What is a web app — and when do you need one?
A web app is a browser-based application that can be used regardless of the operating system — no installation or app store required. It is often employed when interactive features are central, for example in customer portals, product configurators, or internal company tools.
Thanks to their flexible development, processes can be digitized and optimized efficiently. When used correctly, aWeb appreal added value – for companies as well as for users. Whether as a standalone solution or as a complement to existing systems:Web appsare a central building block of modern digital strategies.
Web, App, PWA? The right way to the digital solution.
Not every digital idea needs an app — and not every app has to be native. A web app agency supports a company not only with development but also in deciding which solution is best for its specific purpose. The advantages of the various web solutions, briefly summarized:
Website
Websites are the right choice when it's primarily about the structured presentation of content and information. They allow easy navigation, are easily accessible, and are ideal for traditional communication or branding purposes.
Web-App
Web apps offer interactive features directly in the browser, are cross-platform, and require no installation. They can be used in a variety of ways—for example for customer portals, configurators, or internal applications—and enable a high degree of flexibility in further development.
Progressive Web-App
Progressive Web Apps (PWAs) are a combination of web apps and native apps. They are available more quickly than native apps and generally offer a better user experience than traditional web apps. Another decisive factor is their flexibility with regard to different devices such as smartphones, tablets, or computers and operating systems.
Native App
Unlike a (progressive) web app, a native app must be installed on a device to be used. Its strengths lie in leveraging system hardware and specific device functions. They also often provide an especially good user experience.
What makes a good web app?
A successful web app is more than just technically feasible. It is intuitive to use, visually appealing, high-performing, and secure. Good web apps:
01Solve real problems.
zero twoProvide clear user guidance.
03work on all devices.
04can be further developed flexibly.

Typical challenges in web app development
When developing web apps, frequently recurring questions arise that are independent of industry or company size. These include, for example:
Which technology fits the requirements and the existing infrastructure?
How is a user interface created that is intuitive to use?
How can existing systems and data sources be integrated effectively?
How can we ensure that the application remains maintainable and scalable in the long term?
Get to a working solution faster — with a specialized web app agency
A web app is not just a web app. Achieving sustainable results requires strategic thinking, UX expertise, and technical know-how. A specialized web app agency brings exactly the interplay of experience, process orientation, and design competence that distinguishes successful projects. Agencies that focus on app design and web app development ensure that technical feasibility, user-friendliness, and business goals are integrated from the outset. This produces not just a functioning application but a solution that delivers long-term value: it is scalable, maintainable, and precisely tailored to the specific requirements.
Our services as a web app agency
Needs analysis & consulting
The foundation of every successful web app is a thorough analysis of the requirements. Even before actual development begins, it is defined which features are needed, which goals should be pursued, and how the application can be meaningfully integrated into existing processes.
UX/UI concept
A well-thought-out app design is essential for user acceptance. That's why intuitive usability and a clear visual language are the focus during the design process. The result is a user-friendly interface that works convincingly across all devices, from desktop to smartphone.
Technical implementation
The technical implementation is carried out based on the developed concept. Modern frameworks and programming languages are used to create a high-performance, stable, and future-proof web app. Interfaces ensure seamless communication between the frontend and backend as well as with external systems.
Testing & Launch
Before a web app goes live, it is thoroughly tested: technically, functionally, and from a user-experience perspective. The goal is to develop a stable application that runs smoothly and performs convincingly in real-world usage scenarios.
further development
Even after launch, we continue to support projects — for example with technical updates, new features, or optimization of existing components. This keeps the application relevant over the long term and allows it to grow with the company’s needs.

Frequently asked questions about working with a web app agency
What does a web app agency do?
An agency supports companies in choosing the right web application, assists with planning, conceptualization and design, and handles the development of the custom app.
What are the biggest advantages of web apps over native apps?
A web app doesn't need to be tailored to different platforms and isn't dependent on an app store; it runs in any browser, which usually makes development easier.
How do web apps differ from traditional websites?
While websites primarily convey content, web apps are functionally oriented. They enable interactions, for example through user accounts, forms, configurators, or internal applications. Technically, they resemble software solutions rather than pure content sites.
What functions can a web app perform?
Web apps can be used for a wide variety of purposes. They are often used in the e‑commerce sector or serve as a platform for customers to obtain information and to communicate.
Can a web app be used offline?
In many cases, yes — especially with Progressive Web Apps (PWAs). They can be equipped with offline capabilities so that certain content and functions remain available even without an internet connection.
