Cross-Platform Development (Flutter, React Native)

One Flutter or React Native codebase for both iOS and Android, reaching both stores faster than two native builds.

Overview

Building two native apps means two codebases, two teams and two sets of bugs. Flutter and React Native let one codebase serve both platforms, which suits most business apps well.

We build cross-platform apps that still feel at home on each platform, test them on real iOS and Android devices and ship them to both stores.

What we do

  • 01

    Choose between Flutter and React Native

  • 02

    Build one shared codebase for iOS and Android

How we work

  1. Step 1

    Scope

    We agree features, platforms and the devices your users have.

  2. Step 2

    Build

    Native or cross-platform development in weekly increments.

  3. Step 3

    Test on real devices

    Every build is tested on physical iOS and Android devices.

  4. Step 4

    Release

    Store submission, launch monitoring and updates.

Who it's for

  • Startups needing iOS and Android on one budget
  • Teams with web React skills moving to mobile
  • Companies maintaining two drifting native apps

What you get

  • A Flutter or React Native app in your repository
  • Real-device testing on both platforms
  • Releases to the App Store and Google Play
  • Automated smoke tests if needed

Questions

Flutter or React Native?+

Both are mature. React Native suits teams with JavaScript skills; Flutter offers consistent UI and strong performance. We'll recommend one for your team.

Will it feel like a native app?+

For most apps, yes. We handle platform differences in navigation, gestures and design where they matter.

How quickly can you start?+

Most engagements start within 5–7 business days of agreeing scope, and urgent work can start within 48 hours.
