Dotlumo: LED Banner Scroller

Turn your phone into a bright scrolling LED sign. Type a message, tap the preview and hold it up: at a concert, at the airport, in a shop window or across a noisy room. THE SHOW COMES FIRST • No ads while your sign is playing. Ever. In the free version ads stay in the editor: a small banner, and at most one full-screen ad after a video export. • No weekly subscription. Pro is a one-time purchase, yours for life. • Works offline. No account, no sign-up. A REAL LED LOOK • A true dot-matrix display drawn on the GPU: smooth scrolling, sharp at any size. • Or the classic style: big glowing text in your phone's font. • Choose text and background colors, glow, size and the visibility of unlit LEDs. • Colors your way: rainbow, gradients, a slow color cycle, a color per word, outline, neon, shadow and 16 one-tap themes. • Scroll left, scroll right or keep it still; set the reading speed from slow to very fast. • Light effects: blink (never faster than 2.5 flashes a second), fade or breathe; and mirror mode so it reads correctly through a car or shop window. • Scroll endlessly, once, 2 to 10 times, or back and forth. • Up to 3 lines, aligned left, center or right, top, middle or bottom. MADE FOR HOLDING UP • The show turns to landscape by itself, uses the brightness you choose and keeps the screen on. • An optional 3-2-1 countdown gives you time to turn the phone around. • Tap for brightness, pause, lock and exit. A locked show ignores stray touches; press and hold to unlock. • Swipe to the next or previous favorite without leaving the show. • Long shows: when the phone gets hot or the battery is low, the show turns its glow off and dims itself. CLOCK, TIMERS AND LIGHTS • Clock, countdown, countdown to a date or stopwatch, in your sign's own look. • Shop kit: OPEN with the time, an opening countdown, BACK IN 5 MINUTES. • Concert kit: light sticks in any color, steady or breathing. • Word by word: one word at a time, as large as the screen allows. YOUR SIGNS, SAVED • Save favorites with their colors and style, rename, duplicate and reorder them. • Playlists: put signs in order, each for its own time, and step through them in the show. • History keeps the last 100 signs you showed. Turn it off any time; it is stored only on your phone. • Ready-made templates for the airport, concerts, birthdays, shops and more, in English, Turkish, Persian and Arabic. TALK WITHOUT SPEAKING • Communication mode: type or pick a quick phrase, show it full screen, turn it to the person opposite and have it read aloud. Nothing typed there is saved. SHARE AS A VIDEO OR IMAGE • Turn your sign into an MP4 video (tall, square or wide, 5 to 60 seconds) or a still image for WhatsApp, Instagram or TikTok. Made on your phone; saved without any permission. LANGUAGES • Turkish is spelled right, including İ, Ş and Ğ on the LED display. • Persian, Arabic and Hebrew display correctly, right to left, with joined letters on the LED dots too; Russian and Greek as well. • The app speaks 14 languages, from English, Spanish and Portuguese to Russian, Indonesian and Vietnamese. PRO (ONE-TIME) • No ads, now and in any ad format added later. • LED look pack: square and diamond dots, dot size, unlit LED color. • Your own gradients: 2 to 5 colors, for text and background. • Videos in 1080p and 60 fps without the small logo, and GIF export. • Playlists that play by themselves: signs in order, each for its own time, on a loop. • All future on-device Pro features. • Try the Pro look in the editor before you buy. Light sensitivity: blinking stays below 2.5 flashes a second, but flashing or color-changing light can still affect people with photosensitive epilepsy. Turn the effect off if it bothers you. Privacy: no account, and your messages never leave your phone. The free version shows ads from Google AdMob; you can review your ad privacy choices in the app where the law requires it.
