React Native vs Flutter, What I Learned Shipping Apps in Both

I've shipped production apps in both frameworks. Here's my honest take on performance, developer experience, and when to pick each one.

React NativeFlutterMobileCross-Platform

Everyone has an opinion on React Native vs Flutter. Most of those opinions come from people who've only used one. I've shipped real apps in both, PintRadar and Moums in React Native, Creator Creator in Flutter, and the answer isn't what you think.

Performance, real world, not benchmarks

You've seen the benchmarks. Flutter wins by 2ms on animation frames. Here's what actually matters: both frameworks are fast enough for 95% of apps. The performance difference only shows up in heavy animations, complex lists, or real-time data streaming.

My React Native apps feel smooth. My Flutter app feels smooth. Users can't tell the difference. What they can tell is when your app crashes, and that's a code quality issue, not a framework issue.

Developer experience

React Native:

  • If you know React, you're 80% of the way there
  • JavaScript/TypeScript ecosystem is enormous
  • Debugging with Flipper is... fine. Not great, fine.
  • Hot reload works most of the time

Flutter:

  • Dart is easy to learn but you're learning a new language regardless
  • DevTools is genuinely excellent, best debugging experience I've had on mobile
  • Hot reload works every time. Every single time. It's flawless.
  • The widget tree inspector is way better than React DevTools for mobile

When I pick Flutter

I chose Flutter for Creator Creator because the app has complex custom animations and AI-driven UI that changes dynamically. Flutter's animation system (AnimationController, Tween, AnimatedBuilder) is more powerful and predictable than React Native's Animated API.

Flutter also wins when you want pixel-perfect control. Every widget renders the same on iOS and Android because Flutter draws its own UI instead of using native components.

When I pick React Native

I chose React Native for Moums because it's a chat-heavy, network-heavy app with real-time messaging and calls. React Native's ecosystem has better libraries for this, Firebase integration, push notifications, and WebSocket handling are all more mature.

React Native also wins when you're sharing code with a Next.js website. Moums shares some TypeScript utilities and API types with a web dashboard. That's not possible with Flutter.

The actual decision framework

Ask yourself these three questions:

  1. Does your team already know React? → React Native. Don't make people learn Dart for no reason.
  2. Do you need pixel-perfect custom UI with complex animations? → Flutter. The rendering engine is purpose-built for this.
  3. Are you sharing logic with a web app? → React Native. TypeScript + React on both platforms is a real advantage.

If you answered "none of these clearly apply", flip a coin. Both are good. Ship fast, iterate, and stop overthinking.

The best framework is the one you actually ship with.

I build both React Native and Flutter apps for clients. If you're not sure which one fits your project, let's talk.
