Big Big Big: Bigger, Biggest

A few words. Impossible to miss.

Big Big Big turns your iPhone or iPad into a bold, readable sign. Write a message, choose its look, and tap the preview to fill the screen.

MAKE YOUR WORDS BIG
Text fits the available space with natural wrapping, four typefaces, and support for emoji and international scripts. Use Still for a complete sign, Scroll for continuous movement, or Marquee to move left, pause, return, pause, and repeat. Adjust speed, mirror the lettering, and pause or resume with a tap.

FIND YOUR COLOR
Choose from 54 themes, including rainbow lettering on solid backgrounds. Pick custom colors or save your own themes.

KEEP THE RIGHT WORDS READY
Save messages, mark favorites, search, filter, and sort your library. Organize messages into ordered collections, swipe between them full screen, or run a slideshow. Each saved message can keep its own look.

SHARE AND BACK UP
Export crisp PNG signs in square, portrait, or landscape formats. Back up your whole library or a single collection in Files, then review and merge imports without multiplying duplicates.

READY WHEN YOU NEED IT
Use widgets, Siri and Shortcuts, or share selected text from another app. Optional presentation lock helps prevent accidental exits. Keep the screen awake and optionally boost brightness while displaying a sign.

FREE TO USE
All features are included. Optional, repeatable tips support development and do not unlock features. No subscriptions, account, ads, or tracking. Message creation and display work offline. Your messages stay on your device unless you choose to export or share them.

Designed for iPhone and iPad, in portrait and landscape. Requires iOS or iPadOS 17 or later.
