Quiet Shout transforms your screen into a digital banner that commands attention anywhere. Flash giant words that fill the display edge to edge, or scroll long messages like a classic LED ticker. Either way, your message lands.

No account. No setup. Type it, tap it, and you are already visible across a packed arena.

Everything you need to be seen

Three LED styles that actually glow

Classic for clean bold letters. Neon for a radiant sign that burns through the dark. Dot Matrix for the authentic LED ticker made of glowing dots, with text scrolling through a fixed grid exactly like the real thing.

Rainbow text, one switch

Flip a single toggle and every shout plays in full rainbow color — in any style, in either display mode.

Quick Shout for instant impact

Type and play in seconds. No saving, no menus, no friction. Your message is live before the moment passes.

Hey Siri, shout it

Built-in Siri shortcuts work the moment you install. Say "Hey Siri, Quiet Shout taxi sign" and your message is on screen before you even unlock.

Home Screen widget

Your saved shouts sit one tap from the Home Screen, styled to match your theme color.

Automation ready

quietshout:// links plug straight into the Shortcuts app for Home Screen icons, Back Tap triggers and full automations.

Two unmissable display modes

Flash Mode fills the screen with giant words, one at a time, readable across a stadium. Marquee Mode scrolls silky-smooth full-height letters like a genuine LED sign.

Maximum brightness, automatically

The screen stays awake and blazes at full brightness for as long as your message runs, then quietly returns to normal.

Built for a long night

Save unlimited prompts, group them into custom categories, and swipe right to Flash or left to Scroll straight from your list. Recent shouts stay one tap away.

Total speed control

From dramatic 0.2x slow motion to rapid-fire 3.0x. Tap to freeze mid-shout and resume the instant you are ready.

Questions, answered.

Does Quiet Shout need an internet connection?

No. Every shout is rendered on your device. It works in airplane mode, in a basement venue, and anywhere with no signal at all.

Can I read it from far away?

That is the point. Flash Mode shows one giant word at a time filling the entire screen, and the display is driven to maximum brightness automatically while a message runs.

Do I have to rotate my phone?

Never. Hold the iPhone upright and your message runs the full length of the screen, banner-style. No rotating, no waiting.

Can I trigger a shout without opening the app?

Yes — through Siri, the Home Screen widget, or a quietshout:// link wired into Shortcuts, Back Tap, or any automation you like.

Your voice has limits. Your screen doesn't.
