Six steps to your dream app

Step 1: Defining the idea and goal

Every successful app starts with a clear idea. But this idea should not be created in a vacuum; it should be based on real user needs. That's why the central question is always: What problem should your app solve – and for whom?

A well-thought-out target group analysis helps you design your app to be user-centric right from the start. Create user personas, analyze existing solutions on the market, and ask yourself how your app can be better or simpler. The clearer the objective is formulated—e.g., “increasing efficiency in field service” or “digital customer loyalty for retailers”—the easier it will be to implement later on.

You should also decide early on whether it will be an internal app (e.g., for employees) or a public application. Both variants have very different requirements.

Step 2: Range of functions & app concept

Once the idea and target group have been defined, it is time to define the specific functions. Which features are essential to fulfill the core benefit (must-haves)? And which additional functions would be nice to have, but are not absolutely necessary (nice-to-haves)?

Here, we recommend defining a so-called MVP (minimum viable product)—in other words, the smallest possible version of your app with maximum benefit. At the same time, many project teams create wireframes or simple mockups to develop initial visual concepts. Tools such as Figma or Balsamiq help you to quickly sketch out initial designs in a collaborative manner.

Technical considerations are also important at this stage: Which platforms (iOS, Android, web) should your app run on? Are there interfaces to existing systems? And what special requirements, such as offline functionality or payment integration, are planned?

Step 3: UI/UX design development

The design determines how intuitive and enjoyable your app will be to use later on—and whether users will return at all. Good UI/UX design (user interface/user experience) doesn't think in terms of colors and buttons, but in terms of user experiences.

The focus is on usability: users should understand how the app works right away. Well-designed navigation, consistent interactions, and visual clarity create trust. Performance and loading times are also part of the user experience—an overloaded interface can be just as off-putting as a minimalist design without visual feedback.

Professional design tools such as Figma or Adobe XD are standard in the industry and enable a smooth transition to development – especially with frameworks such as Flutter, which work directly with UI components.

What else should be considered?

One of the most common questions we get asked as an agency is: “How long does app development take—and what costs can we expect?” Our answer: It depends on several factors—but with the right approach, you can keep both your schedule and budget under control.

The duration and cost of a project depend on its scope, functional complexity, platform choice (iOS, Android, web), interface requirements, and design level. A simple MVP (minimum viable product) can often be realized in 8–12 weeks. For larger business applications, we plan between 4 and 9 months on average—each with clearly defined milestones (sprints) and intermediate goals.

Important: In our collaboration, each project is calculated individually – based on a free initial consultation in which we discuss your goals, target groups, and technical requirements. We recommend budget planning including a buffer (10–20%) for later feature requests, market feedback, or expansions.

For efficient project management, we rely on agile methods such as Scrum, Jira, or Kanban, depending on the project goal and team structure. These enable iterative development with maximum flexibility: you remain informed and involved at all times and can provide feedback directly in the next sprints.

Case study: AI-supported trade fair solution for a digitalization startup

An up-and-coming startup in the field of sales digitization approached us with a clear vision: it was looking for an experienced Flutter agency in the region that would be able to quickly develop a powerful, AI-supported trade fair app—including iOS, Android, and web support.

The company supports medium-sized customers in digitizing and automating their sales processes. In addition to strategic consulting, the team relies on intelligent software solutions to increase efficiency, data quality, and scalability in the sales process.

The challenges

The company was looking for an intuitive tool that could structure trade fair contacts and quickly capture and share them across teams. A key challenge was the tight deadline, as investors wanted to see initial results early on, meaning the app had to be completed in just two months. In addition, the AI functions (such as speech recognition, translations, and business card scans) required precise technical implementation within the tight timeframe.

Conclusion

This case study shows how even complex app projects can be implemented quickly and to a high standard of quality — provided that the planning is right and technology, design, and communication are optimally integrated. As a Flutter agency, we were once again able to demonstrate how powerful a modern tech stack can be in the right hands.

App development doesn't have to be a daunting large-scale project. With a clear 6-step plan – from the idea to the concept and design to development, launch, and further development – a vision can be turned into a functioning, user-friendly application.

The key factors here are well-founded objectives, the selection of suitable technologies (e.g. Flutter), realistic time and cost planning, and partnership-based cooperation with an experienced agency.

Whether you're a startup or an established company, listening to user needs early on, remaining flexible, and continuously optimizing your app after launch will give you the best chance of long-term success in the digital market.
