Choosing the Right Mobile App Tech Stack in 2024

One of the first and most important decisions when building a mobile app is your tech stack. Get it wrong and you'll spend years fighting the limitations of your choice. Get it right and you'll ship faster, hire easier, and scale better.

Here's our analysis based on 50+ mobile apps built in 2023-2024.

Option 1: React Native

React Native is JavaScript/TypeScript with React — one codebase that compiles to native iOS and Android code. It's the most popular cross-platform choice and has the largest ecosystem.

Pros: Fastest time to market, lowest cost, largest talent pool, strong community. Cons: Performance ceiling for graphics-heavy apps, occasional 'bridging' issues with native APIs.

Best for: Startups, MVPs, apps that are mostly UI/UX with standard native features.

Option 2: Flutter

Flutter is Google's framework using the Dart language. It renders its own UI instead of using native components, which gives it incredibly consistent cross-platform appearance.

Pros: Beautiful UI, consistent design across platforms, excellent performance, growing ecosystem. Cons: Dart is a less common language (harder to hire for), larger app size.

Best for: Apps where visual consistency and custom UI are critical.

Option 3: Native iOS (Swift) + Android (Kotlin)

Two separate codebases, each built with the platform's native language. The highest performance and deepest platform integration, but also the most expensive.

Pros: Best performance, full access to all native APIs, best UX on each platform. Cons: 2x the development cost, 2x the maintenance.

Best for: Apps that push hardware limits (AR/VR, real-time graphics), or when the absolute best native experience is required.

Our Recommendation for 2024

For 80% of apps: start with React Native. The talent pool is huge, the ecosystem is mature, and Expo (the React Native framework) has made deployment significantly easier.

If your app is heavily UI-focused with custom animations and you have budget: consider Flutter.

If you're building a game, AR app, or something that needs extreme performance: go native.
