Mduyen Scroller: LEDSign

Mduyen Scroller: LEDSign turns your iPhone into a bright, full-screen sign for concerts, airport pickups, parties, live events, and everyday messages. FULL-SCREEN LED SIGNS Enter any message and adjust its size, scroll speed, direction, text color, and background color. Choose scrolling, still, blinking, or scrolling-and-blinking modes. LIGHT SHOWS Fill the screen with smooth gradients, pulsing colors, or random flashes. Pick a ready-made theme or build a custom palette with up to eight colors. GROUP SYNC Keep several phones changing color on the same beat using device system time. Once everyone has the same setup, the animation stays synchronized even when each person enters full screen at a different moment. SHARE A COMPLETE SETUP Create a QR code or invite link after configuring a sign or light show. Friends can open it to import the same message, colors, speed, effect, and sync settings. SCREEN LOCK Lock the controls during full-screen display to prevent accidental taps. Press and hold the screen to unlock. PRIVATE AND OFFLINE No registration or login is required. Favorites, history, and settings stay on your device. The app contains no ads or third-party analytics. Safety note: Rapid flashing may cause discomfort or trigger photosensitive reactions. Avoid prolonged close viewing.
