JumboCheer: LED Cheer Board

About JumboCheer: LED Cheer Board

Line up your phones and they become one big scrolling LED board.

One phone works on its own. Line up two, three or four and a single message flows across all of them as if they were one long display.

■ No Wi-Fi required
Phones connect to each other directly over Bluetooth. It works in a packed arena where the network is congested, or anywhere with no Wi-Fi at all. No account, no sign-up.

■ Different phone models still line up
Text is laid out using the real physical size of each screen in millimetres, so letters stay the same height and move at the same speed even when the phones are different sizes.

■ From one phone to four
One phone is a sign you can hold. Two are already eye-catching. The more friends join, the longer your board gets.

■ Choose your colours, speed and font
Set the text colour, the background, the scrolling speed and the typeface. Or pick a ready-made look - Flame, Neon, Signboard - in one tap. Match your team.

■ Choose how it moves
Scroll it, hold it still, make it wave, slide it up from below. The same words read differently.

■ Everyone joins in
Tap the screen on a joined phone and a burst runs across the whole board - confetti, sparkles, fireworks, a party popper. The moment your team scores.

How to use
1. One phone taps "Be the host", everyone else taps "Join"
2. Scan the QR code on the host's screen (or type the number shown, if scanning is awkward)
3. Type your message, line the phones up and hold them high

Before you use it
・Messages are sent directly between phones. Nothing is stored on a server.
・Some venues have rules about bringing in lights or banners. Please check in advance.
・A brighter screen stands out more, but uses more battery.
