Type it. Flash it.
SCREAM IT.
Your phone is the loudest sign in the room. Type a message, hit FULL SCREEN — and the screen turns into a glowing banner at maximum brightness that never goes to sleep.
- 🎤 Concerts & shows — cheer your idol from row Z
- ✈️ Airport pickups — a name sign that can't be missed
- 🎉 Parties, dates, pranks — say it in 400-point type
Everything an LED banner app needs
🔆 Max brightness
One tap pushes brightness to 100% and keeps the screen awake. Exit — and your settings come right back.
🎬 Motion that grabs eyes
Scrolling marquee, blink, pulse and rainbow — smooth animations that read from across the street.
⚡ Attention flashes
Periodic white bursts, TV static, brightness blinks or red alerts every 3–10 seconds. Impossible to ignore.
🔤 Fonts with character
From pixel-arcade to elegant script — five display typefaces with Cyrillic and Latin support.
🌍 Speaks your language
Interface in 10 languages. Message in any language or emoji you like. Works fully offline.
🎲 Feeling lucky?
The dice button rolls a fresh style — colors, animation and font — with readable contrast guaranteed.
Screaming Screen is a free LED banner app and LED scroller for iPhone and Android. Use it as a scrolling text marquee, a concert sign or K-pop fan banner, an airport name board or a party message — no printing, no extra hardware, just your phone screen.

Meet guests with a name sign that can't be missed — bigger and brighter than any printed sheet, ready in ten seconds.
🎉 Parties, dates & pranks
Confessions, birthday wishes, inside jokes: type the text, pick a flashy font and let the whole room read it.

Frequently asked questions
Does the app work offline?
Yes. Everything runs on the device: no account, no sign-in, and your text never leaves the phone.
Will the screen turn off during a show?
No. While a banner is displayed the screen stays awake and brightness goes to maximum (you can switch that off in Display settings).
Is Screaming Screen free?
Yes. All effects are free to try: you get 5 full runs with PRO effects, then they turn into 15-second demos. A one-time PRO purchase removes the time limit forever — no subscription.
Does max brightness hurt the battery?
Full brightness uses more power than usual: a long show drains the battery faster and the phone may get warm. That's normal — and max brightness can be turned off anytime.
Are the flashing effects safe?
Blinking and flashing modes may be unsafe for people with photosensitive epilepsy. If you or people around you are sensitive to flashes, keep attention effects off.
Can I write in my own language?
Yes, the banner shows any text. The interface speaks 10 languages, and the display fonts cover Latin and Cyrillic; for other scripts the system font steps in.
