Native vs React Native vs Flutter: Which Stack Should You Build Your App On?

Pick the wrong mobile stack and you’ll either re-write the app in 18 months or fight your tools forever. There’s no universally correct choice — only the right choice for your specific product, team, and timeline. This is the framework our mobile team uses on every selection.

Native iOS (Swift / SwiftUI)

Pick native iOS if: your app needs deep platform integration (HealthKit, Apple Pay, ARKit, Live Activities), you’re targeting App Store editorial features, your audience is iOS-heavy, or your team has Swift expertise.

Strengths: best performance, first access to new iOS features, smooth idiomatic UI, lower long-term maintenance cost on a single platform.

Trade-off: you’ll need a separate Android codebase if you want both stores.

Native Android (Kotlin / Jetpack Compose)

Pick native Android if: your audience is Android-heavy (most of the world outside the US is), you need deep Android platform features (Wear OS, Android Auto, Google services), or you’re targeting Asian, African, or Latin American markets where Android dominates.

Strengths: best Android performance, full platform feature access, mature tooling.

Trade-off: separate codebase from iOS.

React Native

Pick React Native if: you need both iOS and Android with 80%+ shared code, your team already knows React, your product is mostly UI and business logic rather than platform integrations, or you’re optimising for shipping speed with a small team.

Strengths: single codebase for two stores, large ecosystem, fast iteration, hot reload, easier to hire for than Flutter.

Trade-off: performance is “good enough” rather than excellent, deep platform features require native modules, occasional dependency churn.

Flutter

Pick Flutter if: you need pixel-perfect custom UI on both platforms, you’re building a design-rich app where the brand experience is core, your team can invest in learning Dart, or you want to extend to web and desktop from one codebase later.

Strengths: beautiful custom UIs, single codebase, excellent performance, growing ecosystem.

Trade-off: smaller talent pool than React Native, Dart is less common in the broader engineering market, less stable on web compared to React Native’s mobile-first focus.

The framework most teams should follow

1. Is the app inherently iOS-first or Android-first? → go native on the primary platform; decide later about the second.
2. Do you need both stores from day one with one team? → React Native (general purpose) or Flutter (design-heavy).
3. Does the app rely on cutting-edge platform features? → native, full stop.
4. Are you a content-driven app where shipping speed beats native polish? → React Native.

Don’t forget the marketing site

An app without a marketing site is invisible. Plan for a fast, conversion-focused marketing site, App Store Optimization (ASO) from our SEO team, and a launch programme with paid acquisition and lifecycle email.
