Dotlumo
An Android app that turns a phone into a bright scrolling LED sign — type a message, tap, and hold it up at a concert, the airport or a shop window.
What it does
Type it, tap it, hold it up.
- 01
A real LED look
A true dot-matrix display drawn on the GPU, or big glowing text. Colours, gradients, blink, mirror, a clock and timers, in 14 languages.
- 02
The show comes first
No ads while a sign is playing, ever. It turns to landscape by itself, keeps the screen on, and can be locked against stray touches.
- 03
No account, no subscription
Works offline and your messages never leave the phone. Pro is a one-time purchase that removes the ads and adds 1080p video and GIF export.
