Cross-platform app development with Flutter
From the first idea through UI/UX and development to the app store launch, we support your project end-to-end.
One codebase for iOS, Android and the web: as a Flutter agency, we build high-performance apps with a native look and feel – faster and more cost-effective than developing everything twice.
Why Flutter?
Flutter is a powerful open-source framework by Google that lets us build apps for iOS, Android and the web from a single codebase.
Up to 30% lower costs: one codebase instead of two separate native builds – the saved budget goes into features, marketing and growth.
Native performance: Flutter renders the UI with its own rendering engine directly on the GPU – smooth animations and a truly native feel included.
One team, one release: new features ship for iOS and Android at the same time – without double testing and maintenance effort.
Proven in production: from PAGOPACE to the e-prescription app to Piening Connect – many of our production apps run on Flutter.

The advantages of Flutter
Flutter combines the efficiency of cross-platform development with the quality of native apps. These four advantages win our clients over every time:
01
Lower costs & faster time-to-market
One codebase for all platforms cuts development time and costs by up to 30%. Your product reaches the market sooner, and the saved budget goes into growth and features.
02
Native performance
Flutter compiles to native code and renders with its own engine directly on the GPU. The result: smooth animations and short loading times.
03
Flexible UI design
Flutter's widget system implements any design pixel-perfectly – from Material Design to a fully custom brand experience, consistent across all devices.
04
Seamless system integration
Camera, NFC, Bluetooth or native SDKs: through platform channels we reliably integrate any native interface into your Flutter app.
Not sure whether Flutter is the right technology for your project?
In a free initial consultation we will assess together whether Flutter fits your requirements – or whether native development is the better choice.

With Readfy, up to half a million users regularly read over 130,000 ebooks for free. Johnny Bytes took over the apps for iOS and Android from our previous nearshore partner and not only brought them and the backend up to date in a very short time, but also ensured that in-app sales increased by 500%.

PAGOPACE
We were already able to offer our customers good hardware with our payment ring. However, Johnny Bytes helped us to build the perfect complementary software to take our product to the next level. We were kept up to date at every stage of the app development and were able to make requests immediately. With the new app, we can also sell our rings in retail stores, as customers can link their rings directly to their payment card on their cell phone.
