LumiNoir: LED Scrolling Sign

Hold it up in any crowd. LumiNoir turns your iPhone or iPad into a real LED sign. Every letter is built from glowing dots on true black, with the faint grid of unlit LEDs behind it, like the board above a metro platform. HOLD IT UP IN ANY CROWD Type a line, press Play, and the sign fills the screen sideways, stays awake and goes to full brightness until you close it. One big sign for a concert, a stage or a stadium. SET IT DOWN, BOTH SIDES READ IT Table mode lays the sign out twice, one copy turned to face the person across from you. Made for a reserved table, a counter or a quiet message across the room. JUST SAY IT Tap the mic and say it: the sign spells your words as you speak. While it plays, Speak to show puts what you say on the sign as you say it. TÜNEL, A FINER FONT Letters twice as tall, drawn in finer dots, on any look. A one-time in-app purchase you can try on your own words first. LOOKS FROM THE PLATFORM Free looks include Classic Amber, Stadium, Neon, Ice, Taxi, Alert and Warm White, with two-row signs and a lit line badge in every look. The Transit collection, a one-time in-app purchase, adds Platform, Flip-Dot, Night Bus, Metro, Blue Platform and Tram: original looks inspired by transit destination signs. The Party collection adds a flowing rainbow, a pulsing disco and square confetti pixels. Try every look on your own words first. LED colors, dot size and shape, glow, and how bright the unlit dots are, down to pure black on OLED screens, each with a live preview. MEET THEM AT ARRIVALS Two rows and a line badge: a name on top, a word of welcome below, like a real platform sign. SIZE IT BY HOW FAR IT READS Pinch, and the sign shows how far away it can be read, worked out from the letter height on your screen. Let the sign scroll at the speed you choose or stand still and centered: swipe for speed, pinch for size, double-tap to pause. Mirror for a windshield, blink or pulse to catch the eye. YOUR FIRST SIGN IN SECONDS A short guide shows the two ways to use it, then you type or say anything and press Play. A GLOWING CLOCK FOR THE NIGHT An LED clock for the nightstand. Emoji turn into pixel art, and every saved sign is kept in its own look. Free to use, with core looks included; more styles are yours to own with a one-time purchase, no subscription.
