Concert sign app: a fan banner on your phone
No printer, no cardboard, no glitter. Type the name or the lyric line, pick a color that matches the fandom, and hold up your phone — Screaming Screen makes it a glowing sign readable from the back rows.
How to make a concert sign on your phone
- Type the message — a name, a lyric, an inside joke. Hangul, kana, Cyrillic and emoji all work.
- Pick the fandom color for the text and black for the background: it reads best under stage lighting.
- Choose a font: Lobster for a handwritten sign, Russo One or Oswald for maximum legibility.
- Optional: Blink or Scrolling animation, or an attention flash every few seconds.
- Tap FULL SCREEN, hold the phone sideways and raise it. Tap anywhere to exit.
Made for K-pop and fan culture
Screaming Screen works as a K-pop fan banner, a slogan board or a cheering sign. Attention effects — a white burst, TV static, a brightness blink or a red flash every 3–10 seconds — help catch an idol's eye during a fan-cam moment. The rainbow animation cycles through colors, and the giant auto-scaling text uses every pixel of the screen.
Venue-friendly
Many venues ban printed banners above a certain size or anything on a stick; a phone is always allowed. Max brightness is made for arenas; in a small club you can switch it off and keep your own brightness. A three-hour show at full brightness is a real battery workout — bring a power bank.
Free to try
Static signs are free without limits. Animated effects, premium fonts and flashes give you 5 full runs, then 15-second demos; a one-time PRO purchase removes the timer forever. No ads, no account, works offline in the venue with no signal.
