Quick answer
A dim, night-vision-friendly screen light with swipe controls
gloomy turns the whole screen into a single, very dim color. It is meant for finding your way in
the dark without disturbing your night vision or raising your vigilance, e.g., checking on a
sleeping child without blinding yourself or anyone else, or getting a glass of water at night.
Controls
- Swipe up or down, or use the volume keys, to make the light brighter or dimmer.
- Swipe left or right to move continuously from red through amber and yellow to white.
- Red by default, which preserves night vision best.
- Goes dimmer than the phone's lowest brightness setting by also dimming the color itself.
- Keeps the screen on and hides the status and navigation bars while open.
- Quick settings tile that opens gloomy straight from the lock screen, without unlocking the phone.
- Remembers the last color and brightness.
- Changes the screen brightness only while gloomy is open.
- No permissions, no network access, no ads, no tracking.
