App Development in Frankfurt: From Design to Marketing
Developing a powerful app for your business doesn't have to be a complex endeavor. Our proven process brings clarity – from the initial idea to go-live.
Conception Phase
App development doesn't just begin with coding. Before actual development, a solid concept is crucial – otherwise, app developers might miss the mark. That's why we bring in experts right from the start: We draft a comprehensive requirements document, our in-house UX/UI specialists develop tailored interfaces, and a professionally built MVP helps avoid costly errors.
Platform-Appropriate Development
Today, every mobile app must be available on all common platforms. Developing a project only for iOS and neglecting Android means being outcompeted by rivals who operate everywhere. Our app agency therefore relies on cross-platform frameworks like React Native – apps developed with these frameworks are hardly inferior to native apps, but development costs are incurred only once.
Robust Backend Architecture
For practical app usage, a standalone solution is almost never sufficient. Users want to store and sync their data – and you need to be able to work with that data. Here too, we know what matters: scalability, convenience, and uncompromising security. Thanks to our expertise, we build our app backends ourselves, ensuring administration is as efficient, convenient, and secure as possible.
Targeted Marketing
The development process doesn't end with a finished app. It needs to be launched in the popular stores, receive continuous updates, and marketing is an art in itself. From websites with award-winning design to market analyses and working with developer consoles – we rely on absolute professionals in every area to cover all bases optimally.
Louis Nell
Louis was never one to do things by halves. As a developer at the railway company, he programmed software that revolutionized the system – and was quickly scrapped precisely for that reason. Frustration turned into opportunity: he quit and founded KNGURU. Today, Louis and his team develop digital products that offer real value – and aren't hindered by corporate politics.
Ivan Prosic
Four years ago, KNGURU was looking for a designer. Ivan responded on Reddit, participated in a design challenge despite a packed schedule – and prevailed. Today, he's our Lead Designer and, according to him, can even operate Figma in his sleep. He has a knack for pixels – and incredible patience for clients who "just want a quick tweak."
Vera Grosse
Vera came as an intern – and simply never left. Today, she juggles clients, projects, and designers simultaneously (and still finds time for a shisha). She's the only person on the team who voluntarily opens Excel spreadsheets – and even with enthusiasm. Plus, Vera can implement project plans faster than Ivan can swim (which he reluctantly admits).
Strahinja Nikolic
Strahinja is not just a designer, but a true go-getter. He builds his own businesses on the side, thinks like a founder, and knows exactly how UX becomes not just beautiful, but profitable. With KNGURU for years, indispensable for years. Always by his side: his dog Bebba, our unofficial team mascot (no, that's not Bebba in the photo).

What makes KNGURU special as an app agency in Frankfurt?
We are full professionals for every step of the development process – from concept and UI/UX to development, backend, and marketing. We don't deliver standard solutions; instead, we implement every idea in a way that makes it stand out from the crowd.
Do I need to have separate apps developed for iOS and Android?
No. With cross-platform frameworks like React Native, we develop a single codebase for both platforms. The resulting apps are almost on par with native apps – but the costs are incurred only once.
What is an MVP and why is it important?
A Minimum Viable Product (MVP) is a lean first version of your app that allows you to gather early market feedback. This ensures that development proceeds in the right direction – before larger investments are made.
Do you also develop the app's backend?
Yes. We build backends in-house, focusing on scalability, security, and efficient administration. This ensures that your app remains stable even with rapidly growing user numbers.
Do you also provide support after launch?
Yes. The app launch marks the beginning of the next phase for us: store submission, ongoing updates, developer console monitoring, and marketing. We don't use freelancers; instead, we employ permanent developers who know and support your project long-term.
What does your app cost?
Naturally, the more features your app needs, the higher the costs will be. That's why we always recommend developing the app as compactly as possible initially and then expanding it incrementally later.

App Agency Frankfurt- Innovative App Development for All Platforms
A Combination of Website and App
Is your budget rather tight? No problem. We'll build you a Progressive Web App – a mobile-first website where our app developers add certain features to make it feel like a real application. Offline features are possible to a certain extent.
Of course, PWAs don't feel quite like "real" iOS or Android apps, and they can't be easily published in app stores. However, they are significantly cheaper, also work on regular computers, and can be launched like an installed app via a launcher shortcut. For simple projects in Frankfurt – such as dashboards or ordering platforms – this is often perfectly sufficient.
One App for All Devices
Do you need a "proper" iOS or Android app? Then we'll realize your project with a cross-platform framework. The latest developments in this area enable apps that feel just like a natively programmed application.
Such apps can be distributed normally through common stores, can access almost all device functions, and, apart from specialized applications, hardly have to compromise on performance.
Programming and App Development in Frankfurt: KNGURU - Your Specialist for Custom Apps
Custom Digital Applications
In today's oversaturated market, it's not enough to simply build run-of-the-mill software. There's far too much of it – and it won't generate interest or retain users.
That's why we don't produce off-the-shelf solutions. We discuss your idea in detail – and then implement it in a way that makes it stand out from the crowd and delights users long-term.
Long-term Support and Further Development
Truly good app development agencies master the entire process. It's not enough to just be proficient in programming if the concept or marketing is then executed unprofessionally or has to be outsourced.
That's why we employ seasoned professionals for every single step – ensuring optimal quality and preventing errors caused by coordination issues.
Digital Transformation as a Strategic Advantage
The same applies to ongoing app maintenance. If developers at the agency change too frequently, new people constantly have to get up to speed – leading to unnecessary extra costs and potential errors.
Therefore, we don't use freelancers, but rather permanently employed developers. These developers usually work with us for many years – and thus always stay on top of your project.
Efficient App Development: The Technologies Behind Our Apps
Compelling Mockups with Figma
Design is paramount for an app – after all, it's the first thing the user sees. To ensure it always meets your expectations, we use Figma. This way, you see the design in advance and can comment on it directly.
And the work for the prototype isn't lost afterwards – thanks to HTML export, we can partially transfer it directly into the actual app, without duplicating work.
React.js for limitless app development
We build the UI with React – so it looks professional and we can implement almost any conceivable feature. If server-side rendering is desired, we supplement the frontend with Next.js. And if it's meant to be a "real" app, we build the necessary functionality with React Native. Fortunately, this tech stack comes from the same ecosystem – so nothing needs to be ported or redeveloped, even if new requirements arise.
Reliable Backend with AWS and Firebase
Of course, the backend shouldn't be neglected. It needs to work even when your project becomes truly popular – and especially then, you can't afford any security blunders.
To ensure this, we rely on Firebase, AWS, or other managed services as needed. The providers handle data security and flexibly provide computing power and storage space. An additional advantage: the many pre-built components also save a significant amount of development budget.
App development with React Native and cloud technologies.
We rely on state-of-the-art technologies in app development to ensure your app remains stable even with a large number of users.
