Cross-platform mobile app development

We build iOS and Android apps from a single codebase with Flutter or React Native, so you launch on both platforms without paying for two separate apps.

A mobile app is only as good as the API behind it. Because our team also builds backends, the app and its API are planned together, including offline behaviour and how data syncs when the connection returns.

FAQ

Common questions.

Do you use Flutter or React Native?

Both. Flutter is our mobile engineer’s main toolkit, and React Native suits teams that already work in React and TypeScript. We recommend one based on your product and who will maintain it.

Can you build the backend for the app too?

Yes. The same team builds the API, database and authentication, so the app and its backend are designed together.
