Why we picked it A free, no signup whiteboard with a deliberately hand drawn look, ideal for sketching screens and flows without falling into pixel perfect design. The rough style keeps everyone focused on structure and the user's path, which is the point of a version one sketch. You can share a link with your developer in seconds and mark up ideas together.
