Why are product discovery and prototyping crucial?
To validate an app idea and rule out risks early on and cost-effectively.
How long does an app UX/UI design project take?
An initial prototype (MVP) can often be developed in four weeks, while complex projects usually take two to four months.
How can the success of UX design be evaluated?
In better user retention, higher conversion rates and lower support costs.
Our design process: user-centred, agile and scalable
Good apps impress not only with their appearance, but above all with their simple and intuitive operation. This is no coincidence, but rather the result of a clearly structured UX/UI design process. As a specialised UX/UI agency in Berlin, we consistently place people at the centre of app development. Methods such as design thinking and human-centred design form the basis for successful digital products. Our design process is divided into the following phases:
User Experience Research (UX Research)
Before we begin designing your application, we validate all assumptions. Through user interviews, competitor analysis and data analysis, we explore the problems and desires of your target audience. This ensures that we don't develop features that nobody needs, but instead create solutions that users love.
Prototyping
Design should be something you can experience. That's why we develop interactive click prototypes (e.g. in Figma) that realistically reflect the look and feel of your future app. These prototypes allow you to try out your app before it's implemented, make concepts tangible, gather feedback and make informed decisions.
User-Testing
In usability tests, we work with real users to gather feedback and identify problems so that we can gradually improve your app or test new features with a prototype. This allows us to identify stumbling blocks early on and optimise the UX iteratively.
Visual UI design & design system
We translate your brand into a compelling visual experience. We combine colours, fonts, icons and layouts to create a harmonious overall image that makes your brand unmistakable. A modular design system ensures long-term consistency and easy scaling across all platforms.
Designing successful apps: Why mobile app design follows its own principles
Mobile apps require a precise understanding of native platform guidelines, intuitive gesture control and seamless hardware connectivity. Well-thought-out UX/UI design not only increases user satisfaction, but also boosts usage frequency and long-term app loyalty.
As a UX agency based in Berlin, we know which details make the difference in the App Store.
iOS vs. Android Guidelines
We are proficient in both Apple's Human Interface Guidelines and Google's Material Design. This means we know exactly when consistent platform loyalty is required – and when deliberate deviation creates a strong, independent brand image.
Touch & Gestures
We design interfaces that are optimally designed for thumb operation, integrate intuitive swipe gestures into navigation, and make interactions come alive through micro-animations and haptic feedback.
Performance & Offline-UX
Good design is not only visually appealing, but also works well in situations where there is no stable connection. We design UX flows that intelligently cushion waiting times and enable a consistent user experience even in offline mode.
Five benefits of consistent UX/UI design
- Better usability: A good UX and UI design improves usability by simplifying navigation and interaction with the app and enabling easy and intuitive operation.
- Increasing conversion rate: A responsive design can help users stay in the app longer and return to important features more often, which in turn can increase conversion rate.
- Stärkung der Markenidentität: Ein gut gestaltetes UX und UI Design kann auch dazu beitragen, die Markenidentität zu stärken und die App von anderen abzuheben
- Reduce bounce rates: A user-friendly app with an attractive design, developed in cooperation with our agency, can help to motivate users to engage with your app and return regularly.
- Increasing customer satisfaction: Good UX and UI design helps to increase customer satisfaction by improving the user experience and meeting the needs and expectations of users.

Product strategy: Translating user needs into successful products
Successful digital products are created at the intersection of user needs and supply. Product strategy (product discovery) validates these ideas and precedes UX research. The aim of this phase is to understand which solution is best suited to your goal. This results in marketable and successful products.
Successfully designing accessibility in mobile UX/UI design
Since 2026, the Accessibility Enhancement Act (BFSG) has required many companies to make their digital products accessible to all people. For us, accessibility is not an afterthought, but an integral part of good UX.
