Where can I get one Flutter app development?
The best way to build a Flutter app is with an agency that specialises in Flutter and has its own development team. One shared codebase creates native apps for iOS and Android, optionally with web support, including backend, interfaces and store release. CodeGuides develops Flutter apps in-house in Germany and can also take care of maintenance, monitoring and further development after launch. For general agency selection, the app agency page provides more context.
Flutter App development: When Flutter dies is the best choice
Flutter is ideal if you use iOS and Android of a code base want to operate and place value on performance, UI quality and predictable maintenance.
Many teams are looking for Flutter app development, because two native apps quickly lead to double effort. Flutter offers a common codebase for iOS and Android and optionally web.
If you have a Have the Flutter app programmed, three things should be right from the start: architecture, release process and measurability. This is exactly where we come in, so that your app not only starts, but can also be reliably developed further in the long term.
Im Initial consultation we clarify your use case, integrations, offline requirements, role model and security. If Flutter isn't optimal, we'll say so openly and recommend alternatives.
If you generally want to develop an app: App development. If you are looking for an app agency for companies: App agency. If you need additional capacity: Book a development team. If you would like a clear roadmap and support: Advice and support.

Reference: Findeling migration and modernization to the Flutter platform
A customer previously operated four separate apps (iOS and Android for private and business customers). We transferred the applications to a common Flutter codebase, including backend modernization, cloud and operations.
- Reduction of four codebases to one Flutter codebase
- Significantly lower maintenance effort and faster releases
- Consistent UI for private and business customers
- Backend modernization including API layer and cloud deployment
Result: around 75 percent less maintenance effort, higher release frequency and a stable basis for further expansion stages.
Findeling is the local super app for Europe, with many different functions: news, events, products, services, offers, pinboard and much more.

Flutter app costs: typical corridors and most important cost drivers
Many searches revolve around Flutter costs. Here you will find realistic corridors and the factors that really influence Flutter app costs.
Typical cost corridors
| Variant | Description | Corridor |
|---|---|---|
| MVP | Core functions, few screens, simple roles, pilot project. | ca. 10.000-30.000 € |
| Business app | Login, rights, integrations, push, monitoring, multiple modules. | ca. 40.000-90.000 € |
| Platform and Enterprise | Complex workflows, role models, dashboards, operations. | from €90,000 |
When you have specific requirements, a quick clarification is often faster than long estimates. Book initial consultation or directly App cost calculator.

Frequently asked questions: Flutter agency, Flutter app costs and Flutter app development
How much does it cost to have a Flutter app developed?
Flutter app costs depend on feature scope, integrations and quality requirements. An MVP is often between EUR 10,000 and 30,000. Business apps with roles, interfaces and monitoring are often between EUR 40,000 and 90,000. You can get an initial estimate via the configurator or in the first consultation.
Is Flutter the right choice for a business app?
Yes, Flutter is very suitable for business apps when iOS and Android should be covered in parallel and a consistent UI matters. Architecture, releases and clean integrations are decisive. That is exactly what we clarify in the first consultation.
Can I migrate an existing app to Flutter?
Yes. We analyse the codebase, dependencies and risks, then plan the migration step by step or as a relaunch. The goal is a maintainable Flutter codebase with stable releases.
Does CodeGuides also provide Flutter developers to extend a team?
Yes. If you need capacity at short notice, you can book a development team. Our Flutter developers onboard in a structured way, deliver results quickly and keep code quality and processes stable.
Do you develop in-house in Germany?
Yes. We work 100 percent in-house in Germany, without nearshoring or offshoring. That means direct communication, clear responsibility and predictable quality.
Do you take over operations and further development after launch?
Yes. If desired, we take care of maintenance, updates, security patches, monitoring and further development. This keeps your Flutter app stable and scalable long term.
What is a Flutter app?
Flutter is Google's open-source framework for native cross-platform apps. A Flutter app runs natively on iOS, Android, web and desktop from a single codebase. It compiles to native ARM code without a JavaScript bridge and delivers performance comparable to Swift or Kotlin apps. For companies this means one development team, one codebase and one maintenance effort for all platforms.
When is a Flutter agency the right choice?
A Flutter agency makes sense when you want to cover iOS and Android from one shared codebase, need a consistent UI and want to bundle maintenance and operations. For purely platform-specific requirements with deep native hardware integration, native development may be more suitable. For general agency selection, the app agency page provides more context.
Which apps is Flutter suitable for?
Flutter is especially suitable for business and B2B apps with forms, lists, roles, dashboards and backend connections that should run consistently on iOS and Android. It is also strong for MVPs and apps with frequent releases because one codebase is maintained. For highly graphics-heavy games or very specific hardware use, an individual assessment is worthwhile.
Does CodeGuides develop Flutter apps for iOS and Android?
Yes. CodeGuides develops Flutter apps for iOS and Android from one shared codebase, including backend, interfaces, store release and optional operations and further development. Development is handled in-house in Germany.
How much does Flutter cost compared with native development?
Flutter itself is free. The decisive saving is in development: one codebase for iOS and Android instead of two separate teams typically reduces development, testing and maintenance by 30 to 50 percent. If you need iOS and Android, Flutter is significantly more cost-efficient than two native apps while keeping native performance on both platforms.
