React Native & Flutter development
One codebase, two app stores. React Native and Flutter let us ship iOS and Android together, and we write native Swift or Kotlin modules only where hardware or performance demands it.
In plain words
What is React Native & Flutter?
Think of writing one book and printing it in two languages at once. With React Native or Flutter we write the app once, and it becomes both an iPhone app and an Android app.
Cross-platform apps share most of their code between iOS and Android. Where the phone needs something special, like the camera or Bluetooth, we add small native pieces.
What this means for your business
- Launch on the App Store and Google Play together instead of building two apps
- Fixes and new features reach both platforms at the same time
- The app can share accounts and data with your website through the same backend
How it works
How a cross-platform app works
Each box is one part of the system. The arrows show how information moves between them.
What happens when a customer books a service
- 1
The customer picks a slot in the app on their phone.
- 2
The app sends the booking to the backend, which checks the slot is still free.
- 3
The booking is saved, and Firebase sends a push notification to confirm it.
- 4
Your staff see the new booking on their dashboard or staff app.
For technical readers
Why we use React Native & Flutter
One codebase, two stores. Cross-platform mobile apps with native modules where performance demands them.
A shared codebase halves delivery time, and we drop to native modules only where hardware or performance demands it.
The tools, explained
- React Native
- Cross-platform apps with React and JavaScript
- Flutter
- Cross-platform apps with consistent custom UI
- Expo
- Faster React Native builds, updates and releases
- Dart
- Language used by Flutter
- Swift
- Native iOS modules when needed
- Kotlin
- Native Android modules when needed
- Firebase
- Authentication, push notifications and analytics
What we build with React Native & Flutter
- 01
Consumer apps launching on both stores
Sign-up, payments, maps and push notifications on iOS and Android from the first release.
- 02
Field and delivery staff applications
Offline-friendly apps for orders, check-ins, photos and signatures in the field.
- 03
Companion apps for web platforms
Mobile access to an existing web product, sharing the same backend and accounts.
Is React Native & Flutter right for your product?
We recommend a stack in writing during discovery, with the trade-offs stated. These are the signals we look for.
A good fit when
- You need iOS and Android without paying for two separate apps
- Your app is mostly screens, forms, lists, maps and payments
- You already have a React web team (React Native) or want pixel-consistent UI (Flutter)
Probably not the best choice for
- Graphics-heavy games or AR, where fully native or a game engine fits better
- Apps that depend on brand-new platform features on day one

React Native & Flutter: frequently asked questions
Should I choose Flutter or React Native?
React Native suits teams that already use React and want to share code with a web app. Flutter suits products that want a highly consistent custom design across devices. Both ship to iOS and Android from one codebase.
Will a cross-platform app feel native?
For most business and consumer apps, yes. Both frameworks render smooth native-feeling screens, and we add native modules for camera, Bluetooth or performance-critical parts when needed.
Do you publish the app to the App Store and Play Store?
Yes. We handle builds, store listings, review submissions and release updates, under your developer accounts so you keep ownership.
