Native screens in TypeScript
iOS and Android screens built from React Native components, typed with the TypeScript your web team knows.
The Problem
React Native Apps Stuck on an Old Version Nobody Wants to Touch
React Native projects age fast: an old version, a pile of native patches, and builds that only work on one laptop. Every update after that gets harder to ship.
01 · Frozen version
The app runs a React Native version nobody dares upgrade.
We upgrade in planned steps onto the New Architecture, testing each step.
02 · One laptop
The build only works on one developer's laptop.
EAS Build makes every build reproducible from a clean checkout.
03 · Dead libraries
Half the native libraries are deprecated or abandoned.
We replace abandoned libraries with maintained ones or Expo modules.
04 · Team gap
Your React web team can't safely change the app.
Shared TypeScript types and familiar patterns let your React developers contribute.
Your React Native app was built three years ago on a version nobody dares upgrade. The build only works on one developer's laptop, and that developer left. Half the native libraries are deprecated, a push notification patch lives in a folder nobody understands, and Apple's newer Xcode requirements keep piling up. Your web team writes React every day, yet nobody can safely change the mobile app. So small fixes wait for months.
We start by moving the project onto Expo and EAS, so any developer can build it from a clean checkout. Then we upgrade React Native in planned steps onto the New Architecture, replace abandoned libraries, and share TypeScript types with your web app. Your React developers can read the code again, and fixes reach users in days, not months.
Native UI, not a web view
React Native renders real iOS and Android components, so scrolling and gestures feel native.
Expo and EAS builds
Reproducible builds and store submissions from EAS, not from one developer's laptop.
Shared with your web team
TypeScript types and logic shared with your React web app, reviewed by the same people.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built mobile and web products for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why React Teams Trust Us With Their Mobile App
React Native apps stay healthy when your web team can read them and upgrades keep moving. These habits keep yours that way.
Pull requests your team can read
We follow your web team's TypeScript and linting rules in the app. Your developers review our pull requests and can take over without a translation step.
Upgrades planned, not postponed
We keep React Native and Expo SDK versions current during support. Skipped upgrades are how apps end up frozen on a version nobody can move.
Native code when it's right
Some features need Swift or Kotlin, and we write it when they do. We won't stack plugins on a problem one native module would solve.
Real devices on both platforms
We test on iPhones and Android phones, including slower ones, before every release. JavaScript-heavy screens show their lag on older hardware first.
Your accounts and repository
Store accounts, the Expo organization, and the code stay in your name. If you bring the work in-house later, nothing needs to be moved.
Honest about React Native's limits
Graphics-heavy apps and some hardware features run better fully native. If your app is one of them, we'll say so on the first call.

Good fit
Product teams already on React
Your web app is built in React and TypeScript, and you want a mobile app your same developers can review and extend.
Owners of an outdated React Native app
Your React Native app is several versions behind, the build breaks on new Xcode releases, and nobody wants to touch the upgrade.
Founders choosing a mobile stack
You're weighing mobile app development with React against other options and want one codebase your future hires can work in.
Companies comparing vendors
You're shortlisting a react native mobile app development company and want to see Expo builds, tests, and code you own.
Teams adding React Native capacity
You need to hire React Native app developers for a deadline your in-house team can't meet alone.
Not a fit
No React on your team
Nobody on your team writes React, and you still want one codebase for both stores. Our Flutter App Development Services page may suit you better.
Design first
You want screens tested with real users before anyone writes code. Our Mobile App Design Services page handles that stage first.
Budget under $1,150
Your budget is under $1,150, or a mobile website would serve your users well. If a website is enough, we'll tell you before we quote.
React website, not an app
You need a React website or web app, not a phone app. Our Web Application Development Services page covers React web apps.

Frequently Asked Questions
Straight answers on React Native costs, who uses it, Android builds, and choosing a React Native team.

React Native app development at DeveloperLook starts at $1,150 for an Expo build of your core flow plus a code-sharing plan. A full app on both stores with sign-in, push, and EAS updates starts at $4,500. Teams sharing a monorepo with their React web app, or needing payments and native modules, start at $8,700. Store fees are billed to you directly.
React Native cuts cost by letting one team ship iOS and Android from one codebase, and by reusing skills your React developers already have. Types, validation, and API code can be shared with your web app. Savings shrink when an app needs many custom native modules, so we check your feature list before promising any.
React Native app development is building iOS and Android apps with React and TypeScript that render real native components, not a web page. React Native was created at Meta and is open source. Most new projects use Expo, the framework React Native's own docs recommend, for builds, routing, and native modules. The app installs from the App Store and Google Play like any other.
Yes, React Native is widely used for production mobile apps. React Native's showcase lists apps from Meta, Microsoft, Amazon, and Shopify, and Shopify says all of its mobile apps are built with it. It suits business apps, marketplaces, and internal tools especially well. Teams usually pick it when they already work in React on the web.
Partly: React Native came from Meta, and its showcase lists the Facebook app on iOS and Android among Meta's React Native apps. Marketplace and Ads Manager are named as React Native products too. Large apps often combine React Native screens with native code, the same approach we use to add React Native features to an existing native app.
Yes, React Native is good for most business apps, especially when your team already knows React. It renders native components, so lists, gestures, and text input feel right on each platform. Since version 0.76, the New Architecture is on by default, which speeds up communication with native code. Graphics-heavy games are still better served by a game engine.
It's easier if your developers know React and TypeScript, because components, state, and tooling work the same way. React Native mobile development still has its own rules: navigation, permissions, store signing, and device testing. Expo removes much of the setup, so a React developer can run the app on a phone quickly. Features beyond Expo's modules need Swift or Kotlin knowledge.
Yes, React Native builds full Android apps, and the same codebase produces the iOS version too. Your app ships to Google Play as a normal Android App Bundle, with native Android components on screen. Android-specific code, like a Kotlin module for a device feature, sits alongside the shared TypeScript. Google Play's target API rules apply just as they do to native apps.
Choose React Native when your team works in React, you need iOS and Android together, and you want to share code with a web app. Small JavaScript fixes can also reach users through over-the-air updates between store releases, within store rules. If nobody on your team uses React, another cross-platform option may fit better, and graphics-heavy apps suit native code.
Companies that specialize in React Native app development show apps live in both stores, recent Expo and EAS work, and Swift or Kotlin native modules. DeveloperLook is one of them, but judge every name on your shortlist by the same proof. Ask whether they have upgraded apps across React Native versions, and who owns the Expo organization afterward.
