Smartphone LED banner app
HELLO LED
Your phone into an LED banner
An LED sign you finish on your phone. Show concert cheers, airport pickups, and shop notices in large type. Fonts keep being added, and you can set the colors, scroll, and glow the way you want.
Start on your phone, with no equipment
No heavy sign and no display gear.
Use it at a concert, at the airport, or as a shop's digital sign.
A paper-free airport pickup board
Fill the phone screen with a name and a welcome. Greet them with a clean digital pickup board instead of a paper sign.
A shop LED sign that draws people in
Use the phone for a sale, opening hours, or an order number. Scroll the lines that should stand out, such as OPEN and SALE.
A message for a day that matters
Show a birthday wish, a confession, exam support, or a welcome. Eight presets, including birthday, cheers, love, and thanks, are ready when you need them.
More than a sign
Custom text is the start. Add an LED clock, a D-day countdown, a timer, and photo-to-dot art.
A design that matches your taste
From neon color to flicker
Five neon colors, a custom color, and a range of fonts. Set the size, brightness, and speed, and add flicker and glow.
App screen: landscape text with color and font
Easy to read from far away, and it stays on
Type that fills the screen
Turn it sideways and the whole screen becomes an LED sign. It stays readable from a distance, and the screen does not turn off while you use it.
Clock, D-day, and timer in LED
Time, shown large
Show the time, a countdown, or a timer in clear LED digits. It helps at an event or while people wait at a shop.
App screen: a clock on the landscape sign
Photos as LED dot art
Converted on the device
