Mobile app: native or React Native?
Native or cross-platform mobile development: differences in cost, speed and user experience, and when React Native with Expo is the right choice for iOS and Android.
Mobile app development for iOS and Android
A mobile app has to be fast, reliable and feel like it belongs on the phone. We build apps for iOS and Android from one codebase with React Native and Expo, so you get both platforms for a price closer to one.
Apps we have built include a 76 screen SaaS released on the App Store, a fintech app with biometric sign-in and bank linking, and a marketplace with real-time location tracking.
Camera, location, payments, biometrics, notifications, working offline: there is no feature that cannot be done and no problem that cannot be solved.
What you get
- iOS and Android from one codebase
- One team and one codebase for both platforms, which shortens the build and the maintenance.
- Sign-in and security
- Sign-in with email, social accounts and biometrics (Face ID, fingerprint).
- Payments
- Stripe, including Stripe Connect for marketplaces, and subscriptions.
- Notifications and location
- Push notifications, maps and real-time tracking.
- Store release
- We prepare accounts, certificates and listings and run the App Store and Google Play release.
- Connected to the web
- The same backend and data as a web application or an admin panel.
Who it is for
- Companies that want to offer ordering, booking or a loyalty programme in an app.
- Startups that need an app for iOS and Android at once.
- Companies with field teams that need an app for records, photos and location.
- Owners of an existing web application who also want a mobile version.

How we work
A clear process with short cycles and continuous visibility. One person leads the project from the first call to launch, and AI speeds up development under the review of an experienced engineer.
Discovery
We define goals, scope and priorities. Before work begins, you get a timeline and a price range.
Prototype
We build a clickable prototype to confirm the direction early, while changes are still easy.
Development
We develop in short cycles, with regular releases you can test and review.
Delivery
We launch, hand over the code and documentation, and continue with maintenance and upgrades.
Technologies we use
- App
- React Native, Expo, TypeScript, EAS Build
- Backend
- Supabase, Node.js, Laravel
- Services
- Stripe, Plaid, push notifications, maps
- Delivery
- App Store, Google Play, AWS
- Flexibility
- The technology is chosen to fit the project, not the other way round: Python, PHP, Vue, Angular and more, or whatever you already use.
Questions about mobile apps
How much does a mobile app cost?
Prices start from €1,800, and the hourly rate from €35 per hour. The final amount depends on complexity: the number of screens and features, integrations, design and security. After a short conversation you get a free scope estimate and a price range, with no obligation. Prices are indicative and exclude VAT.
Do I need separate apps for iOS and Android?
Not necessarily. With React Native one codebase runs both platforms, except when a very specific native feature is needed.
Who publishes the app on the App Store and Google Play?
We run the whole process, but the publishing accounts (Apple Developer, Google Play) are opened in your name, so the app stays yours.
How long does it take to build a mobile app?
A simpler app takes a few weeks and a more complex system up to a few months, depending on complexity. We include App Store and Google Play review time in the plan.
Who publishes the app in the stores?
We prepare and publish the app, and it is published under your own developer account, so it stays yours.
Does the app need a backend?
Most apps need a server side for users and data. We build it together with the app, or connect the app to your existing system.
