GlowVox: LED Scrolling Text

Talking LED sign & megaphone

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Buy once, keep it: no subscription, no ads. Scroll it, shout it, and let the background music duck out of the way. Your iPhone becomes a handheld LED sign — and a megaphone. GlowVox scrolls giant glowing text across the screen and, when you want it to, shouts that text out loud on a loop. Night market, concert crowd, airport arrivals, a proposal after dark: hold it up and people see you from the other end of the street. WHAT IT DOES • Full LED engine. Three marquee lanes, glitch, typewriter, strobe, neon glow, gradient shimmer and mic-reactive beats — with a built-in photosensitivity guard on the fast flashing. • Say it out loud. Text-to-speech loops your wording with sweet, deep or cartoon voice effects, or loops your own recording, with up to +6 dB of outdoor gain for a Bluetooth speaker. • Background music that knows its place. Loop a track behind the sign; the instant your shout-out starts the music ducks out of the way, then fades back when you stop. • Photo to LED dot matrix. Bright pixels become lamps, dark ones stay black — pets, logos and idol photos all light up. • Lock Screen pickup sign. A Live Activity keeps it on the Lock Screen and Dynamic Island, so the screen stays cheap on battery and you still never miss them. • Ready-made templates across six scenes: market stalls, fan chants, proposals, parties, airport pickups and everyday utility signs like queue numbers and parking. • Live variables. Put {time} or {date} in the text and it keeps itself current. • Landscape, upside-down and mirror modes, adjustable font, size, speed and blinking, and a searchable color library. • Siri shortcuts to light a saved sign without opening the app. • Export and share as GIF, video or screen recording — and export any recording as MP3. • Stop timer at 15/30/60/120 minutes, plus a low-battery prompt that offers power-saving mode. PRIVACY, PLAINLY No developer servers. No data collection. No ads and no analytics SDKs. Your recordings and signs stay on your device. The in-app purchase covers the full template, effect and motion library, text-to-speech and recording loops, background music, photo signs, GIF / video / screen-recording export, saving more than 3 signs, and playback without the watermark.
