전광판 - LED 응원 문구, 콘서트

There are times when you want to send a message to your favorite singer during the final song of a concert. This app transforms your phone screen into a full-screen LED display that fills the entire width.

When you enter a message, large text flows across the screen, and you can choose between flowing and stationary modes. With five speed levels, you can also enable blinking and rainbow color cycles to ensure visibility in the dark auditorium. You can customize the text color, background color, and font size to your liking. Your last entered message and settings are saved, so they appear exactly as they are the next time you open the app.

• Horizontal full-screen display

• Two modes: flowing and stationary

• Five speed levels and blinking

• Rainbow color cycle and color/size adjustment

The screen does not turn off while running, keeping the display bright throughout your cheering session. It does not require separate permissions and operates without an internet connection, so you can use it immediately after installation.
