Web app design is the process of creating a website application that delivers a seamless user experience (UX) and meets users’ core needs with a clear, compelling user interface (UI). Think of Airbnb realizing users wanted a dynamic way of searching for holiday rentals based on different factors like price and location. They created an interactive web app that includes sophisticated filters and a clickable map function—all wrapped up in a minimalist UI. Web app design vs website design Web applications and websites have a lot in common: both are accessed from browsers and prioritize strong UI and UX design to engage users and provide them with an intuitive navigation experience and access from different devices. Unlike native mobile apps, web apps and websites don’t require users to install a program on their device. So what are the key differences between websites and web applications? Websites are primarily informative and content-driven: they provide information that encourages users to take certain actions. They include static pages and they have an open user flow where visitors click around in any order depending on what information they want next. Think of a website advertising a SaaS product: the product itself may be interactive, but the website mainly gives information about the product and team. Web apps, in contrast, are dynamic online applications that let the user perform tasks and manipulate elements in a highly interactive way. Users follow particular paths based on the tasks they want to complete.
