Big Text: Flash messages full screen
Display text giant and bright from across a room, in auto-fit or scrolling mode, with seven color themes and a smooth blink option.
Need to show a message to a large group—at a concert, airport, or classroom? Big Text fills your phone screen with huge, readable text. You type once, pick how you want it to appear (stretching to fit or scrolling like a marquee), choose a color theme, optionally add a gentle fade-in-fade-out blink, then tap Flash It to display it full screen.
What it does
The app opens with a message editor where you type up to 120 characters. You choose between auto-fit mode, which scales the text to fill the screen, or marquee mode, which scrolls it horizontally. Seven color themes let you pick combinations like classic black-and-white, hot pink, electric blue, lime, sunset orange, inverted, or violet. A gentle blink toggle adds a slow, smooth fade (not a strobe) safe for photosensitive viewers. Press Flash It and the screen goes full, hiding all controls—tap anywhere to return to editing.
