About this app
Hold your phone up and be seen. Glowbar turns your screen into a real LED sign — a proper dot-matrix panel, not just big text sliding past.
Type your message, tap once, and it is on screen. No splash. No ad to sit through. No sign-in.
BUILT FOR THE MOMENT YOU ACTUALLY NEED IT
• Airport and station pickups — hold up a name that people can read across a crowded arrivals hall
• Concerts and festivals — cheer without shouting
• Sports and school events — team names, player numbers, birthdays
• Weddings, proposals, parties, protests, market stalls
• Finding someone in a crowd when a phone call will not do
A REAL LED PANEL
Every letter is rendered as a grid of individual LEDs with adjustable glow, the way a transit sign or a stadium board works. Turn the dots up for a crisp fine-pitch board or down for a chunky retro marquee.
• 12 colour schemes — amber, red, green, cyan, white, pink, blue, lime, ice, violet, sunset and a moving rainbow
• 3 modes — Scroll, Static (the whole message fitted on screen) and Blink
• Adjustable speed, dot size and glow, changeable while the banner is running
• Screen stays awake and jumps to full brightness while your sign is up
• Your last messages are remembered so a repeat pickup takes one tap
ALWAYS USES THE LONG EDGE
Glowbar measures your screen and lays the message along whichever edge is longer, so the letters are as big as the hardware allows — on a phone, a tablet or an unfolded foldable. Nothing breaks when you rotate.
ABOUT THE ADS — READ THIS BEFORE YOU INSTALL ANYTHING ELSE
We wrote these rules down and built the app around them:
• No ad when you open the app. Ever.
• No ad while your banner is on screen. Ever.
• No ad you have to wait for. If an ad is not already loaded, your sign opens immediately.
• The first three banners after install are completely ad free.
• After that, at most one full-screen ad per three banners, and never within two minutes of the last one.
• There is one small banner ad on the home screen. There is none on your sign.
EVERY FEATURE, ALWAYS UNLOCKED
Nothing is held back. Every colour, every mode and every setting is available from the moment you install, and stays that way. An optional ad removal is available inside the app for anyone who prefers a quieter screen.
NO PERMISSION PROMPT
Glowbar never asks for camera, photos, storage, contacts, location, microphone or phone access, so there is nothing to approve and nothing it can read. Your messages are stored on your device and never sent anywhere.
WORKS OFFLINE
Every feature works in airplane mode. No account, no sign-in, no server, no cloud.
Made for people who need a sign in ten seconds, not a tour of someone's ad inventory.
