App Development in Biel: From Design to Marketing

Building a powerful app for your business doesn't have to be an opaque project. Our proven process ensures transparency – from the initial idea to launch.

01

Strategic Concept & UX Design

Concept Development, User Experience Design, and Prototyping

Every successful project begins with a deep understanding of your vision. In our discovery workshops, we conduct a precise requirements analysis and identify technical hurdles early on. Defining your target audience is central: Who uses the app and in what context? We design interfaces that engage users and measurably support your business goals.

02

Native & Cross-Platform Development

App development in Biel for Android and iOS

We choose the technology that perfectly fits your budget and performance requirements. For maximum performance and direct hardware access, we use Swift for iOS and Kotlin for Android. With cross-platform frameworks like React Native and Flutter, we develop a single codebase for both platforms – ensuring enormous efficiency in development and maintenance, without compromising on performance or look-and-feel.

03

Backend & API Development

Scalable and powerful backend solutions for your app

The core of every app remains invisible to the user but is crucial for stability. We develop a scalable backend that grows with your business. With cloud solutions like AWS and Firebase, your data is always available – with maximum data security and an architecture optimized for speed and high loads.

04

App Launch & Maintenance

First-class support from launch to further development

Our service doesn't end with the finished code. We handle the entire publication process in the Apple App Store and Google Play, including all regulatory requirements. After launch, we ensure long-term success through continuous maintenance, updates, and permanent performance monitoring – based on real user behavior.

Louis Nell

CEO

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 for precisely that reason. Frustration turned into opportunity: He quit and founded KNGURU. Today, Louis and his team develop digital products that offer real added value – and aren't hindered by corporate politics.

Ivan Prosic

Lead designer

Four years ago, KNGURU was looking for a designer. Ivan responded on Reddit, participated in a design challenge despite a packed schedule – and came out on top. Today, he's our Lead Designer and, by his own admission, can even operate Figma in his sleep. He has a knack for pixels – and incredible patience for clients who "just want a quick adjustment."

Vera Grosse

Project Manager

Vera joined us 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 does so with enthusiasm. What's more, Vera can implement project plans faster than Ivan can swim (which he reluctantly admits).

Strahinja Nikolic

Graphic and Product designer

Strahinja is not just a designer, but a true doer. He builds his own businesses on the side, thinks like a founder, and knows exactly how UX becomes not just beautiful, but profitable. He's been with KNGURU for years, and has been indispensable for years. Always by his side: his dog Bebba, our unofficial team mascot (no, that's not Bebba in the photo).

What advantages does a custom app offer my company in Biel?

A custom-built app improves internal workflows, automates processes, and creates direct digital communication with your customers. As a local agency with knowledge of the bilingual Seeland region, we develop solutions precisely tailored to your market and target audience.

Do you develop native or cross-platform apps?

Both. For maximum performance, we use Swift for iOS and Kotlin for Android. For efficient development with a fast time-to-market, we rely on React Native and Flutter – a single codebase for both platforms, without compromising quality.

Which technologies do you use?

We work with React Native, Flutter, AWS, Firebase, and Figma. For specific requirements, we integrate custom API architectures and modern cloud solutions – depending on the use case.

What happens after the app launch?

We provide continuous maintenance, regular updates, and permanent performance monitoring. Bottlenecks are immediately resolved, and the app is continuously improved based on real user behavior.

What makes KNGURU stand out as an app agency in Biel?

We combine Swiss quality and precision with deep knowledge of the local market in Seeland. You get everything from a single source – from conception and development to submission in the App Store – with maximum transparency and clear communication.

How much does your app cost?

The more features your app is intended to include, the higher the development costs generally are. Therefore, we recommend starting with the leanest and most clearly defined version possible and then expanding the app strategically later. This way, costs can be reduced, initial results achieved faster, and user feedback incorporated into further development early on.

App Agency Biel - Innovative App Development for All Platforms

progressive web apps

A Combination of Website and App

If your project is clearly defined and you want to start with a lean budget, a Progressive Web App (PWA) can be the smartest choice. PWAs use modern web technologies for offline capability and can be launched directly via a shortcut – without store installation.

While PWAs are not discoverable in app stores and don't always achieve the full native user experience, they cover all platforms with a single codebase and can be developed cost-effectively from existing web applications. For companies in Biel that quickly need a digital solution – such as a booking portal or an internal dashboard – a PWA is often the fastest and most cost-effective path. If demand grows, the foundation can always be expanded into a full-fledged hybrid app.

cross-platform apps

One App for All Devices

These apps combine the best of both worlds: A single codebase serves both iOS and Android users – efficient, low-maintenance, and future-proof.

We favor this approach and rely on Flutter and React Native. Modern cross-platform apps are now on par with native solutions in terms of functionality, performance, and design.

Programming and  App Development in Biel: KNGURU - your specialist for custom apps

Focus on User Experience & Design Excellence

The quality of an app is measured by its usability. We combine technical expertise with contemporary UX/UI design tailored to your users' needs.

Through intuitive user guidance and aesthetic interfaces, we ensure that your app is not only downloaded but also enjoyed daily – thus becoming a true growth driver.

Scalable Solutions for Future Growth

Instead of disposable products, we develop digital ecosystems. Our solutions are designed to evolve with your business.

Whether you're just starting out or aiming to reach the whole world – our cloud architectures and flexible structures adapt to every requirement, today and tomorrow.

Full-Service from idea to store management

With us, you get everything from a single source. We not only assist with development but also handle complex tasks such as store optimization (ASO) and submission to Apple and Google.

We solve the technical challenges – so you can fully focus on your core business.

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 directly integrated into the implementation without detours.

React.js for limitless 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 means growing requirements won't necessitate a 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 with high performance, even as usage significantly increases.

We reduce operational overhead by using established platforms like AWS and Firebase, which confidently handle peak loads and largely manage backups and data security independently – allowing you to fully concentrate on further developing your app.

App development with React Native and cloud technologies.

We rely on cutting-edge technologies in app development to ensure your app can handle high user traffic.
