Cross-Platform Development Without Compromises

Flutter combines the best qualities of native apps with the efficiency of cross-platform development.

Having two separate apps built for Android and iOS means double development time, double costs and double maintenance. For many organisations, that is not efficient — especially if you want to scale quickly or your budget is limited. Flutter offers the solution: one codebase that runs on both platforms with performance that does not lag behind native apps.

Flutter, developed by Google, has grown into one of the most widely used frameworks for mobile applications. The framework delivers beautiful interfaces with fluid animations, supports hardware-level functionality and is used by companies like BMW, Alibaba and Google itself. It is not a compromise — it is a smart choice.

We build Flutter apps that look and feel like native applications. Your users will not notice the difference — except that you go live faster and pay less. From concept to publication in both app stores: we take care of the entire process.

  • One codebase for both Android and iOS
  • Native performance with fluid 60fps animations
  • Hot reload for faster development and testing
  • Extensive widget library for consistent design
  • Publication in both App Store and Google Play Store

Why Choose Flutter

The advantages that make Flutter the smartest choice for many organisations.

Flutter offers a number of unique advantages that set the framework apart from other cross-platform solutions. First, Flutter delivers native performance. Unlike older cross-platform technologies, Flutter renders directly to the screen without bridging to native components. The result: fluid animations and fast interactions that do not lag behind Kotlin or Swift.

Second, Flutter offers a rich widget library. Every button, menu and animation is pre-built and fully customisable. This significantly speeds up development and ensures a consistent design on both platforms. Your app looks identical on Android and iOS, with respect for platform conventions where needed.

Third, Flutter is actively maintained by Google and a growing open-source community. The framework is regularly updated with new features, security patches and performance improvements. You build on a foundation that will not become outdated quickly.

  • Up to 40% lower development costs compared to native
  • Identical user experience on Android and iOS
  • Faster time-to-market through shared codebase
  • Actively maintained by Google and the community
  • Support for camera, GPS, Bluetooth and more

What Flutter Apps Can Do

Flutter is suitable for a wide range of applications — from consumer apps to business tools.

How We Build a Flutter App

A proven process from concept to publication — for both Android and iOS.

01

Introduction & Analysis

We discuss your objectives, target audience and desired features. We analyse whether Flutter is the right choice for your project.

02

Project Plan

We translate the analysis into a concrete plan with features, architecture, timeline and clear deliverables. You know exactly what to expect.

03

UX Design & Prototyping

We create the user flow and visual design. You see and feel how the app works before we write a single line of code.

04

Flutter Development

Our development team builds the app with Flutter and Dart. Thanks to hot reload, we can iterate quickly and you see results regularly.

05

Backend & Integrations

We build the server-side infrastructure and connect your existing systems such as CRM, ERP or databases via API integrations.

06

Testing & Quality Assurance

We test the app thoroughly on both Android and iOS, across different screen sizes and network conditions. Bugs are identified and resolved.

07

Publication & Launch

We handle publication in both the Apple App Store and Google Play Store. Including optimisation, screenshots and all required assets.

08

Aftercare & Further Development

Even after launch, we remain available for maintenance, updates and new features. We monitor performance and advise on improvements.

Why Choose Speedy Systems

Frequently Asked Questions About Flutter Apps

Answers to the questions we receive most often.

What is the difference between Flutter and native development?

Flutter is a cross-platform framework by Google that builds apps for both Android and iOS with one codebase. Native development (Kotlin for Android, Swift for iOS) builds separate apps per platform. Flutter offers faster development and lower costs, native offers maximum performance and access to the latest platform-specific features.

Does a Flutter app perform as well as a native app?

Yes, in most cases it does. Flutter renders directly to the screen with its own rendering engine, which provides fluid 60fps animations and fast interactions. For most business applications, e-commerce apps and customer portals, the performance difference is not noticeable to users.

How long does it take to build a Flutter app?

A standard Flutter app is delivered within 8 to 12 weeks. Because we use one codebase for both platforms, this is significantly faster than developing two separate native apps. More complex applications with extensive backend systems take 14 to 20 weeks.

What does a Flutter app cost?

A Flutter app starts from €10,000. This includes design, development for both platforms, backend and publication in the app stores. The costs are lower than two separate native apps because we share one codebase. We always provide a custom quote.

Can I switch to native development later?

Absolutely. Flutter apps can always be supplemented with native modules if you need specific functionality that is only available natively. Your app remains cross-platform but can use native components where necessary.

Will my Flutter app be published in both app stores?

Yes. We handle the full publication in both the Apple App Store and the Google Play Store. Including App Store optimisation, screenshots, descriptions and all technical requirements. You do not have to worry about a thing.
