The growing challenge of user experience

The other side of digital evolution

With an average of 80% of users less inclined to return after a bad user experience, the digital landscape is unforgiving.

The challenge? Keep an interface that not only evolves with trends, but also remains powerful and intuitive as technology advances.

The high cost of inaction

Ignoring the importance of UX-UI is not only a mistake, it’s a recipe for obsolescence.

Inaction means frustrated users, reduced engagement and, inevitably, lost revenue. In a world where every click counts, can you really afford to be idle?

Your questions, our answers

Discover the questions most frequently asked by our customers about our UI/UX design and usability testing solution. We provide you with clear answers to better meet your needs.

UI (User Interface) is about the visual aspect of your product – how it looks and feels. UX (User Experience), on the other hand, is about how the user interacts with your product, ensuring smooth, intuitive navigation. Both are essential to ensure an optimal user experience.

Test duration depends on the complexity of your project and the type of test recommended (remote, moderate/qualitative, quantitative/video, questionnaire, survey). In general, it takes at least a week from the kick-off meeting to the first results. The steps are as follows 1. initial contact to find out about your problems and advise you on the type of test best suited to your needs ; 2. kick-off meeting ; 3. writing the test protocol ; 4. test launch ; 5. data collection and analysis ; 6. presentation of results at a meeting. Our aim is always to achieve reliable results while respecting your schedule.

Usability testing can reveal interaction problems that you or your team may not have noticed. By understanding the obstacles your users face, you can improve your product to make it more intuitive and user-friendly.

A well-designed interface results in a positive user experience. This is essential to guarantee user satisfaction and keep them coming back. As part of the digital transformation, they are the direct link between the user and your brand, influencing their perception and loyalty.

Absolutely! At Everense, we believe in working closely with our customers. Your feedback is crucial to creating a design that matches your vision while meeting the needs of your users.
