How to use it
- Pick a color. Choose a preset from the row above, or use the custom color picker for any shade you want.
- Set the brightness. The slider goes from a barely-there glow to a usable lamp-level light.
- Turn on color cycle (optional). The glow drifts smoothly through the spectrum — calming for some people, distracting for others.
- Choose a sleep timer (optional). The glow will fade out gracefully after the time you pick.
- Go fullscreen for the real nightlight experience. The entire screen becomes the glow, and a small control bar lets you exit when you want.
Tips for the best nightlight effect
- Lower your screen brightness. Most screens are far too bright at maximum. Drop your device's brightness to 20–40% before going fullscreen.
- Use warm colors at night. Red, amber, and warm white are gentlest on melatonin. See our colors guide for the full breakdown.
- Place the screen face-down or angled away. The light reflects off the ceiling or wall for ambient illumination without the screen directly in your eyes.
- Keep the device plugged in if you're running it for the whole night.
