When you want one app, not two

If you need an app on iPhone and Android and don't want to build and maintain it twice, Flutter is often the answer. We'll build it, or take over the one you have.

  • You need an app on iPhone and Android, and the budget doesn't stretch to two.

  • Your Flutter app was built by someone else, and nobody in-house can maintain it.

  • Your app needs to look exactly the same on every device, down to the brand details.

  • A new iOS or Android release broke your app, or the stores now block updates until it's fixed.

An open-source toolkit from Google for building iOS, Android, web and desktop apps from one codebase, written in Dart.

Product teams who want one app on iPhone and Android without building it twice, from start-ups to large brands.

  1. Dart

    The programming language Flutter apps are written in.

  2. Widgets

    Ready-made interface parts, in Android and iOS styles, that look the same on every device.

  3. Hot reload

    Changes show in the running app in seconds, which speeds up design and testing.

  4. Packages

    Thousands of add-ons on pub.dev for payments, maps, sign-in and more.

  5. Firebase

    Google's back-end services that pair with Flutter: sign-in, data, push notifications and crash reports.

  6. Web and desktop

    The same code can also run in a browser or on a computer, where that makes sense.

  1. Takeovers

    We review an existing Flutter app, fix what's broken and take over the updates.

  2. Connected to your systems

    Apps that share data with your website, CRM and back end.

  3. Store releases and updates

    App Store and Google Play releases, and yearly updates for new OS versions and store rules.

The things people usually ask

Plain answers on how Flutter works, what it costs and what we need from you. Anything else, just ask.

Flutter or React Native?

Both build iPhone and Android apps from one codebase. React Native suits teams who already work in React, and uses each platform's own interface parts. Flutter draws its own interface, so the app looks identical on every device. We'll recommend one based on your team and what the app needs to do.

Does a Flutter app feel like a proper app?

Yes. Flutter compiles to native code and draws its own interface, so apps are fast and look the same on every device. Platform touches, such as iOS navigation patterns, can be added where they matter.

Can Flutter use the camera, location and notifications?

Yes, through plugins. Where one doesn't exist, we write a small piece of platform code for that feature.

Can you take over our existing Flutter app?

Yes. We start with a review of the code, the packages and the store accounts, then agree what we'll look after.

  • CRM, marketing automation and sales tools in one platform.

  • A structured content platform: one source of content for websites, apps and everything else.

  • Ecommerce software for personalised marketing, product search and content.

  • Behaviour analytics: recordings, heatmaps, funnels and friction scores.

  • A visual website platform marketing teams can run themselves.

  • The company behind Claude.

  • Google Analytics, Tag Manager, Ads and Search Console.

  • Amazon's cloud: hosting, databases and AI models for web products.

  • An open-source CMS where editors change content on the page itself.

  • An open-source CMS behind a large share of the web.

  • An open-source PHP framework for web apps and platforms.

  • An open-source PHP framework for complex, long-lived web applications.

  • A JavaScript framework for building fast, interactive front ends.

  • A JavaScript library for building user interfaces.

  • React for iPhone and Android apps, from one codebase.
