Do you have a project in mind?
Introduction
One of the most common challenges non-technical founders face when building a no-code app is understanding the role that UI (User Interface) and UX (User Experience) design play in the development process.
Our agency frequently sees this stage questioned, as founders often overlook how critical the design aspects are to their app’s success.
In this blog post, we’ll break down what UI and UX design entail, and highlight their significant impact on the functionality, engagement, and overall success of web and mobile apps, drawing on data and real-world observations.
What’s User Interface (UI) Design?
UI (User Interface) design focuses on the look and layout of a product's interface—the visual and interactive elements that users see and engage with such as buttons, icons, colour schemes, typography, spacing, and responsive animations.
User interface design involves designing everything users interact with on their screen.
What’s User Experience (UX) Design?
User experience (UX) design is about how a user feels when they interact with your product, and it involves the entire journey a well-researched user takes when interacting with a product, from the initial encounter to the final interaction.
The goal of UX design is to ensure that the user's experience is smooth, intuitive, and enjoyable.
