React Native app development with TypeScript and Expo
React Native app development means building iOS and Android apps in TypeScript with React, rendered with real native components. Hostlyx uses Expo to speed up builds and over-the-air updates, and shares logic and types with your React web app where it helps. We build and host the backend and admin panel too, and quote a fixed price first.
React Native lets one team build iPhone and Android apps with React and TypeScript, the same tools used for most modern web apps. The interface uses real native components, so lists, text inputs and navigation behave as users expect on each platform, while most of the code is shared between the two.
It is the natural choice if you already run a React or Next.js web app. Validation rules, API clients, TypeScript types and business logic can live in a shared package used by both web and mobile, so a change to how prices or orders work is made once and stays consistent everywhere.
We build with Expo, which handles native builds in the cloud, simplifies push notifications and lets small fixes reach users through over-the-air updates without waiting for a full store review. When a feature needs native code, we write it in Swift or Kotlin as a module, so you get the speed of Expo without giving up anything the platform offers.
What is included
TypeScript throughout
The app written in strict TypeScript, so data from your API is typed end to end and many errors are caught before a build ever reaches a phone.
Code shared with your web app
A shared package for API clients, validation, types and business rules, used by both your React web app and the mobile app to keep them consistent.
Expo builds and updates
Cloud builds and store submission through Expo, plus over-the-air updates for JavaScript fixes, so small corrections reach users without a full store release.
Native modules when needed
Where a library falls short, we write native Swift or Kotlin modules and expose them to React Native, so the app is never limited by the framework.
Store publishing
App Store and Google Play listings, privacy details and submissions handled under your own developer accounts, with releases kept in step on both platforms.
Backend, admin and hosting
One API serving your website and your apps, plus an admin panel, built and hosted by us so web, mobile and server are maintained together.

How we work
-
Review your stack
We look at your existing web app, API and team to see how much code mobile can share and what React Native needs.
-
Fixed written quote
You receive a written quote listing screens, shared code, native modules and backend work included, before any development starts.
-
Set up the shared code
We organise a monorepo or shared package so web and mobile use the same types, API client and business rules from the start.
-
Build and test
Screens are built in TypeScript and tested on real iPhones and Android phones, with preview builds shared through Expo and the store testing tracks.
-
Release and update
We publish to both stores, then ship JavaScript fixes over the air and full store releases when native changes are involved.

Questions people ask
How much does React Native app development cost?
Cost depends on the number of screens, how much code can be shared with your web app, any native modules required, and the backend and admin panel. Reusing existing web logic can reduce the work. After a scoping call we send a fixed written quote listing everything included.
Can a React Native app share code with my React website?
Yes, though not the screens themselves. Business logic, validation, API calls, TypeScript types and state handling can be shared through a common package. The interface is written separately with native components, so each app still feels right on its platform.
What is Expo, and do you use it?
Expo is a set of tools around React Native that handles native builds in the cloud, push notifications and over-the-air updates. We use it on most projects because it speeds up delivery, and we add custom native code to an Expo app when a feature needs it.
Is React Native as good as a native app?
For most business apps users cannot tell the difference, because React Native renders real native components. Native Swift or Kotlin is still the better choice for heavy graphics, intensive background processing or the newest platform features. We recommend whichever suits your app after scoping.
Can you host the backend for my React Native app?
Yes. We build or extend the API, database and admin panel, and host them on our own servers with SSL, backups and monitoring. One backend can serve both your website and your apps, maintained by the same team.
