Difference Between UI and UX

Understanding the distinction between UI (User Interface) and UX (User Experience) is fundamental in the design and development of digital products. Though they are closely related, they refer to different aspects of the user's interaction with a product.

User Interface (UI)

UI design refers to the visual and interactive aspects of an application’s interface. This includes the buttons users click on, the text they read, the images, sliders, text entry fields, and all the rest of the items the user interacts with. This also includes screen layout, transitions, interface animations, and every single micro-interaction. Every visual element, interaction, and animation needs to be thoughtfully designed.

Key components of UI design include:

  • Visual Design: How the app looks. It involves choosing color schemes, button styles, fonts, and overall style.
  • Interactive Design: How the user interacts with the interface. This includes buttons, sliders, icons, and other interactive elements.
  • Branding: Ensuring that the design is consistent with the brand's identity.
  • Layout: Structuring the content on the interface. This involves organizing the elements in a way that guides the user's attention and facilitates navigation.

User Experience (UX)

UX design is more about how the end-user feels when they interact with the product or service. UX design considers the whole process of acquiring and integrating the product, including aspects of branding, design, usability, and function.

Key components of UX design include:

  • User Research: Understanding the needs, wants, and limitations of the users.
  • Information Architecture: Structuring and organizing information in a way that it is easy to find and use.
  • Usability: Making products and systems easy to use and learn. This includes testing designs with users, observing their interactions, and refining the designs based on their feedback.
  • Interaction Design: The way in which users engage with the product. This involves designing the flow of the product and how users move through it.
  • Prototyping and Testing: Creating wireframes and prototypes to test with users, gathering feedback, and making improvements.


  • Focus:
    • UI: Focuses on the look and feel, the presentation, and the interactivity of a product.
    • UX: Focuses on the overall experience, usability, and satisfaction of the user with the product.
  • Tools:
    • UI: Tools like Sketch, Adobe XD, Figma, and InVision are commonly used for designing interfaces.
    • UX: Tools like Axure, Balsamiq, Adobe XD, and Sketch for wireframing and prototyping; user testing tools like UserTesting, Lookback, and others for gathering feedback.
  • Process:
    • UI: Typically comes after UX design, translating the high-level wireframes and prototypes into a polished, final design.
    • UX: Starts from the beginning, understanding user needs, researching, and developing wireframes and prototypes.


UI and UX designers often work closely together. The UX designer maps out the user's journey and flow within a product, ensuring that each step logically follows from the previous one. The UI designer then takes this wireframe and enhances it with visual and interactive elements to ensure the product is aesthetically pleasing and engaging.

In summary, while UI is concerned with the product's interface and aesthetics, UX is concerned with the overall feel of the product and how easy and pleasant it is to use. Both are crucial to the design and success of a product, and they often overlap and collaborate to create the best possible user experience.
