Both ship one codebase to iOS and Android. The right pick depends on your team, your UI ambition and where you're headed next. Here's how we actually decide.
Flutter and React Native both let one team ship to iOS and Android from a single codebase, which is usually the right call for a product startup. The choice between them is rarely about raw capability — both are production-grade — and almost always about fit: your team's existing skills, how custom your UI needs to be, and what platforms you'll want next.
We build with both, and we lead with Flutter. Below is the comparison we walk clients through, then the rule we use to decide.
| Flutter | React Native | |
|---|---|---|
| Language | Dart — one language, quick to learn | JavaScript / TypeScript — reuse web skills |
| UI rendering | Own engine (Skia / Impeller) — pixel-identical on every OS | Native components — platform-true, more per-OS variance |
| Performance | Compiled to native ARM; consistently smooth animation | Very good; a JS bridge can show at the edges of heavy UI |
| Consistency | Same on iOS, Android, web, desktop | Closer to each platform's native feel |
| Ecosystem | Younger but fast-growing; Google-backed | Mature, huge npm ecosystem; Meta-backed |
| Team fit | Best when the team commits to Dart | Best when you already have React / web engineers |
| Reach beyond mobile | iOS, Android, web and desktop from one base | iOS, Android (web via extra tooling) |
| Best for | Brand-led, animation-rich, multi-platform products | React-heavy teams, native-feel apps, web-skill reuse |
You want a distinctive, consistent brand UI, rich animation, and the option to reach web/desktop from the same codebase — and the team is happy to work in Dart.
Your team already lives in React/TypeScript, you want maximum native look-and-feel per platform, or you need a native module that's better supported there.
A single platform with deep OS integration (AR, advanced camera, heavy background work) is the whole product. We'll say so honestly.
Neither is universally better. Flutter gives you a pixel-consistent UI and one codebase across mobile, web and desktop; React Native lets you reuse React/JavaScript skills and lean on a huge ecosystem. We default to Flutter and switch to React Native when the team or product calls for it.
Both are fast enough for almost every app. Flutter compiles to native code and tends to hold up better under heavy custom animation; React Native is very performant too, though a JS bridge can occasionally show at the edges of complex UI.
If you're starting fresh and want one team to cover iOS, Android and later web, Flutter is our default. If you already have React engineers, React Native lets you move immediately with the skills you have.
Yes — native Swift and Kotlin when a platform's depth is the product. We recommend the approach with reasons; you decide.
A two-week discovery sprint ends with a recommended stack, a build plan and a fixed price — yours to keep either way.
