GlowVox vs CloudZao

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. • Fan-color glowstick. One tap turns the whole screen into your idol's color, pulsing in rhythm, with the name on top in high contrast. • Fill-in templates. Change the name or price and go; no rewriting the whole sign. • Landscape, upside-down and mirror modes, adjustable font, size, speed and blinking, and a searchable color library. • Hold-up lock. Freeze rotation and gestures while you hold the phone overhead, so nothing flips or pauses by accident. • Built for long shifts. All-day mode lowers the frame rate or switches to a clear still sign, and the app suggests it when the phone runs hot or Low Power Mode is on. • Flashlight: steady, strobe, SOS, or pulsing with the music. • Sync several phones. Nearby phones show the same sign in step, or become a remote: pause, next sign, brightness and one-tap shout. • Siri shortcuts jump straight into stall or cheer mode, a Home Screen widget relights your last sign, and one tap resumes your last playlist. • 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 a black-screen mode: the screen goes dark while the shout-out keeps going.
