FAQ

It fills your screen with a simulated LED dot-matrix panel and scrolls whatever you type across it. You control the text colour, the background, the speed, the direction, the size, the border and the blinking — then hold the phone up so people can read it.

Yes. Emoji render as lit dots along with the rest of the text, so they scroll with the message rather than sitting outside it.

Yes — any banner can be exported as an animated GIF and then shared or saved to your device. That makes the same message usable in a chat, a story, or a group thread, not just in your hand.

Yes. Everything you have shown is kept in the history tab, so a sign you made for a concert last year is one tap away the next time you need it.

Yes. It is on the App Store as LED Banner: LED Scroller Board and on Google Play as LED Banner - LED Scroller. Same app, different store titles.

Running a bright screen at full brightness with the flashlight blinking will use power quickly — that is true of any app doing this. For a long event, turn the flashlight off and drop the brightness a little; the banner is still perfectly readable.
