Screen Glow: LED Banner & Sign

Your phone is the stage.

Screen Glow turns your phone screen into a portable light device — an LED banner, a glowing stick, a scrolling text sign, a night lamp, a strobe light. No extra hardware to buy, nothing extra to carry. Open the app and the light is on.

LED Banner & Scrolling Text
Type any message and watch it scroll across your screen like a real LED sign. Set the color, the size and the speed. Switch between horizontal and vertical so it reads right whether you hold the phone upright or sideways — a support banner at a concert, a sign on a shop counter, a name plate at a party.

Glow Stick & Concert Mode
Turn your screen into a glowing wand that breathes, waves or flashes to the rhythm. Pick one of dozens of glow presets or build your own from scratch. Made for concerts, festivals, parties and clubs.

Multi-Phone Sync — Light Up As One
This is what makes Screen Glow different from a simple flashlight app. Connect several phones over your local Wi-Fi — no internet needed, no account, no pairing headache — and drive them all from one host. Friends join by scanning, and every screen pulses in perfect sync. Form a light formation at a concert, line up a row of phones as one wide banner, or drive a whole wall of screens at once.

LED Art Wall & Video Wall
Split a single photo or video across several phones and watch them line up into one large picture. Turn a drawer full of old phones into a video wall.

Everyday Lights
- Night light: soft, warm or colored, with your own music playing along.
- Breathing and relaxation light: a slow pulsing glow to wind down before sleep.
- Fill light: bright, even screen light for selfies, video calls and streaming.
- Flashlight and strobe: a steady beam for walking at night, or fast flash patterns for parties.

Save, Export And Share
Save your favorite setups and bring them back in one tap. Export your effect as an animated GIF. Or generate a poster and send it to a friend — when they open the link, the same light comes back.

Private By Design
Everything runs on your phone. No account, no sign-up. Multi-phone sync talks over your local Wi-Fi only — your photos and messages never leave the device.

No Extra Hardware
A printed banner or a real LED sign does one thing, and only one thing. Screen Glow does all of it on the phone already in your pocket.
