Flutter vs React Native in 2025: What We Actually Use and Why

The Question Everyone Asks

"Flutter or React Native?" is the most common question we get from clients planning a mobile app. After shipping over 10 cross-platform apps at NEXUS Infotech, here's our actual answer.

It depends on one thing: your team's strongest language.

Everything else is secondary. But since that's not satisfying, here's the full breakdown.

Flutter Wins When:

1. You want pixel-perfect custom UI

Flutter renders every pixel itself — it doesn't use native components. This means your app looks identical on iOS and Android, and you can build custom animations that would be painful in React Native.

Our health app PULSE used Flutter's custom painter API to build real-time biometric charts that would have required a native module in React Native.

2. You need smooth 60fps animations

Flutter's Skia/Impeller renderer handles complex animations natively. React Native's bridge can introduce jank on lower-end Android devices.

3. Performance is critical

Flutter compiles to native ARM code. In our benchmark tests on a mid-range Android, Flutter consistently outperformed React Native by 15–25% on animation-heavy screens.

React Native Wins When:

1. Your team writes TypeScript

If your team already writes React for web, the transition to React Native is weeks, not months. Shared business logic, shared state management patterns, shared tooling.

2. You need a smaller binary

Flutter apps carry the entire Flutter runtime (~5MB overhead). For simple utility apps, React Native ships smaller.

3. You need Expo

Expo has transformed React Native DX. OTA updates, EAS Build, and the managed workflow let small teams ship fast without native tooling knowledge.

The Number That Matters More Than Framework

D30 retention.

We've shipped apps in both frameworks. The ones with high retention aren't the ones with the "better" framework — they're the ones where we spent two weeks on onboarding UX and push notification strategy.

Our Default Stack in 2025

• New client projects with custom UI: Flutter + Riverpod + Fastlane
• Projects with existing React web team: React Native + Expo + TypeScript

Both stacks work. Choose based on your team, not the benchmark articles.
