The past year has seen quite a rise in UI design tools. While existing applications, such as Affinity Designer, Gravit and Sketch, have improved drastically, some new players have entered the field, such as Adobe XD (short for Adobe Experience Design) and Figma.
For me, the latter is the most remarkable. Due to its similarity to Sketch, Figma was easy for me to grasp right from the start, but it also has some unique features to differentiate it from its competitor, such as easy file-sharing, vector networks, “constraints” (for responsive design) and real-time collaboration.
