Frequently asked questions

Which platforms are supported for app development?

We offer app development services for a variety of platforms, including iOS (Apple), Android (Google) and cross-platform solutions that work on both iOS and Android.

How long does it take to develop an app?

The development time for an app can vary depending on its complexity, features and design. However, we work closely with our clients to set realistic timeframes and keep you updated on progress throughout the development process.

Do you also offer app maintenance and support after release?

Yes, we also offer app maintenance services and technical support after release. We help you with troubleshooting, implementing updates and security patches, and keep your app up to date at all times.

What steps does the app development process involve?

The app development process typically involves several steps, including conception, design, development, testing and finally publication on the relevant app stores. We guide you through every step of the process and keep you continuously updated on progress.

Which framework is used for development?

We use the Flutter framework for app development. Flutter is an open-source UI toolkit from Google that enables developers to build cross-platform apps with a single codebase. With Flutter, we can develop high-performance and aesthetically pleasing apps for iOS, Android and the web, resulting in more efficient development and a consistent user experience across different platforms.

What are the costs for developing an app?

The cost of developing an app varies depending on various factors such as functionality, design, platform, complexity and development time. A simple app with basic features may cost less, while a highly complex app with extensive features and custom design may cost more. It is important that we understand your specific requirements in order to provide you with an accurate cost estimate for your app project.

What is the difference between developing and maintaining an app?

App maintenance, on the other hand, refers to the ongoing care and updating of an existing app. This can include troubleshooting, implementing updates, security updates and monitoring performance. While development is the initial process of bringing an app to market for the first time, support ensures that the app remains successful in the long term and meets the changing needs of users.

Why is app maintenance and support important?

App maintenance and support are important to ensure that the app functions optimally, remains secure, and complies with ever-changing requirements and standards. Regular updates and upgrades can fix bugs, close security vulnerabilities, and improve app performance. In addition, continuous maintenance allows for adaptation to new operating system versions, devices and technologies to ensure smooth functionality across different platforms. Maintaining and updating an app is therefore crucial to optimising the user experience, increasing user retention and ensuring the long-term success of the app.
