User Interface Design

The importance of user interface design: Merging aesthetics and functionality

We strongly believe in the importance of designing attractive and easy to use digital products.

Our philosophy is based on the idea that a well-designed interface should be not only aesthetically pleasing, but also highly functional. We want to share with you the importance of a design that is able to satisfy the needs of the users, always keeping in mind the client's goals.

User interface design plays a vital role in the success of a digital product. It is not only about making the aesthetic appealing, but also about ensuring a smooth and effective user experience. When a user comes across a well-designed interface, he is able to perform his tasks easily and smoothly. The interface becomes a tool to achieve its goals efficiently.

Our approach to user interface design is all about creating a marriage between aesthetics and functionality. We believe that aesthetics should be functional so that design is not an end in itself. An appealing but non-functional interface risks frustrating users and negatively impacting the overall effectiveness of the product.

Furthermore, we strongly believe that the creation of a design system is essential to ensure consistency and cohesion in the user interface of a digital product. A set of design guidelines, components, and principles that define the appearance and behavior of the interface in a consistent way. This allows users to easily familiarize themselves with the product and leverage their prior knowledge to successfully interact with the interface.

How does glueglue work and what are your areas of expertise?

We start with an in‑depth needs analysis, considering product and business objectives in the medium to long term. We often begin with visual identity: we assess positioning, analyze competitors, and identify opportunities to improve brand and image. We then move to UX/UI: we conduct a professional UX Review to identify areas for intervention and improve the usability of the site or app. We design the User Journey Map, mapping all touchpoints to understand real use cases and where to create tangible value. We create wireframes and share an interactive prototype that defines the functionality, structure, and interactions of each page. Once the wireframes are consolidated, we refine the interface design in detail to ensure a pleasant and consistent experience. Finally, our developers implement the product with modern technologies such as React, Flutter, Symfony, Svelte, Node.js, and more, ensuring quality, stability, and pixel‑perfect results.

Do you use artificial intelligence?

Yes, on two fronts. Inside our own method, where it helps designers explore and compare several directions in hours instead of days, and helps engineers accelerate repetitive phases and raise quality with broader review and testing.
And inside the products we build for our clients: document and file analysis, predictive models, understanding of unstructured text, semantic search, assistants and automations.
For us it is a multiplier, not a shortcut: people stay in the loop and every AI feature has a success metric defined before it is written. Read how we use AI.

How much does it cost to entrust you with a digital project?

We believe in transparency: talking openly about budget helps create value for both sides. Every client has different needs, which is why we don’t use a fixed price list. Instead, we take the time to understand the context and propose a tailored approach with a fair, appropriate investment. Our UX/UI design projects start at €15,000, while branding engagements begin at €8,000. Mobile app development typically requires an investment starting from €40,000, web apps from €30,000, and websites from €15,000. Our average hourly rate for consulting is €70/hour.
