Twinkle Board - LED Banner

Twinkle Board turns your phone into an instant LED display board.

Type a message and it's shown full-screen in a scrolling LED dot-matrix style, big and bold. Perfect for concert and sports cheering, airport or station pickup signs, showing a quick message to someone next to you in a loud place, or a mini promo board for your shop — for any moment when you need letters that read from far away, right now.
