Blue Light Filter & Dimmer

Screen Filter reduces blue light and makes your screen even darker to ease eye strain. It overlays a soft color filter on top of your screen, letting you dim below the system's minimum brightness: perfect for dark rooms or right before bed when the screen feels too bright. An overly bright screen at night can get in the way of winding down: switch to night mode for a glare-free evening. ■ Key features • Blue light filter: cut the blue tint to reduce eye strain and glare • Extra dim (ultra dim): go darker than the system's minimum brightness, ideal for night use • Sunset-to-sunrise mode: turns on at sunset and off at sunrise automatically (no location permission needed) • Bedtime schedule: or set your own custom on/off times • Fine-grained control: adjust filter strength and dim level with separate sliders • Filter colors: Amber, Orange, Sunset, Candle, Sepia, Classic • Light & dark mode: dark by default, switch to light anytime in settings • Home screen widget: toggle with one tap (Material You colors) • Quick Settings tile & notification button: control it instantly without opening the app • Works over other apps: the filter stays on while you use any app • Lightweight: a simple, fast design that's easy on the battery ■ Great for • Anyone who uses their phone at night • People whose screen is too bright even at minimum brightness • Those who want to reduce eye fatigue from blue light ■ Permissions • "Display over other apps" is required to overlay the filter across the whole screen. • While the filter is on, button input may be blocked on some system screens such as app installs, permission grants, and payments: please turn the filter off for those screens.
