App Development in St. Gallen for the development of mobile applications and websites – KNGURU
Are you looking for an experienced app agency in St. Gallen that transforms your project with precision and technical substance into a compelling digital product? We accompany you from the initial concept to a successful launch.
Over 200+ design projects
Not just developers, but true consultants for your app!
In over 7 years, we've learned what truly makes apps successful. That's why we don't just develop; we also support you with concept, design, and marketing – as a team by your side.
With extensive project experience, we support companies of all sizes – from high-growth startups to established businesses in St. Gallen and throughout Eastern Switzerland. We understand what truly matters to your target audience and develop app solutions that clearly and sustainably stand out in the Swiss market.
Compelling digital products only emerge when development, design, and marketing work together as a cohesive unit from the outset. All disciplines are integrated in-house with us – ensuring consistent results without communication breakdowns. We work agile, rely on modern technologies like Flutter for cross-platform solutions, and ensure that your app meets the high quality standards of the Swiss market – today and in the long term.
This is what structured product design looks like in practice.
From the initial product idea to sophisticated interfaces and scalable systems – our projects demonstrate how thoughtful development and consistent design create real business value.
The app for anyone who loves cars and motorsport!

Clubkit is our white-label solution for smart ticketing. We built it to work like the best bouncer in town.
The platform for pet owners and pet professionals
With PetPlanner, pet owners can find suitable service providers nearby, book appointments online, and keep track of their pet's health data, appointments, and important information at all times.
Recruiting Software on Autopilot
Recruiting is often chaotic and manual. With Funellab, we built a platform that automatically filters, organizes, and perfectly matches applicants.
Energy that adapts to your life.
Clever-PV wanted more than just an app – they wanted to give households control over their energy. Our task: a UX and UI design that makes data clear, intuitive, and understandable.
Complex CAD workflows made simple & intuitive.
Mensch und Maschine stands for CAD and BIM software. We have developed an intuitive solution that simplifies complex processes and seamlessly connects teams.

From a UI dinosaur to a modern management hub.
Avviso manages parking violations and reminders – but its UX/UI still looked like Windows 98. We streamlined the user experience and brought the software into 2024.
App Development in St. Gallen: From Design to Marketing
Developing a powerful app for your business doesn't have to be an overwhelming project. Our proven process provides you with complete clarity at every step.
Conception phase
Before the first line of code is written, we jointly lay the strategic foundation. We analyze target groups, prioritize features, and develop a user-centric design concept – tailored to the Swiss market. User research, competitor analysis, and usability tests are directly incorporated into the design. Using Figma, we build interactive prototypes that can be tested early and immediately incorporate user feedback. If desired, we start with an MVP to measure real user behavior and steer further development effectively.
Platform-Specific Development
We develop agilely – Scrum and Kanban ensure structured, transparent iteration cycles. Whether native with Swift and Kotlin or cross-platform with Flutter and React Native, our apps run stably and performantly on all relevant devices. Ongoing code reviews, automated tests, and targeted security analyses ensure that your product meets the highest technical and quality standards.
Robust Backend Architecture
Behind every robust app lies a well-thought-out backend. We rely on cloud services like AWS, Firebase, and Supabase, as well as frameworks like Node.js and Django. Serverless architectures and microservices ensure efficient operation – even with rapidly growing user numbers. All data is stored securely and in compliance with data protection regulations in powerful SQL or NoSQL databases, fully in line with Swiss data protection requirements.
Targeted Marketing
A technically sophisticated app requires the right marketing strategy. We support you with App Store Optimization, search engine marketing, and social media ads. Our teams analyze the St. Gallen market and your target audience, developing keyword strategies and data-driven campaigns – from retargeting and influencer collaborations to content marketing – for sustainable growth in Eastern Switzerland and beyond.
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 does app development cost in St. Gallen?
The costs depend on the scope, desired features, and technical complexity of the app. An MVP can be implemented significantly faster and more cost-effectively than an extensive platform with custom integrations. After an initial consultation, we will provide a transparent cost estimate for your project.
Do you develop apps for iOS and Android simultaneously?
Yes. We develop both native apps with Swift and Kotlin, and cross-platform applications with Flutter and React Native. For many companies, cross-platform development is the most economical solution, as a common codebase is used for both operating systems.
Can you also integrate existing software or interfaces?
Yes. We integrate existing CRM, ERP, e-commerce, and other third-party systems via APIs and custom interfaces. This seamlessly integrates your app into existing business processes.
Do you also provide support after the app launch?
Absolutely. We support our clients even after launch with maintenance, updates, performance optimizations, and the further development of new features. Since our developers are permanently employed, knowledge about your project is retained long-term.
How do you ensure the app's security and data protection?
Security and data protection are considered right from the conceptual and development phases. We rely on modern cloud infrastructures like AWS, Firebase, or Supabase, conduct regular tests, and develop solutions that comply with applicable data protection requirements.
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 St. Gallen- Innovative App Development for All Platforms
A Combination of Website and App
If your project is clearly defined and you want to start cost-effectively, a Progressive Web App (PWA) can be the ideal choice. PWAs use modern web technologies for offline capability and can be accessed directly via a link – without any store installation.
PWAs are not listed in app stores and don't always achieve the full native user experience. However, they cover all platforms with a shared codebase, can be developed from existing web applications, and function on desktop as usual. For companies in St. Gallen that quickly need a digital solution – such as a customer portal or an internal tool – PWAs offer the fastest and most budget-friendly entry point. If demand grows, the foundation can always be expanded into a full-fledged hybrid app.
One App for All Devices
For those who want to offer a native app experience on all platforms without developing each one individually, cross-platform development is the optimal choice. A shared codebase fully covers iOS and Android – efficient, easy to maintain, and future-proof.
We consistently rely on this approach, working with Flutter and React Native. Modern cross-platform apps are now fully equivalent to native solutions in terms of functionality, performance, and design – while being significantly more economical to develop and maintain.
Programming and App Development in St. Gallen: KNGURU - your specialist for custom apps
Custom Digital Applications
For app projects in St. Gallen, individual precision is paramount. We don't develop standard solutions, but rather concepts precisely tailored to the company, its processes, and its target audience – thereby enabling genuine, lasting differentiation in the Swiss market.
Every project begins with in-depth consultation. We analyze the market and competition, identify opportunities, and develop creative solutions – combined with a design that truly resonates with and convinces users in St. Gallen and Eastern Switzerland.
Long-term Support and Further Development
The go-live marks the start of ongoing operations. Updates, adjustments, and responding to user feedback require a team that knows the product inside out – and doesn't need to be onboarded anew every time.
At KNGURU, all developers are permanently employed, from the initial concept phase to the final release. Your product remains in the same trusted hands – reliably, continuously, and without loss of knowledge.
Digital Transformation as a Strategic Advantage
Successful digital products emerge from the interplay of development, design, and marketing. Companies that outsource these areas to individual external providers lose quality, speed, and overall oversight.
As a full-service agency, we consolidate all expertise in-house. Developers, designers, and marketing professionals work together at KNGURU under one roof – with a shared vision for your product and your success in the Swiss market.
Efficient App Development: The Technologies Behind Our Apps
Compelling Mockups with Figma
To ensure your app starts off in the right direction, we involve you early and actively in the design process. Clickable prototypes provide clarity on the concept and user guidance – long before development resources are committed.
We rely on Figma: collaborative, fast, and cost-efficient. Prototypes can be intuitively tested and immediately refined. The final design is exported as HTML and seamlessly integrated directly into development.
React.js for boundless app development
After prototype approval, we begin technical implementation – consistently based on the React ecosystem. React.js provides flexible, component-based frontends, Next.js optimizes server-side rendering for better loading times, and React Native enables cross-platform mobile apps from a unified codebase. This way, growing requirements don't necessitate a complete rebuild – your investment remains protected long-term.
Reliable Backend with AWS and Firebase
After launch, data is generated – and this data must be stored reliably, securely, and in compliance with data protection regulations, even if usage increases significantly.
We minimize operational overhead by leveraging platforms like AWS and Firebase, which expertly handle peak loads and independently manage backups and data security – allowing you to fully focus on further developing your app.
App development with React Native and cloud technologies.
We use state-of-the-art technologies in app development to ensure your app remains stable even with high user numbers.
