Why React Native for Your Business
Mobile apps from your existing React team. No new hires needed.
Reuse Your React Team
If you already have React engineers, they can build your mobile app. React Native shares the same component model, so your team is productive on mobile within weeks.
Shared Web & Mobile Code
Business logic, API clients, state management, and validation code work across your React web app and React Native mobile app. You write critical logic once and deploy everywhere.
Over-the-air Updates
React Native supports pushing updates directly to users without app store review cycles. Bug fixes and small features reach your users in hours, not the 1-3 days a store review takes.
Battle-tested at Scale
Instagram, Shopify, Discord, and Coinbase run on React Native. These aren't experiments. They're production apps serving hundreds of millions of users.
Largest Mobile Community
React Native has the most active open-source mobile community and richest library ecosystem. Camera modules, biometrics, maps integration: the solution already exists.
What We Build With React Native
Cross-platform mobile apps from a single TypeScript codebase.
Cross-Platform Mobile Apps
iOS and Android from a single TypeScript codebase. Expo managed workflow for faster iteration, or bare workflow when you need deep native access. React Native 0.83, New Architecture, Hermes engine.
React Web-to-Mobile
Already have a React web app? We share components, business logic, and design tokens between your web and mobile codebase. 60-80% code reuse without rebuilding from scratch.
MVP & Startup Apps
Validate your idea on both platforms in 8-12 weeks. Expo's managed workflow means faster builds, over-the-air updates, and no Xcode/Android Studio dependency during early iterations.
Enterprise Mobile Apps
Offline-capable, role-based access, SSO integration, and compliance-ready. Bare workflow for maximum native control. Custom native modules via Expo Modules API or TurboModules when the SDK isn't enough.
App Performance Optimization
Migrate from legacy bridge architecture to New Architecture. Hermes engine adoption for 30% faster cold starts and 20-30% lower memory usage. Bundle size reduction, lazy loading, 60fps animation targets.
Native App Migration
Move from Swift-only or Kotlin-only codebases to React Native. Brownfield integration for incremental adoption - add React Native screens to your existing native app without a full rewrite. Expo SDK 55's new brownfield package makes this smoother than ever.
When React Native Makes Sense
The right framework for the job, not the trending one.
Need iOS + Android from one team
Single codebase, shared logic, consistent UX. Ship both platforms simultaneously instead of maintaining two separate apps and two separate teams.
Your team already knows React
React Native uses the same component model, hooks, and state management. Your web developers can contribute to mobile without learning Swift or Kotlin.
Speed to market matters
Expo’s managed workflow, over-the-air updates, and hot reloading mean faster iteration. MVP in 8-12 weeks, not 6 months.
Budget-conscious but quality-focused
Cross-platform cuts 30-40% vs. native iOS + native Android. You’re not sacrificing quality - Instagram, Shopify, Discord, and Coinbase all run React Native in production.
If your app is primarily 3D/gaming (Unity or native), needs extreme low-level hardware access (Bluetooth LE edge cases, heavy AR), or your team is already deep in Dart, you may want to explore Flutter or go fully native. For SEO-critical marketing sites, Next.js is the better call. For complex backend needs alongside your mobile app, see our Node.js and Python services.
React Native vs Flutter: When You Need What
We build with both. Here's how we decide.
React Native (JavaScript/TypeScript)
Best for
Teams with existing JavaScript/React expertise, code sharing with a React web app, brownfield integration into existing native apps
Why
React Native uses the same component model, hooks, and state management as React. Your web developers can contribute to mobile without learning a new language. JavaScript developers outnumber Dart developers roughly 20:1, making hiring easier.
Key context
React Native 0.83 ships with the New Architecture by default. The old performance criticisms were about the JavaScript bridge, which no longer exists. With Fabric, TurboModules, and Hermes, React Native now achieves near-native performance at 60fps on most devices.
Flutter (Dart)
Best for
Pixel-perfect custom UI that looks identical on both platforms, heavy animation or graphically intensive apps, mobile + web + desktop from one codebase
Why
Flutter has surpassed React Native in GitHub stars (170K vs 121K) and shows 46% cross-platform market share vs React Native’s 35%. But market share doesn’t equal ‘better’ — it depends on your team and project.
Key context
Teams starting fresh with no existing JavaScript investment, apps targeting mobile + web + desktop from one codebase (Flutter’s widget engine renders everywhere), or when pixel-perfect custom UI is the top priority.
Many companies use both. React Native for business apps where platform-native feel matters, Flutter for consumer apps where custom UI is the priority. We build with both — see our Flutter services.
From Idea to App Store
Working software every sprint, not just progress updates.
Discovery & Architecture (1-2 weeks)
Define screens, user flows, and technical approach. Decide between Expo managed vs. bare workflow. If you have an existing app, we audit it and plan the migration path. Deliverable: technical spec and Figma wireframes.
Design System & Prototyping (1-2 weeks)
Build a shared component library that works across iOS and Android. Set up Storybook for React Native to review components in isolation. Design tokens shared with your web app if applicable.
Development & Iteration (6-16 weeks)
Sprint-based development with preview builds via EAS for stakeholder testing on real devices. Weekly demos. Over-the-air updates for rapid feedback loops. No waiting for App Store approvals during development.
QA, Performance & Launch (1-2 weeks)
Device testing across iPhone, Android flagships, and budget devices. Performance profiling with Hermes. Lighthouse-equivalent audits for mobile. App Store and Play Store submission via EAS Submit.
Post-Launch & Maintenance
OTA updates for JavaScript changes (no resubmission). Native updates through EAS Build. Monitoring with Sentry + crash analytics. Ongoing feature development as needed.
