User-centric design plays a significant role in developing applications by focusing on the needs, preferences, and behaviors of end-users. This approach involves gathering user feedback, conducting usability testing, and iterating on designs based on real user experiences. By prioritizing user satisfaction, developers can create applications that are intuitive, functional, and engaging. User-centric design not only enhances user experience (UX) but also increases the likelihood of application adoption and retention. This practice is essential in building products that effectively meet the demands of the target audience.
