If you are able to work in complex design tools such as Sketch, Figma, and Adobe XD, good for you! What makes Uizard significantly different from these platforms is the much gentler learning curve, making it ideal for people without former experience with complex UI/UX design software.
In other words, if your goal is to create pixel-perfect UI design, graphic design, infographics, or illustrations, and you have the technical skills for it, it's best to use a vector design software. However, if you want to quickly and effortlessly create prototypes of websites and mobile apps, Uizard is a better choice for you.
In Uizard, you design with interactive components and templates, such as buttons, paragraphs, login forms, pages, etc. Uizard enables you to simply drag-and-drop pre-made components and templates, or create your own. No need for a tutorial to use Uizard — it's fast and easy.
