FAQs

How does a web-app work?

A web app runs in the web browser and does not require installation. The frontend uses HTML, CSS, and JavaScript to design the user interface and provide interactivity, while responsive design allows adaptation to different devices. The backend handles requests and hosts the web app, with a database storing and managing the data. Communication between client and server is done via HTTP/HTTPS and APIs. Web servers such as Apache or Nginx host the app, and CDNs distribute static content for speed. Security is ensured by SSL/TLS encryption and authentication/authorization. Advantages of web apps are platform independence, easy updating, and no need for installation, which saves storage space on the device. Web apps thus offer a flexible, accessible and user-friendly solution for many applications.

How do I choose a web development service?

When selecting a web development service, follow these steps:

  • Define your project requirements.

     

  • Look for experience and expertise in relevant projects.

     

  • Assess their technology stack and capabilities.

     

  • Check client testimonials and reviews.

     

  • Evaluate their communication and collaboration approach.

     

  • Discuss budget and pricing.

     

  • Inquire about support and maintenance services.

     

  • Consider compatibility and scalability.

     

By considering these factors, you can confidently choose a web development service that meets your needs and delivers a successful project.

What is the difference between a website and an app?

A website is a collection of HTML documents that are accessible via the Internet and mainly present information. They are displayed in the web browser and are often used to display content such as text, images, and videos. Websites are usually static and offer basic interactivity, such as navigating between different pages.

An app (application) is a piece of software that performs a specific task or function. There are two main types of apps:

  1. Web apps: These run in the web browser and are similar to websites, but are more interactive and functional. They do not require installation on the device and are platform-independent.

     

     

  2. Native apps: These are developed specifically for an operating system (e.g., iOS, Android) and must be installed on the device. They often offer better performance and can access device-specific functions such as the camera or GPS.

The main difference is that websites are mainly used to display information, while apps perform specific tasks and either run in the browser (web apps) or have to be installed on the device (native apps).

Is it a web application software?

Yes, a web application is software. Unlike traditional desktop software programs that are installed on a computer, a web application runs in a web browser and does not require installation on the end device. Web applications offer functionalities that go beyond simple websites and can perform interactive and dynamic tasks, similar to traditional software. They are developed using web technologies such as HTML, CSS, and JavaScript and can be used for both business and personal purposes.

What technology stack does W4 use for its development services?

W4's development services encompass a range of technologies, starting from widely used platforms like WordPress and extending to more sophisticated content management systems such as Drupal. In addition to WordPress, we also leverage TYPO3, another popular CMS known for its enterprise-level capabilities. Furthermore, W4 utilizes the robust features of Drupal, an open-source CMS renowned for its flexibility, security, and scalability. Alongside these CMS platforms, we incorporate Odoo, an all-in-one business management software, to provide comprehensive solutions for various business functions. Additionally, we employ APIOMAT, a powerful backend as a service (BaaS) platform, to streamline the development and integration of APIs. Through our utilization of these technologies, we are well-equipped to cater to clients' diverse needs, ranging from simple websites to complex enterprise solutions. In addition to these platforms, we leverage numerous other technologies to meet our clients' specific requirements.

Do you offer customizations for the web apps based on our individual requirements?

Absolutely! Customization is our specialty. Rather, W4 develops tailor-made web app solutions that perfectly fit your needs. Whether it's interfaces to existing systems, additional functionality, or custom designs, our web app experts work closely with you to realize your vision and create a web application that best meets your goals.

What is the typical process when developing a web app with your agency?

At W4, we design web app development for your marketing transparently and in partnership:

1. Analysis & conception:

  • Common goal definition: What do you want to achieve with your marketing app?

     

  • Target group analysis: Who do you want to address and what makes them tick?

     

  • Competitive analysis: What are others doing in your market?

     

  • Conception of the app functions: Which features serve your goals?

     

  • Creation of a wireframe: sketch of the app structure and user flow

     

2. Design & Development:

  • Developing an attractive and user-friendly design

  • Technical implementation of the functions

  • Integration with CRM, analytics, or other systems (optional)

  • Comprehensive quality assurance & testing

3. Launch & Optimization:

  • Publishing the app

  • Marketing support for your app launch

  • Performance analysis and optimization

  • Ongoing support and maintenance
