THE AGENCY FOR
APP DEVELOPMENT

Depending on the complexity and scope of features, having an app developed costs between approximately €20,000 for simple apps and over €150,000 for comprehensive platforms. Moderately complex projects typically range from €50,000 to €150,000. We work in clearly defined subprojects to ensure that your investment risk remains manageable at every stage. Thanks to the systematic use of AI throughout the project, we also operate significantly more cost-effectively than traditional agencies.

Depending on the scope, app development takes between 6 weeks and 6 months. An MVP with the most important core features can go live in as little as 3 months, while comprehensive platforms with multiple user roles and interfaces take longer. AI-powered workflows further streamline our design and implementation processes without compromising quality.

At devsuit, your app is developed in clearly definable steps, from concept to finished product. We start with a discovery workshop, clarify goals and requirements, and develop wireframes and prototypes. Implementation then takes place in sprints, either using an agile approach or on a fixed-price basis. Before launch, we test functionality, performance, and usability. Upon request, we can then handle operation, maintenance, and further development. Throughout the entire project, we maintain a collaborative partnership with you, conduct regular reviews, and involve you in all important decisions.

The key difference between hybrid and native app development lies in the codebase and, consequently, the effort involved: Native apps use two separate codebases for iOS and Android, thereby offering the ultimate native look and feel, while hybrid cross-platform development uses a single codebase for multiple platforms, making it faster and more cost-effective. Even major providers like Instagram and Microsoft Teams rely on cross-platform development, which offers the best cost-benefit ratio in most projects. devsuit specializes in this approach.

devsuit develops hybrid cross-platform apps from a single codebase for multiple platforms. For iOS and Android, we typically use the React Native app framework. If a web application is also required, we use the Capacitor app wrapper. Throughout the process, we work exclusively with modern, future-proof technologies. On the backend—often the heart of the software—we rely on Python, one of the world’s most widely used programming languages, using either Django or FastAPI depending on the project.

Depending on your needs, devsuit can serve as an outsourced development department or as a development partner to complement your internal team. If you don’t have your own development team, you can outsource app development entirely to us and receive concept development, design, development, and operations all from a single source, always in close collaboration with you. If you already have a team, we’ll strengthen it with additional expertise and capacity. We’ve successfully implemented both models in projects.

Yes, devsuit develops apps that are secure both technically and legally. Legally, this means they are GDPR-compliant, with minimal tracking and data minimization from the design phase onward, as well as compliance with other applicable guidelines such as accessibility and industry-specific requirements. Technically, we rely on encryption, secure authentication, and role-based access control.

Launching with an MVP is usually the safest approach because it allows you to test your idea in the real market early on, rather than developing a product that misses the mark. We work with you to define the most important core features and typically launch the product within 6 weeks to 3 months, after which we continue to refine it based on real user feedback. This allows you to reach the market faster and at a significantly lower cost than with a full-scale launch right away, while also reducing your investment risk.

Yes, devsuit also takes on existing or unfinished apps, for example, following a change in agencies or a project that has stalled. We analyze the existing codebase, the current state of development, and the technologies used, and then provide you with a well-founded recommendation on where further development is worthwhile and where a complete rebuild makes more sense. We continue to use existing components wherever it makes technical and economic sense.

After launch, we offer hosting, maintenance, security updates, and monitoring for your app, and—upon request—we’ll continue to develop it, for example by adding new features, scaling it, and adapting it to new iOS and Android versions. We typically handle day-to-day operations, but these can also be transferred to your own team. You’ll receive the right to use the developed code and can have it further developed. We, of course, provide a warranty for our development work.

At devsuit, we systematically integrate AI throughout the entire project, from conception through development to quality assurance. For us, this isn’t just hype—it’s the next step in a way of working that has always relied on automation. We review every line of code using a “human-in-the-loop” approach, and whatever the AI can’t reliably solve is handled by the experienced people behind it. This is how we combine the speed of AI with the accountability of senior-level development.
