CrestCoder is a dedicated React Native app development company helping startups and enterprises across India, Australia, South Africa, and the UK ship high-quality iOS and Android apps from a single codebase — at a fraction of the cost of building two separate native apps.
We reply within 24 hours — no obligation.
React Native is Meta's open-source framework for building native mobile applications using JavaScript and React. It solves the single biggest challenge in mobile development — the cost and complexity of building and maintaining two separate codebases for iOS and Android.
Whether you are launching your first app or scaling a live product, React Native gives your team a productive, well-documented foundation that reaches both platforms simultaneously.
Discuss Your App IdeaUp to 90% of code is shared between iOS and Android, dramatically cutting development time and cost.
Renders using real native UI components — not a web view — giving users a smooth and responsive experience.
Developers see code changes in real time without rebuilding the app, speeding up iteration cycles significantly.
A single team ships to both app stores simultaneously instead of running two parallel development projects.
Over-the-air code updates can be pushed to users without waiting for App Store or Play Store review cycles.
Adding features or maintaining the app requires half the engineering effort compared to separate native apps.
Regular updates, a vast library ecosystem, and thousands of active contributors worldwide.
From custom apps to enterprise migrations — our dedicated React Native team covers the full delivery lifecycle.
Bespoke React Native applications built from the ground up — consumer apps, enterprise tools, marketplace platforms, and SaaS mobile products. Tested on real iOS and Android devices before release.
Intuitive, polished interfaces following iOS Human Interface Guidelines and Android Material Design principles — all within a single shared design system. Figma designs ready for development handoff.
We integrate React Native frontends with RESTful APIs, GraphQL, Firebase, Stripe, Twilio, Google Maps, and custom Laravel or Node.js backends. Push notifications, real-time data, and offline functionality included.
Migrate legacy iOS or Android apps — built in Swift, Kotlin, Java, or Objective-C — to a unified React Native codebase. Preserves all functionality while dramatically reducing future development costs.
Flexible monthly retainer plans covering OS updates, security patches, performance improvements, crash monitoring, and user-requested features — for both iOS and Android simultaneously.
Hire senior React Native developers on a monthly retainer. They work exclusively on your project, attend your stand-ups, use your tools, and are available via Slack or Teams with time-zone overlap for AU, UK, and ZA clients.
