gloomy

A dim, night-vision-friendly screen light with swipe controls
New in version 1.1
* Quick settings tile: open gloomy from the lock screen without unlocking.
* New colors: red, amber, yellow, and white.
* Default brightness lowered to 0.15.
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.



Features

  • 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.
