About this app

Make your phone a full-screen LED sign with FLOW SIGN. Create scrolling text banners for concerts, airport pickups, sports, parties and everyday messages—without printing a sign.

Type your message, choose a style and start your display. The clean editor gives you control over text color, background color and motion in just a few taps.

**Make your message stand out**

• Full-screen text display: Show large, easy-to-read words across your phone screen.

• Scrolling text: Move messages left, right, up or down, or keep them still. Adjust speed and text size.

• Custom colors: Change text and background colors together, or choose a gradient style.

• Blinking effects: Choose soft, fast or strong blinking. Add glow, wave and LED-style effects.

• Message mix: Combine multiple messages and create crossing text movements.

• Quick presets: Start with styles for concerts, airport greetings and events.

• English and Korean: Switch the app interface to the language you prefer.

**Designed for real moments**

At a concert or fan meeting, hold up a cheering message. At the airport, display a name as a pickup sign. At sports games, birthdays, festivals or store events, turn a short message into a moving digital banner.

No account is required. Your messages and style settings are stored on your device. Ads appear in the editor, not on the full-screen sign.

FLOW SIGN — make your message easy to see.
