CrowdSign

CrowdSign turns your phone into a bright LED-style scrolling message board for clubs, concerts, parties, festivals, and loud rooms.

Type a message, customize the look, and display it full-screen so people can read it from across the room. Use it to request songs from a DJ, find friends in a crowd, celebrate someone, or get a message across when shouting will not work.

Features include scrolling LED text, neon styles, static signs, adjustable speed, colors, backgrounds, direction controls, live preview, and full-screen display.

CrowdSign is simple, fast, and built for noisy places.
