App agency – our services

Whether you're thinking about developing a new app or upgrading an existing one, we're the right partner for you. From creating an initial concept to long-term maintenance and ongoing development, including updates, we can offer your company the full range of skills and services you'll need.

Strategy & app design

One thing is crystal clear to us: a successful app needs a well thought-out strategy. Together, we will analyse your requirements and goals, the market and your audience. This serves as the foundation for a customised app concept. We prioritise identifying core functions and highlighting unique selling points. We establish clear criteria to measure success later on. Through comprehensive consulting, we make sure that your app not only delivers on a technical level, but also contributes to achieving your business goals while offering real added value to users.

User experience & design

The success or failure of an app is determined by the experience users have with it. Our team believes it is essential to combine aesthetic design with intuitive usability. We make sure that the UX design also reflects your brand identity. Through extensive testing, we optimise the user interface to achieve low bounce rates and high target group loyalty.

App development & programming

Modern frameworks and efficient development methods lay the foundation for the technical implementation of an app solution. Depending on your requirements, we develop native and mobile apps for iOS and Android or use cross-platform technologies. As an app agency, we work on app development in line with agile principles, relying on sprints and feedback loops.

App testing and quality assurance

To prevent bugs from showing up later, we prioritise comprehensive quality assurance. We test the app on various devices and operating systems to ensure that your product offers exactly the user experience you envision in all variants. With automated testing combined with manual checks by our team, we as an app agency ensure that we can identify and fix errors early on. This ensures that your app works reliably under all conditions. Security audits and data protection checks are also part of our standard service.

App store optimisation & launching your app

To ensure that everything goes smoothly when your app is launched, we plan it meticulously as your app agency. We take care of the preparations for publication in the app stores and create complete store entries with optimised descriptions, including insights into the app. This improves the visibility and ranking of your app from the moment it is launched. Depending on whether your app works with a subscription model or you are pursuing other monetisation strategies, we will advise you accordingly. We will develop a launch plan that generates attention and ensures downloads right from the word go.

Maintenance & ongoing development of your app

Once your app has been successfully launched, we offer you a support and maintenance package as your app agency. This ensures that regular updates are installed, bugs are fixed and performance is continuously optimised. To this end, we analyse user data and feedback to keep your app one step ahead. Together, we develop a roadmap for new features and functions.

Backend development & API integration for your app

Apps need a powerful infrastructure in the background. As an app agency, we set up a scalable backend system and cloud solutions for you. We integrate existing systems via APIs to ensure smooth communication between your app and your server and that you can access all data at any time.
