Watch LED Scroller turns your Android phone and Wear OS watch into LED message boards. Write a cheer, name or short message, then choose how it moves, looks and reacts to touch.
Use a single screen for an event or silent conversation, or connect several phones into a shared billboard. Presets, widgets, setting links and a compatible watch-face complication keep your favorite messages easy to reuse.
Key features
- Scroll, Static and Character modes on phone and Wear OS.
- 14 fonts, custom text colors and separate 1–10 size and speed controls.
- Touch effects, five presets and two phone widget options.
- Connected Billboard rooms and shareable settings.
Three ways to display your message
Scroll moves the text across the display; Static keeps a phrase on screen; Character shows one large character at a time. Choose the mode that suits a long cheer, a short label or a bold sequence.
Character mode centers each character within the watch screen and uses its own transition speed. Static does not use scroll speed or direction; preview the phrase and select a readable size for your device.
Make the text your own
Choose from 14 fonts, color presets including gradients, and dark background colors. The custom color picker also lets you select your own solid text color rather than relying on presets.
Font names are shown in their own typeface. Step through fonts with the arrows or tap the name to open the complete list; text size has a separate 1–10 slider.
Control motion and orientation
Adjust scrolling speed with a 1–10 slider independently of text size. Choose the direction and rotate the display through 0°, 90°, 180° or 270° to suit the way you hold the device.
Blinking has its own speed setting and can be switched off; a dot effect adds an LED-style texture. Use a slower pace for longer phrases so each part remains readable.
Add a response to touch
Tap the LED display on your phone or watch for vibration and a visual effect. Choose glitch, flash or pulse to add a brief accent while the message is displayed.
The effect is configurable and can be disabled in settings. Keep a simple display for a practical message, or add an effect when you want a more playful banner.
Display on a phone or Wear OS watch
The mobile app supports fullscreen LED playback as well as editing and preview. Use the phone as a larger sign, including on a tablet where scrolling text adapts to the screen.
Install the Wear OS app separately to show the message on your wrist. Phone settings are sent to the paired watch; if an update does not appear, check the connection and open the watch app.
Keep favorite messages close with widgets
The quick-launch home widget lets you browse presets 1–5 with left and right arrows. Press Play to open fullscreen playback, or tap the preview to open the app.
The resizable LED display widget shows a static preview of your current setting and updates when that setting changes. Use it as a home-screen message rather than an animated scrolling widget.
Connect phones into one billboard
Create a Connected Billboard room and give friends the room key. Continuous mode carries the text across phones placed side by side; Mirror mode shows the same message on every screen.
The host controls device order and the room mode. Playback and blink timing stay coordinated even across different screen sizes or different play-button times, and the room remains joined until you leave it. Connected Billboard does not support Character mode.
Share a complete LED setting
Share your message and its visual settings by link so another person can import the same configuration. The share dialog displays the URL and key, with options to copy or share the URL.
Sharing the same unchanged setting reopens its existing dialog rather than creating another key. Sharing and importing require a network connection; use a preset to keep a favorite setting readily available.
Put a message on a compatible watch face
Watch LED Scroller provides a static message preview as an image complication. Choose it as the complication source on a watch face that supports a photo or image slot.
LED Board Watch Face is a related option for keeping your message on the watch face. The complication is an image preview; fullscreen animated playback is provided by the Scroller app.

Updates
- Release highlights: Choose Scroll, Static, or Character display modes. Character shows one large character at a time, centered within the watch screen. The final onboarding screen opens the detailed product page.
- Release highlights: Tap the phone or watch LED screen for vibration and glitch, flash, or pulse effects; choose an effect or turn it off in settings. Font names preview their typeface, with previous/next arrows and a full list. Text scales better on large screens, and size now has 10 slider levels.
- Localized Connected Billboard: The friend-connection screen now shows its guidance text, buttons, and room info in each supported language.
- Faster Static Text: When scrolling is off, static text now appears on the watch much faster than before.

- Custom Text Color: Pick any solid text color with the color picker while keeping the existing preset colors available.
- Connect with Friends: Join several phones in one room and scroll the same LED together. Line phones up for one long continuous billboard, or use mirror mode to show the same message on every screen. Create a room, share the room key, and everyone stays in sync automatically — even across different screen sizes.
