## Key Facts

{fact.label}: {fact.value}

({fact.source})

## Framework Origins and Philosophy

### React Native (Meta, 2015)

Philosophy: "Learn once, write anywhere". Uses native UI components, meaning buttons and lists are genuine platform elements. The JavaScript ecosystem integration is its superpower—NPM packages and React tools just work. Statista reports 38% cross-platform developer adoption.

The new architecture (Fabric + TurboModules) eliminates the JavaScript bridge, enabling direct native communication via JSI. GitHub shows 115K+ stars on the React Native repository. Stack Overflow surveys consistently rank it among the most loved frameworks. Gartner recommends cross-platform for 70% of enterprise mobile projects.

### Flutter (Google, 2018)

Philosophy: "Own every pixel". Renders using Skia/Impeller graphics engine—no platform UI components. Widget-based: everything is a widget (text, buttons, padding, rows). Google Developers reports 46% cross-platform adoption.

Multi-platform vision: web, desktop (Windows, macOS, Linux), and embedded devices from a single codebase. Impeller engine (Flutter 3.10+) pre-compiles shaders for consistently smooth animations.

## Head-to-Head Comparison

## Performance Analysis

### Startup Time & App Size

React Native with Hermes engine achieves cold starts of 1-2 seconds for medium apps. Flutter compiles to native code with fast startup but larger initial size: 5-7 MB iOS, 7-10 MB Android vs React Native's 3-5 MB.

### Animation & UI Rendering

Flutter's Impeller engine provides most predictable 60 FPS performance for animation-heavy apps. React Native's new architecture with JSI brings animation performance close to parity. For typical business apps, both perform excellently.

### Memory & Battery

Memory consumption varies based on architecture, not framework. Battery impact difference rarely exceeds 5%—well within measurement variance for real-world usage.

## Decision Framework: When to Choose Each

### Choose React Native When:

### Choose Flutter When:

## Development Cost Comparison

Framework choice has less impact on overall cost** than team experience, project scope, and development partner selection. Both frameworks deliver 30-40% cost savings compared to separate native codebases.

#### Developer Hourly Rates (US)

React Native: $75-$175/hour Flutter: $75-$175/hour (smaller talent pool)

#### Annual Maintenance

Budget 15-25% of initial development costs annually for maintenance, bug fixes, and platform updates.

## Frequently Asked Questions

### Should I choose React Native or Flutter for my app?

Choose React Native if your team has JavaScript/React expertise, needs native platform feel, or requires extensive third-party integrations. Choose Flutter if you need custom branded UI across platforms, are targeting web/desktop in addition to mobile, or building animation-heavy interfaces.

### Which is faster: React Native or Flutter?

Flutter's Impeller engine provides more predictable 60 FPS performance for complex animations. React Native's new architecture (Fabric/JSI) has significantly improved performance, making both frameworks comparable for typical business applications.

### How much code can be shared between iOS and Android?

Both React Native and Flutter enable 80-95% code sharing between iOS and Android platforms, according to Google and Meta benchmarks. Cross-platform approaches reduce development time by 20-40% compared to native development.
