Custom mobile app development studio in Spain
iOS and Android apps from one codebase in React Native and Expo. From first prototype to the stores, with back-end, payments and hardware integrations when needed.
We build apps people use every day: the one that runs an autopilot for boats, a hotel's digital front desk, or a dealership's sales tool.
We use React Native and Expo to ship iOS, Android and, when it helps, web from one codebase. It costs less to build and maintain without giving up a native feel.
- React Native and Expo
- Back-end, API and database
- Bluetooth, OTA and hardware
- Payments and subscriptions
- App Store and Google Play release

How much does an app cost?
It depends on the app, so we go through it with you on a 30-minute call and suggest how to build it. Book it from «Book a call».
How long does it take?
An MVP takes 6–10 weeks. We work in two-week sprints and you see progress every week.
Why React Native instead of native?
One codebase gives you iOS and Android, a smaller team and simultaneous releases. When something needs native code, we write it.
