Rebel App Studio was born, to focus solely on Flutter consulting and community work

What is Flutter?

Flutter is an open source framework by Google for building beautiful, natively compiled, multi-platform applications from a single codebase.

It makes you release faster than anything else. It provides the best performance. It does not break with new OS releases.

World leaders in Flutter

More experience than anyone: Flutter consulting since 2017.

Expertise you can’t find elsewhere: Developing Flutter with Google.

Pushing the boundaries: we find the limitations of Flutter and push through them. Even if we have to change Flutter itself.

Powered by Codemate

Powered by Codemate: a Nordic creative tech agency.

Making apps long before Flutter: We’ve used everything.

100 people with 15 years’ experience and over 700 projects. Awesome customers: Netflix, Taco Bell, Ericsson.

    Fast development

    Flutter’s hot reload helps you quickly and easily experiment, build UIs, add features, and fix bugs faster. Experience sub-second reload times without losing state on emulators, simulators, and hardware.

    Expressive, beautiful UIs

    Delight your users with Flutter’s built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness.

    Native Performance
