Scrolling LED text, light stick & arrival signs for concerts, airports & parties
Turn your phone into a bright LED sign in seconds. Type a message, pick a style and hold it up. It reads clearly from the back of a concert crowd, across an airport arrivals hall or from the far end of a party. Glowboard works fully offline. No account, no sign-up, and your messages stay on your phone. ★ SCROLLING LED TEXT • Real LED dot-matrix look with a soft glow • Scroll left or right, or keep the text still • Adjust speed, size, letter spacing and blink • Mirror mode for reading through a car window • Two-line text, outline and drop shadow • Live preview while you edit ★ LIGHT STICK MODE • Fill the whole screen with one bright color • Solid, pulse, strobe and rainbow effects • Beat sync: flash in time with the music using your microphone.
