UX check with UID: interview with nutrilize founder Alexander Weber

Longevity, fitness and personalized nutrition are experiencing a real boom – and with them a growing number of digital applications that support users and coaches in their everyday lives. However, in an increasingly saturated market, it is not just the idea, but above all the user experience that determines which solutions will prevail in the long term.

In this interview, Alexander Weber, founder of nutrilize, talks about how digital tools effectively connect coaches and clients, the challenges that arise when developing such platforms and why a well thought-out UX is crucial for sustainable success. With nutrilize, he has established two applications: a platform for connecting coaches and an app for structured support and progress analysis for clients.

UID supported nutrilize as part of an expert review and identified targeted optimization potential – from more efficient processes to improved user guidance. In this interview, Alexander Weber provides insights into the collaboration and shows how targeted UX optimization helps to take digital healthcare solutions to the next level.

How did you find working with UID?

Alexander Weber: Very pleasant. UID strikes a good balance between professionalism and a relaxed working atmosphere. The collaboration was also very efficient and the time required on our side was kept within limits. Overall, everything was well coordinated and neatly documented.

How did the collaboration actually work?

We started with a one-hour briefing meeting in which we exchanged all the important information, discussed the roadmap and defined our current UX difficulties as the focus for the UX check. This was followed by a UX check lasting around two weeks. We concluded the project with a debriefing of the findings, including positive and negative examples, a classification according to importance and concrete options for action, both independently and in further collaboration with UID. What struck us as particularly positive was that UID came up with suggestions for the further development of our product, which was very valuable.

How do you assess the value of good UX, especially in the areas of longevity, fitness and wellness?

Good UX is particularly important in our field because our apps are used regularly on a daily basis. A poor user experience can directly hinder recurring use. What’s more, apps in this environment are the first point of contact with topics such as fitness and health for many users. This brings with it content-related requirements: good UX helps users to quickly find their way around a new area.

Has your view of UX changed as a result of the project?

Yes, absolutely. It has become even clearer to me that many design decisions trigger unconsciously learned reactions in the user, often without being consciously controlled by the designer. This shows how important it is to know existing conventions and use them in a targeted manner.

Which impulses have helped you the most?

The focus on conformity with expectations and consistency was particularly valuable. If an app does what users intuitively expect, it becomes much easier to use. A positive side effect: consistent design also makes development more efficient because you can always fall back on existing components instead of reinventing the wheel.

Are there any other points you would like to emphasize about the project?

Yes, two things are still important to me: the strategic input from UID provided really good ideas for further development. And the direct comparison of our app with other products from the industry was very informative, because it showed specifically where we stand and what is possible.

The interview was conducted by Svenja Mahl. Thank you very much for your time, Alexander Weber!
