Night Shield lays a warm filter over your whole screen to cut blue light and glare after dark. One tap to switch it on, and it works over every app.
Start from one of nine presets, from deep red to a cool tint, or pick the exact shade on a color wheel with a live preview. Then set how strong it is.
Save filter setups as profiles and switch between them in one tap, or start from the built-in ones. A sleep timer turns the filter off once you've drifted off.
Set the times the filter comes on and goes off, and it handles the rest, even after a restart. With Pro it can follow sunset and sunrise where you live.
Pause the filter in the apps where true color matters, like the camera, maps or a photo editor, or give an app its own intensity. Night Shield switches as you move between apps.
Seven app themes, including true-black OLED and Material You, and home-screen widgets in three styles: standard, minimal and detailed.
Drive the filter from Tasker, Shortcuts or Bixby, back every setting up to a file, and see how much screen time you spent filtered each week.
The filter, presets, dimming, a schedule, the sleep timer and eye-break reminders are free, with ads. Night Shield Pro is a one-time purchase through Google Play that removes ads and unlocks every feature. You can also try Pro features free for 24 hours by watching a short ad.

Night Shield has no account and no analytics, and your settings stay on your phone. The Accessibility service is used only to detect which app is open for your per-app rules; it never reads what's on screen. Location is used only for sunset and sunrise times, and only if you turn that on.
Read the privacy policyBlue light in the evening can suppress melatonin, the hormone that makes you sleepy. A warm filter cuts the blue light your screen gives off and eases glare in a dark room, which many people find more comfortable at night.
Yes. The filter, all nine presets, custom colors, dimming, one schedule, one per-app rule, the sleep timer and eye-break reminders are free, with ads. Night Shield Pro is a one-time purchase that removes ads and unlocks everything else. No subscription.
Yes. Screen dimming darkens the display beyond your phone's own minimum brightness, which helps in a completely dark room.
Only for per-app rules: it tells Night Shield which app is in the foreground so the filter can pause or change. It does not read or collect screen content, and the rest of the app works without it.
Yes, with Night Shield Pro. It uses your approximate location to work out local sunset and sunrise times. You can also set fixed on and off times instead.
A static overlay uses very little power. Sensors such as the accelerometer for shake to toggle, or the light sensor for adaptive intensity, only run while you have those features turned on.
Phones and tablets running Android 10 or newer.
Easier on your eyes after dark.
