LED Scroller: Scrolling Text

Turn your phone sideways and scroll your message like a real LED sign.
Hold it up at a concert, tell a driver their headlights are off, or greet someone at the airport — in letters big enough to read from far away.

■ Open it and play
The first screen is the text field. Type, tap Play, and your message scrolls full-screen in landscape. No sign-up.

■ Sharp characters, even complex ones
Most LED banner apps draw text with coarse on/off dots, which blurs detailed characters. This app uses about 28 dots per letter and dims each dot by how much of the stroke it covers, so complex Japanese, Chinese, and Korean characters stay readable.
Still messages wrap automatically and use a finer grid when they get long.

■ Made for switching at concerts
Your messages glow on the home screen, ready to go. Tap one to play it, then swipe left or right to switch to the next. The order never changes while you play, so you can follow your plan in a dark venue.
