Advantages of web app development

Compared to traditional websites, web apps offer interactive features, dynamic user experiences and enable complex applications directly in the browser – similar to native apps.

Web apps have even more advantages:

✓	Easy updating: Updates to web apps are performed automatically when a user reloads a web app.
✓	Cross-platform compatible: Unlike traditional apps, which must first be downloaded and installed from the App Store, they are platform-independent and load directly in the smartphone browser. This means they work seamlessly on almost all devices.
✓	Large target group: With web applications, you can reach the largest possible target group without having to develop separate app versions for iOS and Android.

Customised solutions – Why many companies choose to have their web apps developed

To help you realise the benefits of web apps, we prefer to use established frameworks such as React or Next.js for web app development. For web apps with database access, we use various content management system providers. As professional web app developers, we also place great importance on:

✓	High data protection standards: GDPR-compliant user analysis and hosting
✓	Top-Speed: Supports code splitting, optimised images, fonts and scripts for fast loading and navigation within the web app.
✓	Scalability: Next.js is based on React and is ideal for static or dynamically generated pages and API integration.
✓	SEO optimisation: Web apps that are rendered on the server side are optimised for Google searches.

How much does it cost to develop a web app?

The cost of developing a web app can vary greatly. Factors that significantly influence the cost include the number and complexity of the desired features, the necessary integrations with existing systems, and the requirements for the app design.

Simple web apps with basic functions often start at a few thousand pounds and can also be programmed by a web app developer. Extensive applications with complex logic, different user roles, API integrations, or a large number of features, on the other hand, can quickly cost over €100,000 or more and are better handled by a web app agency.

In order to provide you with a reliable cost estimate, we need to understand your requirements and goals in detail. We would be happy to advise you without obligation and discuss various technical options that fit your budget.

Contact us for a non-binding initial consultation. We look forward to learning more about your app idea and supporting you in its successful implementation.

From concept to finished web app

Requirements analysis & technology consulting

As a web app agency, it is important to us that we understand exactly what your goals are, how different user groups will later use your web app, which functions the web app must have and which existing systems it should be integrated into. Based on this information, we can discuss which app development framework is the best fit and develop a technical concept.

Proof of Concept

A proof of concept (PoC) is often created to test the feasibility of your web app idea. For this purpose, we develop an interactive prototype of your web app. This enables us to test the technical feasibility, quickly identify potential problems and also receive important feedback from our customers or users at an early stage.

UI/UX Design

The user interface (UI) design and the user experience (UX) are of great importance for the success of your web app. Intuitive navigation and a user-friendly, appealing design improve user retention and can help to attract new target groups. One major advantage is that we have already been involved in the design of almost 100 web apps and apps. This experience also flows into the design of your web app.

Web app programming

The actual development of the web app takes place in the implementation phase. Now we implement your web app idea based on the proof of concept and the previously defined requirements. We often rely on Next.js for web app development, as this framework offers various advantages in terms of performance, integration of other technologies and scalability.

Testing

Before a web app is published, it must of course be thoroughly tested. This includes: Functional tests, performance tests, security tests and usability tests. A thorough test phase helps to ensure the quality of the web app and avoid problems at launch.

Publication and maintenance

After successful testing, the web app is ready for publication. Automated deployments, monitoring and regular updates ensure security, availability and continuous improvement of the user experience. Tracking technologies provide the marketing department with important insights into user behaviour and acquisition.

Examples of web apps

Web apps are usually highly interactive, unique applications that address specific use cases. Prominent examples of popular web apps include Google Docs, Gmail and Facebook. Whenever factors such as individual user experience, seamless integration into existing systems or the handling of online-based processes are important, web apps can be a good solution.

What is the difference between SaaS and web apps?

Both web apps and most SaaS apps are loaded via the browser. However, the term web app refers to a specific app development approach, whereas SaaS apps (Software as a Service) describe a business model: A SaaS app is a special form of web app that is provided as a service via the Internet – typically on a subscription basis. So while every SaaS app is a web app, not every web app is automatically a SaaS solution.

Trust through quality and expertise

Thanks to our extensive experience from numerous successfully completed projects, Hybrid Heroes is one of the few German agencies recommended by OMR Reviews.
