LED Board: 30 Cheer Effects

LED Board turns your phone into an LED sign. Type a message and show it full screen as LED dots, neon glow, or big plain text. Use it for concert and stadium cheering, airport pickups, ride and car notices, or a shop sign - anywhere your words need to be read from far away.

■ Type, preview, display
· Enter your message on the Edit screen and the preview updates right away. One tap on Display shows it full screen.
· Close and reopen the app and your last setup is still there.

■ 30 effect presets - preview, then pick
· The 30 built-in presets pair a movement, a light beat, a text color change, and a background swap. Preview the motion right in the list, tap Broadcast, or tap Edit and change only the message.
· You can also mix your own: 27 motion patterns (sideways, up and down, diagonal, bounce, zigzag, rotation and more), 6 light beats (blink, double blink, breathing, fade and more), 7 text color effects (smooth color change, rainbow and more), and 4 background effects (invert, blackout, fade).
· From sparkling cheer signs to big plain pickup text, pick it all in one app.

■ Three display styles
· LED dot matrix: round dots light up like a real LED board
· Neon glow: a bright bloom that stands out in a dark venue
· Big text: high-contrast solid letters readable from far away
Choose from 8 text colors and 4 backgrounds, set size and speed, and watch the live preview.

■ Full-screen play
· Your message fills the screen and the display stays on. In Settings you can raise the brightness to the maximum while playing.
· Tap the screen for pause, mirror flip, blink, landscape/portrait and exit, and switch presets on the spot. The controls hide themselves again.

■ Save with a name
· Save your edited sign under a name and keep favorites. The built-in presets stay untouched.
· Bring a saved sign back from the list and play it right away.

■ Send to a friend
· The share button sends a sign image (PNG) together with a setup code (`OWLLED:`).
· Open the app with the code copied and it detects the code, shows a preview, and applies it with Apply Now. No server and no sign-in.

No camera, microphone, location, or contacts permission is requested. Your messages and settings stay on your device, and sharing goes only to the app you choose.
