mature, Meta-backed |
Which should you choose?
If the app is brand-critical, visually rich or animation-heavy and you want it to look identical on iOS and Android, choose Flutter.
If your team is already in the JavaScript/React ecosystem, or you're building dashboards and business tools, choose React Native.
For most SMEs and startups the real win is simply going cross-platform — either framework saves roughly 30–50% versus two native apps. I'll recommend honestly based on your app, team and budget.
Frequently asked questions
Is Flutter or React Native faster?
Both are fast enough for the vast majority of apps. Flutter's own rendering engine gives an edge for heavy custom animation; React Native renders with native components.
Which is cheaper to build?
Both cost roughly the same and both are far cheaper than two native apps — the ~30–50% saving comes from sharing one codebase, not from the framework choice.
Can I reuse code with my website?
React Native shares more naturally with a React web app; Flutter also offers web, though sharing is less common in practice.
