About this app

Keep your night vision. Skip the harsh white screen.

StealthRed turns your Android phone or tablet into a red light screen and night clock built for dark environments. Adjustable red light, a clean red-on-black interface, and a night-friendly way to see what you need — without disrupting your night vision or waking anyone up.

Use it when you get up at night, read in bed, check on your baby, glance at the time, or need a discreet light source that won't strain your eyes in the dark.

RED SCREEN, READY INSTANTLY
Turn your Android into an adjustable red light panel in seconds. StealthRed keeps the experience simple, controlled, and comfortable — whether you're at home, camping, or under the stars.

PRESERVE YOUR NIGHT VISION
The red-on-black interface is designed for dark rooms, low distraction, and quick access. True red light lets your eyes stay dark-adapted — no harsh brightness, no white flash, no ruined night vision.

STEALTH MODE — FREE
StealthRed goes completely dark. Black screen, minimal OLED output, ready to light up with a single long press anywhere on the screen. No clock, no glow, just darkness until you need it.

LOCK SCREEN MODE — PREMIUM
This is the feature most red light apps are missing.
Press your power button to sleep. Press again and you're back inside StealthRed — no unlocking, no searching for the app, no bright detour between you and your red light. Pocket it dark, pull it out ready.

BUILT-IN NIGHT CLOCK
Check the time with a discreet red clock designed for bedside setups, desks, and stargazing sessions. No bright screen. No eye shock.

INCLUDED FROM THE START
The base version includes Classic and Vector clock faces, so you can start using StealthRed from your very first night with a real, useful setup.

WAKE-UP LIGHT
Set a prepared visual wake-up light before sleep. StealthRed gradually transitions from dark to brighter red with a soft visual ramp — a gentler way to wake when the app is left ready for the night.
