React Native App Development Company

PerfectionGeeks is a React Native app development company that builds iOS and Android apps, and often a web app, from one TypeScript codebase. We use React Native's New Architecture, Expo where it fits and native modules in Swift and Kotlin when an app needs device features or extra performance. Most apps share the large majority of their code across platforms, which usually cuts cost and time compared with two separate native apps. A React Native MVP typically costs $15,000–$40,000 and launches in 8–12 weeks; a full-featured app costs $40,000–$100,000.

  • React Native suits most business, commerce, social, booking and content apps that need iOS and Android quickly.
  • Since version 0.76, the New Architecture is on by default, improving performance and native interoperability.
  • Over-the-air updates can only change JavaScript and assets; native changes and new features still go through App Store and Google Play review.
  • Choose native or add native modules for heavy graphics, AR, advanced Bluetooth or very complex animations.
  • Typical cost: $15K–$40K for an MVP, $40K–$100K for a full app, $100K–$250K+ for enterprise apps.

When React Native Is the Right Choice

Many successful products mix both: a React Native app with a few native screens or modules where they matter.

Choose React Native whenConsider native when
You need iOS and Android, often with web, on one budgetThe app relies on heavy 3D graphics, games or AR
Your team already uses React or JavaScriptYou need deep, low-level access to new OS features on day one
Most screens are forms, lists, feeds, maps and mediaAnimations and real-time processing are the core of the product
You want fast releases and over-the-air fixesYou only target one platform

How We Build React Native Apps

  • New Architecture by default

    Fabric rendering and TurboModules for faster, more predictable performance.

  • Expo or bare workflow

    Expo and EAS for faster builds and updates in most apps; bare React Native when the project needs unusual native configuration.

  • TypeScript and clean structure

    Typed code, feature-based folders and shared design components.

  • Offline-first data

    Local storage and sync so key screens work without a connection.

  • Over-the-air updates done properly

    EAS Update or similar for JavaScript fixes, used within App Store and Google Play rules.

  • Security

    Secure storage, certificate pinning where needed, obfuscation and no secrets in the app bundle.

Frequently Asked Questions

How much does React Native app development cost?
Typically $15,000–$40,000 for an MVP, $40,000–$100,000 for a full-featured app and $100,000–$250,000 or more for enterprise apps.
How long does it take to build a React Native app?
About 8–12 weeks for an MVP, 3–6 months for a full-featured app and 6–10 months for enterprise apps.
Is React Native performance as good as native?
For most business apps, users cannot tell the difference, especially with the New Architecture and Hermes. Graphics-heavy games, AR and complex real-time processing are better built natively.
How much code can be shared between iOS and Android?
Most app code is shared; platform-specific parts are usually limited to some native modules, permissions and small UI adjustments.
React Native or Flutter: which is better?
Both are strong. React Native suits teams with React skills and apps that should use native components; Flutter suits highly custom, identical UI across platforms.
Can I update my app without App Store review?
You can push JavaScript and asset fixes over the air within store rules. Native code changes and significant new features still need store review.
Should we use Expo?
For most new apps, yes: Expo speeds up builds, updates and native configuration. We use the bare workflow when a project needs it.
Can you migrate our native or Xamarin app to React Native?
Yes. We plan a phased migration so users keep a working app throughout.
Can React Native apps use device features?
Yes: camera, GPS, Bluetooth, biometrics, push notifications, payments and health data, through libraries or custom native modules.
Can you build a web app from the same code?
Often, yes, with React Native Web for shared screens, or a separate React web app sharing business logic.
Can I hire dedicated React Native developers?
Yes, as a dedicated team or added to your in-house team.
Do you provide support after launch?
Yes: updates for new iOS and Android versions, library upgrades, monitoring and new features.
