React Native App Development Company for iOS and Android
React Native app development services that put one codebase on both stores: UX and UI designed in-house, apps built with React Native, Expo and TypeScript, native modules where they are needed, and App Store and Google Play releases handled end to end.
What We Serve
React Native Apps That Feel Native on Both Platforms
Building the same app twice, once in Swift and once in Kotlin, doubles the cost of every feature and every bug. React Native removes most of that duplication: one TypeScript codebase, real native components, and a single team shipping to iOS and Android together. The catch is that a cross-platform app only feels right when someone cares about the details: navigation that behaves the way each platform expects, lists that scroll smoothly on a mid-range Android phone, and startup time measured on real devices. As a React Native app development company with designers and engineers in one studio, we design the screens, build them with Expo and the New Architecture, write native modules when a feature needs them, and take the app through store review. AI tools draft components and tests; senior engineers review every pull request.
Our Approach
Design the Flows, Build on Expo, Test on Real Devices
Every app starts with the journeys that matter: sign-up, the core action, payment, and what happens offline. Those are designed and prototyped before a line of code. We build on Expo with TypeScript, file-based routing and a shared component library, so new screens come together quickly and stay consistent. Performance is checked on real low and mid-range phones, not only simulators. Each build runs automated tests and goes to TestFlight and Play testing tracks for your team to try. Over-the-air updates let fixes reach users without waiting for a store release where the store rules allow it.
What Is React Native App Development?
React Native app development is building iOS and Android apps from one React and TypeScript codebase. The interface is drawn with each platform’s own native components, so the app looks and behaves like a native app while most of the code is shared.
One shared codebase
Features built once and released on both platforms.
Native components
Real platform views, gestures and navigation.
Native modules when needed
Swift and Kotlin for cameras, payments and device features.
Fast release cycle
Automated builds, store submissions and over-the-air updates.
At Devoq Design, React Native app development means designed, typed and tested apps delivered about 5x faster, with senior engineers reviewing every change.
Why React Native App Development Makes Sense
For most products, the question is not whether an app can be native, but whether two separate teams are worth paying for. React Native usually answers that.
One Team, Two Stores
iOS and Android ship together from the same code.
Lower Cost per Feature
Most logic and interface code is written once.
Shared Web Skills
React and TypeScript knowledge carries across web and mobile.
Native Feel
Platform components, gestures and animations at 60 frames per second.
Quick Fixes
Over-the-air updates for urgent JavaScript changes.
A Mature Ecosystem
Proven libraries for payments, maps, push and offline data.

Frequently Asked Questions
What does a React Native app development company do?
It designs and builds iOS and Android apps from one React Native codebase: UX and UI design, app development in TypeScript, native modules, backend and API integration, testing on real devices, and App Store and Google Play submission. Devoq Design delivers design and development as one team.
Is React Native good enough compared with fully native apps?
For most business, consumer and SaaS apps, yes. React Native renders real native components, and the current architecture removes most of the old performance gap. Apps that are mostly heavy 3D graphics or deep device-level work can still be better served by Swift or Kotlin, and we will say so if that is your case.
Should we choose React Native or Flutter?
Both ship quality apps. React Native fits best when your team or your web product already uses React and TypeScript, because skills and some code carry over. Flutter fits teams that want one rendering engine and a pixel-identical interface on every platform. We build with both and recommend one after looking at your product and team.
How much does React Native app development cost?
It depends on the number of screens and user roles, integrations such as payments or maps, offline requirements, the backend, and whether design is included. After a short discovery call we scope a fixed price for a defined release or a monthly retainer for ongoing development.
Can you take over or upgrade an existing React Native app?
Yes. We audit the codebase, dependencies, performance and release setup first, then agree a plan: upgrade the React Native version, move to Expo or the New Architecture where it helps, add tests around the risky parts and resume feature work. A trial sprint comes first so you can judge the fit.
How is this about 5x faster than a traditional agency?
Four things add up: several AI-drafted options at once instead of one at a time, generated boilerplate and tests instead of hand-written setup, reusable component libraries instead of page-by-page builds, and automated checks on every change instead of a manual pass at the end. Review time stays the same; waiting time disappears.
Is AI-assisted work good enough, and is it safe?
AI never ships anything on its own. A senior lead reviews every design and every code change, automated tests and accessibility checks run on each one, and the code is plain TypeScript in your own repository. We do not send your customer data to AI tools without a written agreement.
Who owns the code, the design files and the accounts?
You do, from the first week. Figma, GitHub, CMS and hosting accounts are created under your company, and the contract assigns the IP to you. There is nothing to hand back at the end because it was always yours.
How do you charge: fixed price, monthly retainer or dedicated team?
All three, depending on the shape of the work. A fixed price when the scope is clear, a monthly retainer when the work keeps evolving, and a dedicated designer or engineer pair when you want capacity inside your own team. We recommend one after a short discovery call.
Do you work with companies in the US, UK, Canada or Australia?
Yes, most of our clients are there. Devoq Design has teams in India, Canada and the US, so every project has overlapping hours for reviews and stand-ups. Everything else runs async with recorded walkthroughs, decision logs and written updates in your Slack or Teams.
How do we get started?
Book a 30-minute call or send a short brief. We come back within a few working days with a scope, a plan and a price. Work starts after an NDA and IP assignment are signed and your accounts are set up.
