Fast Load Times, Smooth Performance

We use high-performance technologies and clean architecture to ensure your web app loads quickly and remains stable even with high usage. This boosts user satisfaction and reduces bounce rates – especially important for mobile applications.

How Your Web App Project Works with Us

Initial Consultation & Requirements Analysis

In a free initial consultation, we clarify what you want to achieve by developing your web app—whether it’s a customer portal, a Progressive Web App (PWA), or a custom solution. We analyze your business processes, target audiences, and technical requirements, and apply our expertise where it matters most.

Structure, Design & Prototype

Based on your goals, we create wireframes, design concepts, and an interactive prototype. We ensure a consistent user experience—whether you’re planning a web app, native app, or hybrid solution. This gives you an early, realistic preview of your application.

Agile Web App Development

Our developers implement your project in iterative sprints. You receive regular milestone releases, can test features, and actively shape the outcome. Whether it’s a PWA, customer portal, or scalable web app—our process is structured and efficient.

Backend, APIs & Data Logic

We develop high-performance APIs and a robust backend to ensure seamless communication between your app, server, and database. This enables efficient data handling—a critical foundation for long-term performance and scalability.

Testing, Quality Assurance & Go-Live

Before launch, we thoroughly test your application on all relevant devices and browsers—whether web, iOS, or Android. We support you through the go-live phase and take care of the technical rollout so everything runs smoothly.

Updates, Maintenance & Further Development

After launch, we make sure your web app continues to succeed. We handle regular updates, perform maintenance, and develop new features as needed—whether it’s for an app or a growing portal.

FAQ Web App Development

What is the difference between a web app and a native app?

The main difference is that web apps are accessible via a web browser, while native apps are developed specifically for platforms like Android or iOS. Having a web app developed allows for cross-platform use across multiple devices, whereas native apps often deliver better performance but work only on specific devices.

What are the benefits of a Progressive Web App (PWA)?

A Progressive Web App (PWA) combines the benefits of web apps and native apps. PWAs are accessible via browsers but still offer an app-like experience, including push notifications and offline functionality. If you’re wondering whether a PWA is right for you, it’s often a great choice if you’re looking for a fast, cost-effective solution that works across all devices and is easy to maintain.

Can my web app be made available on all devices?

Yes, a well-developed web app is platform-independent and works on all common devices, such as desktops, tablets, and smartphones. With modern web technologies, we ensure that your web application runs seamlessly across devices—without needing to create separate versions for each one.

How can I publish my web app on the Apple App Store?

Although web apps are typically accessed through web browsers, it is also possible to integrate a web app as a PWA into the Apple App Store. This requires special preparation and possibly a wrapper app that packages your web app into a native app. We’ll advise you on how best to optimize and publish your app for the App Store.
