## What is Letreo?

Letreo turns your iPhone into two stage tools: a real LED marquee and a concert light. Fast, good-looking, and entirely on the device — no account, no ads, no internet.

A REAL LED MARQUEE
This is not scrolling text with a filter over it. Letreo draws a dot-matrix panel dot by dot at 120 Hz, and the panel's resolution changes with the font size, the way it would on a physical sign. Six letter styles; neon, gradient, rainbow, pulse and flicker effects; direction and speed however you like them.

FULLSCREEN STAGE
One tap and the marquee takes the screen in landscape, at maximum brightness, with the display held awake. Turn the iPhone, raise your arm. And while you adjust things, the preview stays pinned at the top of the screen reacting live — you set the sign by looking at the sign, not at a menu.

SHOW MODE
Your phone becomes a party light: static, blink, strobe, rainbow, breathe, and Beat, which listens to the music through the microphone and pulses along. Ready-made presets for White, Strobe, Rainbow, Beat, Breathe and Police.

A REAL FLASH
Pick the output: screen, torch, or both. In Flash mode the iPhone's physical torch strobes on its own while you keep working the controls — something a website open in a browser simply cannot do on iOS.

MARQUEE PRESETS
Party, Sale, Urgent, Welcome and Birthday in one tap. And the app remembers your last setup for the next show.

In 10 languages. Built for concerts, parties, events, stadium stands, shop windows and airport arrivals.

Warning: Show Mode produces intense flashing lights. Use with care if you are photosensitive.
