React Native — mobile apps for iOS and Android

// Who uses it

React Native powers products you use every day.

If React Native is enough for Instagram with hundreds of millions of users, it’s probably enough for your app too.

// Why React Native

Six reasons it’s the safest choice today.

Business reasons first. Technical details below, if you want to look under the hood.

// For business

01

−35% cost

One budget instead of two

A native iOS and Android app is two separate projects: two teams, two codebases, two rounds of testing. React Native is one project that ships to both platforms. In practice, that means 30–40% cost savings versus parallel native development.

02

MVP in 3 weeks

Faster to users

First product versions hit testing and the stores in weeks, not quarters. You can react to market feedback before the competition finishes planning.

03

1 team

Easier maintenance

Bug fixes, feature changes, new releases — one team, one pass. No more juggling schedules between iOS and Android.

04

reuse with web

Code sharing with web

If you already have (or plan) a React web app, a substantial part of the code, logic, and components carries over to mobile. Real savings of time and money — not a marketing slogan. One product, one knowledge base, a consistent experience across all platforms.

05

OTA · minutes

Updates without waiting on the store

Traditional app: you submit a new version, wait a week for App Store review, and pray it doesn’t get rejected. React Native: the fix is in users’ hands in minutes. Found a critical bug at 2:00 PM? It’s fixed for everyone by 2:15. That’s one of React Native’s biggest business advantages.

06

Meta · 2015→

Low technology risk

React Native isn’t an experiment — it’s backed by Meta (Facebook & Instagram), used by half the market, with a mature ecosystem and a community that won’t disappear overnight.

// Honestly

When React Native fits — and when it doesn’t.

We don’t sell every technology for every problem. If React Native doesn’t fit your project, we’ll say so — and propose an alternative.

React Native is a good choice for:

company apps and internal tools (for employees, partners, branches)
first product versions (MVP), when the idea is still searching for its shape
products growing in parallel with a website or web app
consumer apps with a large user base and frequent releases
products with many roles, flows, and admin panels
projects where iteration speed matters more than building native from scratch

Let’s build your idea! →

We advise against React Native if:

Your product is mainly advanced 3D graphics, AR/VR, or real-time rendering. Games, video editors with effects, Snapchat-style AR-filter apps — these are areas where Unity, Unreal, or native with dedicated engines is worth considering.
You need a desktop app, not a mobile one. React Native has desktop ports (React Native for Windows, macOS), but it’s still an area where we recommend deliberately weighing alternatives — including Electron or native.

In those cases we’ll point you to an alternative approach — and help you find the right people.

// Stack

The stack we work with.

Mobile: React Native + TypeScript + Expo

We use proven libraries from the React Native ecosystem, picked to fit the specific project — including Unistyles, React Navigation, Reanimated, Tanstack Query, and others.

Expo is today’s standard for React Native: a coherent, maintained set of modules (Expo SDK) with predictable updates, instead of hand-stitching dozens of packages on incompatible versions. We drop into native code (Swift / Kotlin) only where it’s genuinely needed.

EAS Build gives us repeatable cloud builds, and EAS Update lets us ship a JS fix without App Store and Google Play review. Result: shorter commit → user cycle, faster feedback loop, higher release quality.

Backend, infrastructure, DevOps, and the rest of the technologies we work with are documented in detail here.

// Why it matters

One coherent ecosystem from the database all the way to the screen on your user’s phone. One company, one team, one contract, one point of contact. Less coordination, fewer "not our fault" exchanges, faster decisions.

// Under the hood Technical details — stack, architecture, tooling

▮

TypeScript by default

All code is typed — fewer production bugs, easier onboarding for new people.

▮

New architecture (Fabric + TurboModules)

Real native performance, not a five-year-old compromise.

▮

Native bridge when needed

Where React Native isn’t enough, we write modules in Swift / Kotlin. No fighting the framework.

▮

Expo — a full platform for React Native apps

We work on Expo and its ecosystem, which gives concrete advantages:

EAS Build — cloud iOS builds without needing a Mac on the team.
Expo Updates — instant app updates (OTA) without going through App Store or Google Play review.
Expo Modules — easy authoring of custom native modules when a project calls for it.
Rich SDK — proven, ready-made modules for camera, notifications, biometrics, maps, files, audio, location. We don’t reinvent the wheel.
Active development — Expo is the de facto standard for React Native today, used by most serious teams worldwide.

▮

Mature library ecosystem

We use proven tools picked to project needs — React Navigation, Reanimated, Tanstack Query, Tanstack Form, Tanstack Table, Expo, Zod, Paraglide.js, Ky, FlashList, type-fest, and more.

▮

Observability — Sentry

Production crash reporting mapped back to original source (source maps uploaded during the EAS build). We see real user errors instead of guessing from reports.

Currently — Sentry for crashes — full stack trace, release tagging, build-versioned releases.
Deliberately skipped (for now) — Performance monitoring and release health — added when the project needs them, not by default.

▮

CI/CD and release strategy

A build isn’t the end — what matters is how code reaches users safely.

GitHub Actions — lint, typecheck, and tests on every PR — nothing lands in main without a green gate.
EAS Submit — automated upload to App Store and Google Play, no manual binary handling.
OTA channels (preview / production) — Expo Updates with separated channels — preview for testers, production for users. Promotion is deliberate, not automatic.
Staged rollout — a new version goes to a slice of users first. If crash-free rate drops, we halt the rollout before it reaches everyone.

// FAQ

Frequently asked questions.

Is React Native fast?

Yes — very. Unlike hybrid or WebView solutions, React Native renders real native components directly through iOS and Android. The new architecture (Fabric, TurboModules) eliminates bottlenecks from years past. That’s why React Native powers Discord at hundreds of millions of active users, Instagram, Shopify, and Tesla. Your app will run smoothly and quickly — no compromises.

Will a React Native app ship to App Store and Google Play normally?

Yes. From the stores’ point of view, a React Native app is a regular native app. It goes through the same review process as any other.

What if React Native stops being enough and I want to move to native?

Companies like Tesla use React Native — it’s unlikely to stop meeting your needs. That said, React Native lets you gradually replace individual screens with native (Swift / Kotlin), without rewriting the whole thing. In practice, most companies don’t do this because they don’t need to. But the option is always on the table.

How long does it take to build an app?

We can deliver an MVP in 3 weeks. A full product — typically 4 to 12 weeks, depending on scope. You get an exact timeline after a short discovery phase, once we know the specific scope.

Do I get the source code?

Yes. The code is yours from the first commit. We work in your repository — you have ongoing access.

Do you only do mobile?

No. We also do web (React), backend (Node.js, NestJS, Express), and DevOps and infrastructure. Often the whole product — front, mobile, API, and deployment — is built with us. That simplifies coordination significantly. You can find the full list of technologies and areas we work in here.

How much does it cost?

It depends on the scope. After a short conversation and reviewing the project, we give a range. We don’t work in a "quote without a brief" model — that’s unfair to both sides.

// Comparison

React Native vs…

The three most common questions in a first meeting. Short and to the point.

vs

Flutter

React Native wins

Flutter looks attractive on paper, but in practice React Native has a few concrete advantages that translate into real money and lower project risk:

Language. Flutter uses Dart — a niche language almost no one knows outside Flutter. React Native uses JavaScript/TypeScript — a language millions of developers around the world know. Hiring, team turnover, project continuity — all simpler and cheaper.
Community and ecosystem. React Native has a community several times larger, more ready-made libraries, more solved problems on Stack Overflow and GitHub. Whatever happens in your project, someone’s already solved it.
Code sharing with web. React Native uses the same concepts as React. If you have or plan a web app, a substantial part of your code and logic carries over. Flutter doesn’t give you that — a website is a separate project from scratch.
Platform-native look. Flutter renders everything with its own engine, so apps often look identical on iOS and Android, ignoring both systems’ conventions. Users feel it. React Native uses real native components — an iOS app looks like iOS, an Android one looks like Android.
Risk from Google. Google has a long history of abandoning its own technologies (Angular Dart, Stadia, dozens of products in the Google graveyard). Meta has built React Native into its flagship products, which aren’t going anywhere.
App size. Flutter apps are noticeably heavier — Flutter bundles its own rendering engine into every app.

For most business projects, React Native is simply the safer, more future-proof choice.

vs

Native (Swift + Kotlin)

95% of projects: React Native

Native (Swift for iOS, Kotlin for Android) means, in practice: two teams, two codebases, twice the implementation time, twice the budget, and twice as many opportunities for the apps to drift apart in functionality between platforms.

React Native gives you the same end-user experience — real native components, native performance, access to system features — at a fraction of the cost and time. One team, one codebase, one product consistent across iOS and Android.

In practice: for 95% of business projects, React Native is simply the better call. Less money, less risk, faster to market, easier to maintain.

vs

PWA

React Native for app stores

A PWA is a website pretending to be an app. It runs in the browser, has limited access to device features, handles notifications worse, and isn’t in the stores. React Native is a true native app. If you care about presence in App Store and Google Play — PWA is out. If, on the other hand, a PWA is a deliberate choice for your project — we do those too.
