Lumitron: Fullscreen Clock

Lumitron turns any screen into a full-screen retro clock - and nothing else.

No status bar. No navigation buttons. No browser address bar, no home indicator, no window frame, no menu. Open Lumitron and the only thing left on your screen is the time.

EIGHT REAL DISPLAY TECHNOLOGIES
Every theme recreates the physics of an actual historic display, not just a different font color:

- LCD - familiar liquid-crystal segments, including the classic grey-green look
- LED - vintage red glow, plus white, green, amber and blue variants
- CRT - cathode-ray tube look with soft glow and scanlines
- VFD - vacuum fluorescent display with its signature blue-green light
- Nixie - neon glow-discharge tubes in warm orange-red
- Panaplex - flat neon seven-segment displays
- Numitron - incandescent filament digits, steady warm light, no flicker
- Electroluminescent (EL) - glowing teal EL panel

AUTHENTIC PHYSICAL EFFECTS
Glow, bloom, ghost segments, fine scan lines and vignette, segment grids, gentle flicker - each effect recreated for the technology it belongs to, and each one can be switched on or off.

MAKE IT YOURS
- Color variants within every display technology
- 12-hour or 24-hour format
- Show or hide seconds
- Adjustable digit size, from compact to full screen
- Thin, regular or bold weight
- Authentic seven-segment DSEG7 font

TIME, YOUR WAY
- System time - accurate, always in sync
- Custom time - set any hour, minute and second
- Frozen time - lock the display at a chosen moment, perfect for photos or a shop window display

ALWAYS ON
While Lumitron is open, the screen stays awake - no dimming, no sleep. Leave it running as a bedside clock, a desk display, or a second-screen companion.

LEARN AS YOU LOOK
Each display technology comes with a short explanation of how it works and why it looks the way it does.

ONE TAP, NOTHING ELSE
Settings open with a single tap anywhere on screen, and close the same way. In normal view there isn't a single button visible - just the clock.

Lumitron is exactly what it looks like: a clock. There's no alarm, no timer and no date - just an honest, true full-screen digital clock built around eight real display technologies.
