_Why Flutter
Flutter is one of the most popular app frameworks. For these 6 reasons.
Does your company want and need to accelerate its digital transformation in order to remain competitive? Apps often play a key role in this. Flutter is a popular choice as a technology framework because it enables the development of apps that deliver a first-class user experience while being easy on your budget.
Fast development
The hot reload feature and access to numerous libraries and tools speed up the development of your Flutter app many times over compared to traditional methods.
3
Near-Native Performance
Flutter apps can keep up with native apps in terms of performance in most use cases. The biggest difference to these: They are created much faster than their native relatives.
4
Cost savings
Flutter’s framework enables you to realise high-performance apps with a first-class user experience – in a cost-efficient way. The short development time ensures a fast ROI.
5
Intuitive Usability
Flutter is for those who want a sophisticated UI. Our developers have access to a wide range of widgets and can build your interactive app for Android and iOS with a native look and feel.
6
Strong community
The technology is being continuously developed by an enthusiastic community of developers, supported by Google, and brought up to the latest technological standards.

_Frequently asked questions
FAQs
What is Flutter?
Flutter is an open source technology from Google for the development of platform-independent mobile applications. With the help of the framework, apps can be created for any platform from a single code base - for Android, iOS, desktop, embedded or web. This significantly shortens your development time. A major advantage for your company if you rely on hybrid apps and want to be accessible to your customers on all digital channels. You save significantly on development costs without having to compromise on the functionality or quality of the app. Flutter apps are based on the DART programming language and impress with their fast performance and modern user experience. The app technology is therefore just as popular with established SMEs and corporations looking to accelerate their digitalisation as it is with start-ups.
What is the difference between Flutter and React Native?
Flutter and React Native are both leading technologies for the development of cross-platform apps. However, Flutter is superior to React in three points in particular:
- Programming language: unlike React Native, which relies on JavaScript, Flutter uses DART as its programming language, which optimises performance and simplifies development for hybrid apps.
- Low code: Flutter also follows an "everything is a widget" philosophy: layouts, texts, icons - everything can be designed and changed using widgets. Fast and low-code.
- Compilation: Unlike React Native, Flutter apps do not require a JavaScript bridge to run on all end devices. The app is compiled on the end device before your Flutter app is installed. Changes to the code are immediately visible without recompiling. As a Flutter agency, we guarantee you strong performance on mobile, website and desktop.
For which apps is development with Flutter particularly suitable?
Apps for multiple platforms: If your organisation wants to publish an app for not just one, but multiple platforms, Flutter is the right choice. The development framework allows you to quickly create apps for different platforms from one code base without compromising on design or performance.
Limited budget: If you only have a limited budget for your app development, Flutter is the technology of choice. Not only Flutter's one-code-base approach, but also the use of comprehensive widget libraries can significantly reduce the development time of your new app. This also reduces your project costs and makes it easier for you to achieve a quick return on investment.
Tight timeline: In many industries and use cases, it is important to realise an idea quickly in order to secure significant advantages on the market. Even if your budget is not a limiting factor, Flutter is the technology of choice in such cases due to its short development times.
Customised functions: Do you want your app to stand out creatively from the crowd and not just offer basic functions? Flutter works with many widgets, but still offers a high degree of flexibility in the design of apps. Even complex functions and individual interactive user interfaces can be realised with manageable effort.
High performance and stability: As Flutter apps are compiled directly in the code of the target platform, your apps are less prone to errors and offer outstanding performance that is comparable to native apps. You do not need a browser or runtime module, which has a very positive effect on the performance and look and feel of your applications.
How much does it cost to develop an app with Flutter and how long does it take?
There is no general answer to this question. Of course, how complex the programming is depends very much on the individual requirements of your app. Nevertheless, to give you an initial idea of the time and costs involved: Experience has shown that a simple app with Flutter can be published after just a few weeks. To realise a high-performance Flutter app, you need to reckon with an investment of 50k euros for a simple application. As a Flutter agency, we unfortunately have to turn down cheaper and smaller projects for economic reasons. Depending on the complexity of the app, a higher budget may be required.
Which platforms are supported by Flutter?
Flutter supports the development of apps for the iOS and Android mobile operating systems. As a Flutter agency, we can also create web apps and apps for desktop and IoT devices for you, which further expands the possible uses of the framework.
How well does a Flutter app scale and how does its performance compare to native apps?
Flutter apps can be easily scaled and, as already frequently mentioned, have a performance that can keep up with native apps. This is due to some special features of their architecture.
- Performance: Flutter apps, for example, are compiled directly in the native code of the target platform. The framework uses its own rendering engine, Skia, so that even complex UIs can be rendered at high frame rates and even complex graphics run smoothly in your app. However, native app development may still be preferable for some interactive games.
- Scaling: As the code base for your apps is the same on all platforms, your change requests and extensions can be implemented quickly and apps can be published on new platforms without much additional effort. What's more, the community regularly releases new tools and integrations that make it easier for our developers to scale their apps.
How secure is a Flutter app?
Flutter offers many different security features as standard. However, the security of your Flutter app depends largely on the way it is developed and the security practices that are built in. As a Flutter agency, we think about your security from the start and use automated and manual testing to ensure it at every stage of our development until release. After release, you should install Flutter (security) updates promptly to avoid creating new and avoidable vulnerabilities that cybercriminals could exploit for their own purposes.
How can an appealing user experience be achieved with Flutter?
One of Flutter's strengths is that the framework makes it very easy to design attractive, interactive user interfaces. An extensive collection of ready-made widgets is available for this purpose, which can be used to realise UI elements consistently for all platforms. The platform also facilitates the implementation of complex animations and transitions, which can contribute to a contemporary look and feel for your apps.
To ensure that your users can quickly find their way around your app, our developers must adhere to the design guidelines of the respective platform: Material Design applies for Android and Cupertino for iOS. With Flutter, all design patterns can be adhered to. In addition, the platform offers various navigation patterns that can be tailored to the needs of the individual target group to ensure intuitive and efficient user guidance.
