React Native apps for iOS and Android, built once and shipped to both.
We build iOS and Android apps with React Native: one codebase, near-native performance on the new architecture, and senior engineers who own the work from discovery through app store launch. We've built and contributed to dozens of React Native apps over six years, for startups racing to market and for larger teams modernising the mobile presence they already have.
One codebase, two platforms, and performance close to native.
React Native lets you deliver a fast, polished app across iOS and Android from a single codebase, so you skip the cost of running two parallel native builds while keeping the experience your users expect. Here's why we reach for it.
One codebase across iOS and Android
Write your app logic once and ship to both platforms at the same time. React Native shares 70 to 90 percent of code across iOS and Android, which cuts build and maintenance time and keeps feature parity. Your team moves faster, your users get a consistent experience, and your budget stretches further.
Near-native performance on the new architecture
React Native's new architecture rivals native performance benchmarks. The updated rendering system, concurrent features, and rebuilt bridge deliver smooth 60fps animations, fast startup, and responsive interactions. Microsoft, Shopify, and Discord run React Native in apps used by billions of people.
A large ecosystem, maintained by Meta
Meta builds and maintains React Native, and runs it in Facebook, Instagram, and WhatsApp. The ecosystem brings more than 2,000 open-source libraries, mature tooling, and a global community of experienced developers, so you're rarely blocked waiting on a missing capability.
An investment that holds its value
Mobile moves quickly, and React Native keeps pace. Over-the-air updates let you fix bugs and ship features without waiting on an app store review. When a feature needs native capabilities, the architecture takes custom native modules cleanly. You scale from prototype to production without a rewrite, and the code stays yours to own.
Faster to market
Fast refresh during development, shared business logic, and one testing setup all push toward velocity. You can launch an MVP in weeks rather than months, then iterate on real user feedback while a native-only build is still shipping its first platform.
Mobile app development, end to end. From a first build to a platform serving millions.

Where React Native earns its place. Six situations where it tends to be the right call.
Startups building an MVP
You need to validate product-market fit fast, without burning runway on separate iOS and Android builds. React Native lets you test the concept on both platforms at once, gather real usage data, and iterate quickly on what you learn.
Enterprise modernisation
Legacy apps that need separate iOS and Android teams slow releases and drift apart over time. Consolidating onto React Native lowers mobile engineering cost by 30 to 40 percent and speeds up how often you can ship features.
E-commerce and retail
Shopping apps need sharp product displays, smooth scrolling, and reliable payments. React Native holds up under high traffic and makes it easy to A/B test checkout flows and promotions.
Social and community platforms
Real-time messaging, media sharing, notifications, and busy feeds have to work cleanly across devices. React Native's performance work and over-the-air updates let you respond to how people actually use the app.
Fintech and banking
Financial apps need solid security, offline functionality, and compliance with platform rules. React Native supports biometric authentication and secure storage, and drops to platform-specific code where regulation calls for it.
Healthcare and wellness
HIPAA-compliant tracking, telehealth video, and device connectivity all need a dependable architecture. React Native scales from a personal wellness MVP up to a regulated platform serving millions of people.
Six ways teams work with us on mobile. From a first scope to performance work on a live app.
Discovery and strategy
We start by understanding your users, your business model, and your technical constraints. Discovery covers competitive analysis, technical feasibility, platform guidance, and architecture planning. You get a clear roadmap, a realistic timeline, and a transparent budget before we write a line of code.
MVP development
Launch a mobile app in 6 to 12 weeks on a framework we've used many times. We focus on the core user flows, the essential features, and a clean architecture that scales. The MVP ships with analytics, crash reporting, and feedback mechanisms, so you learn what's working straight away.
Full-scale app development
Production apps with a considered architecture, full test coverage, security hardening, and performance work. We handle complex state, offline sync, third-party integrations, backend APIs, and app store submission, so the app launches ready for real users and real revenue.
Native migration
Moving from separate iOS and Android codebases to React Native is something we've done many times. Our incremental approach lowers risk: we move feature by feature, keep both codebases running through the transition, and avoid disruption for your users. Most migrations land in 3 to 6 months and cut ongoing cost by 40 to 60 percent afterwards.
Performance optimisation
If you already have a React Native app that feels slow, we profile the bottlenecks, tidy up rendering, reduce bundle size, improve startup time, and add lazy loading. Most apps see a 30 to 50 percent performance improvement within four to six weeks.
Senior engineers alongside your team
When you need senior React Native experience without a full-time hire, our engineers work inside your team: sprint planning, code review, and pair programming included. We fill the gap in mobile expertise and hand knowledge across to your people as we go.
Senior engineers who own the outcome. Six years of React Native, dozens of apps shipped.
Six years and dozens of mobile apps
We've built React Native apps since the framework's early days. The team has worked through the edge cases, the performance pitfalls, and the architecture patterns, so you get that accumulated experience without learning the hard lessons yourself.
Enterprise standards, startup pace
You work with senior engineers who carry four to ten years of mobile experience and can architect for scale while moving quickly. No juniors finding their feet on your project.
End to end ownership
We stay past launch. From first strategy through app store release and beyond, we own the backend APIs, the CI/CD pipelines, the monitoring, and the ongoing optimisation. One team, accountable for the outcome.
Direct communication
Weekly demos, a shared Slack channel, and live access to the code. You always know what's happening, what's next, and which risks we're managing. No surprises.

React Native, answered straight. The questions teams ask us most before they start.
How does React Native compare to native iOS and Android development?
React Native delivers 90 to 95 percent of native performance while lowering development cost by 30 to 40 percent and time-to-market by two to three times. For most apps, users can't tell the difference. Native development earns its place when you're building platform-specific features such as advanced ARKit work; for most other cases, React Native is the practical choice.
Can React Native handle complex apps, or only simple ones?
React Native powers Facebook, Instagram, Discord, Shopify, Microsoft Teams, and thousands of enterprise apps with millions of users. Meta runs it in apps with billions of monthly users, so it will hold your requirements. The new architecture closed the earlier performance gaps, which makes React Native suitable for demanding applications.
What if I need a feature React Native doesn't support out of the box?
React Native integrates cleanly with native modules. When you need a platform-specific capability, we write the native code in Swift or Kotlin and bridge it into your app. The architecture is designed for exactly this, so you keep the efficiency of React Native and reach full native capability where you need it.
How long does it take to build a React Native app?
MVPs usually take 6 to 12 weeks. Full-scale apps run from 3 to 6 months depending on complexity. React Native is two to three times faster than building separate iOS and Android apps, and proven patterns and reusable components from our portfolio speed things up further.
Am I locked into React Native, or can I switch later?
React Native is open source and maintained by Meta, so nothing is proprietary. If you ever needed to migrate to native you could, though in practice clients tend to scale on React Native for years rather than move off it. Your investment stays protected either way.
Do you handle app store submissions and approvals?
Yes. We manage the full submission process for both the iOS App Store and Google Play, including account setup, metadata, screenshots, and the compliance requirements each store applies, then see the review through to approval.
