React Native development

React Native app development

With React Native you launch on iOS and Android from a single TypeScript codebase, with a native look and feel. ATA Technology builds, publishes and maintains React Native apps, and can share logic with your React web application.

01What we do with React Native

  • 01

    New apps

    From prototype to App Store and Google Play release with React Native and Expo.

  • 02

    Web + mobile in one stack

    Sharing business logic, types and API clients between your React web app and mobile app.

  • 03

    Native modules

    Swift and Kotlin modules when an app needs device features beyond the standard toolkit.

  • 04

    Upgrades & rescue

    Upgrading outdated React Native projects, improving performance and fixing unstable builds.

  • 05

    Over-the-air updates

    Shipping fixes quickly with EAS Update, within the App Store and Google Play rules.

02Why React Native

React Native is used by many of the world's largest apps. It shortens time to market, reduces maintenance to one codebase and lets web and mobile teams share knowledge. With the new architecture and Expo, performance and developer experience are better than ever.

03What you get

  • TypeScript codebase

    One typed codebase for iOS and Android, with a clear structure and shared components.

  • Expo and EAS setup

    Configured builds, signing and environments, so every release is repeatable.

  • Shared logic with your web app

    Types, validation and API clients shared with your React web app where it makes sense.

  • Native modules when needed

    Swift and Kotlin code for device features that existing libraries do not cover.

  • Over-the-air update channel

    An EAS Update setup for quick JavaScript fixes, within App Store and Google Play rules.

  • Code review and upgrade plan

    For existing apps: an assessment of dependencies, architecture and risks, with a prioritised plan.

04Who it's for

  • 01

    A React web team going mobile

    A company with a React or TypeScript web product wants a mobile app without building a separate native team.

  • 02

    Launching on both platforms at once

    A startup wants to reach iPhone and Android users at the same time from a single codebase.

  • 03

    An app stuck on an old version

    An existing React Native app can no longer be upgraded easily, builds fail or performance has slipped.

  • 04

    A product that changes often

    Frequent changes call for fast iterations and the ability to ship small fixes without a full store release every time.

05How we work

  1. Assess the starting point

    For a new app we check what can be reused from your web stack; for an existing app we review the code and dependencies.

  2. Lay the foundation

    Expo, TypeScript, navigation, state management and EAS builds are set up before feature work begins.

  3. Build on shared components

    Screens are built from one component library, so iOS and Android stay consistent.

  4. Go native where it pays off

    Performance-critical parts and missing device features get native Swift or Kotlin modules.

  5. Release through channels

    Separate internal, beta and production channels for builds and OTA updates keep every release under control.

07Our standards

  • 01

    Native feel

    Platform-appropriate navigation, gestures and animations that run smoothly on the native side.

  • 02

    Type safety end to end

    Typed API contracts between app and backend catch breaking changes before release.

  • 03

    Current dependencies

    Regular upgrades of React Native, Expo and libraries, so the app does not fall behind.

  • 04

    Crash and error monitoring

    Crash reporting and error tracking on every build, so issues surface before users report them.

09Frequently asked questions

Is React Native good for business apps?

Yes. For most business, commerce and service apps React Native offers near-native performance with a single codebase for iOS and Android, which lowers development and maintenance costs.

Can you take over an existing React Native app?

Yes. We start with a code review, upgrade dependencies where needed and then continue development and maintenance.

React Native or Flutter?

Both are solid. React Native is a natural fit if you already use React or TypeScript on the web; Flutter can be a good choice for highly custom UI. We help you choose.

Does a React Native app feel native?

Yes. React Native renders real native components, and with the new architecture animations and gestures run smoothly on both platforms.

Can we share code with our website?

Yes. Business logic, types, validation and API clients can be shared with a React or Next.js web app; the interface itself is usually adapted per platform.

Do the app stores allow over-the-air updates?

Yes, for JavaScript and asset changes that do not change the purpose of the app. New native functionality still goes through a regular store release.
