Frequently asked questions

  • What is the difference between WebApp, Cross-Platform, Native?

    A web application typically uses HTML, JavaScript, or CSS as its foundation. It doesn't need to be installed because it is run in a web browser after being loaded from a web server. However, using a bookmark enables the creation of a shortcut for a web application on the desktop of a computer or the home screen of a mobile device.

    Cross-platform apps are developed once and can run on different platforms such as iOS and Android. This type of app is often developed using a hybrid development environment that combines the advantages of web technologies and native components (e.g. camera, GPS). This enables developers to develop apps faster and more efficiently, as they do not have to write separately for each platform.

    Native apps, on the other hand, are created and installed for a specific platform. This can be a desktop operating system like Windows or a mobile operating system like Android or iOS. However, it is evident that mobile apps, or so-called "native mobile apps," dominate the app market (or simply mobile apps).

  • What are the costs?

    See our cost calculator.


  • Are there ongoing costs?

    Yes, there are. There are costs for hosting. If you don't already have one, you also need a domain. Third-party services may also result in extra expenses.

  • What are the steps from contact to launch?

    The typical procedure for software projects is as follows:

    1. contact by e-mail or telephone by the client (free of charge)
    2. appointment to get to know each other by telephone (free of charge)
    3. (optional) personal meeting in our offices (free of charge)
    4. Preparation of an offer by us (free of charge or lump-sum payment for technical concept as agreed)
    5. Joint start of the project (down payment of 30 percent)
    6. Iterative processing of tasks, regular exchange of information on progress and possible adaptation requests or suggestions
    7. Final presentation of the software application and final delivery
  • How long does it take for development? When can I use my app?

    For complete custom software projects, i.e. conception, design and implementation of user interface/client, frontend and backend, we usually plan four to nine months from contract signing to launch. For pure interface solutions (synchronization of database/service A with database/service B) we usually plan four to ten weeks. In order to meet our schedules, customer input and short communication and decision-making paths are essential. In addition, we plan for a generous test phase.

  • What do I need to bring as a customer?

    Your Idea ;)

    Ambition to work together seriously on the project for a longer period of time

    Time and energy for regular exchanges and testing
