One codebase, two stores
A typical business app shares 85 to 95 percent of its code. You fund one team and one backlog, and iOS and Android ship the same features on the same day.

React Native
One TypeScript codebase for iOS and Android, built by engineers who know exactly where the framework ends and native code begins.
What it is
React Native lets one team ship iOS and Android from a single TypeScript codebase, with 85 to 95 percent of the code shared in a typical business app. That is the economics in one sentence: one backlog, one release train, and every feature lands in both stores at the same time instead of being built twice and slowly drifting apart.
It wins most often when you already have React on the web. Your engineers know the component model, the state patterns and the tooling on day one, and the design system and business logic you built for the browser carry over to mobile. No other cross-platform stack converts an existing web team into a mobile team this cheaply, and the React hiring pool is the largest in the industry when you grow.
It is not native code, and we do not pretend it is. Camera pipelines, Bluetooth, widgets and heavy real-time graphics still mean writing Swift and Kotlin modules, and every React Native upgrade costs real engineering time. We scope that boundary before the project starts, budget the maintenance honestly, and tell you plainly when your app would be better served by Flutter or two native codebases.
Why it works
Your web team is your mobile team
React Native is React with native building blocks. Engineers who ship your web app are productive in the mobile codebase within days, not months.
Fixes without the store queue
Over-the-air updates push JavaScript-level fixes directly to users, within store policies. A bad release stops meaning a two-day review wait.
Native where it earns it
Where the framework ends, we write Swift and Kotlin: payments, camera, Bluetooth, background tasks. Planned as native modules up front, not discovered in month three.

How we build with it
01
Scope the native boundary
Before estimating anything we list every feature that needs native code: sensors, payments, background work. That list decides the architecture and makes the estimate honest.
02
Foundation in week one
Expo or bare workflow, navigation, state management, design tokens and CI with store delivery are decided and running in the first week. Slow foundations are where cross-platform projects die.
03
Betas from week two
The app goes to TestFlight and a Play internal track early, and every sprint ships there. Stakeholders judge working builds on their own phones, not screenshots.
04
Upgrades as routine, not crisis
We keep the app within one release of React Native stable, budget the upgrade work explicitly, and leave you a maintenance plan with real numbers instead of a surprise.
What you get
Production iOS and Android apps from one TypeScript codebase
CI/CD pipeline with automated delivery to both stores
Native Swift and Kotlin modules where required, documented
Shared design system, aligned with your web app where one exists
Automated test suite: unit, integration and end-to-end
Maintenance and upgrade plan with effort estimates
Common questions
Is React Native fast enough for our app?
For most business apps, yes: the new architecture runs on JSI with the Hermes engine, and lists, forms and dashboards are indistinguishable from native for users. The honest exceptions are heavy real-time graphics, video processing and games. If your app lives there, we will say so and point you to Flutter or native instead.
How much code is actually shared between iOS and Android?
In the apps we ship, 85 to 95 percent. The rest is native modules, platform configuration and small per-platform UI adjustments. The share drops when an app leans heavily on platform hardware, which is exactly what we scope before you commit.
What does maintenance really cost?
Plan for a React Native and dependency upgrade cycle two or three times a year, a few engineer-days each when done on schedule. Skipping upgrades for a year turns those days into weeks, so our maintenance plans keep the cadence. Expo has cut this cost significantly in recent years.
React Native or Flutter?
If you have a React web team or share logic with a web product, React Native leverages what you already own. If your product is design-led with heavy custom UI and animation, Flutter's own renderer is the better fit. We build both, and the recommendation you get is written down with reasons.
