NightShield: Blue Light Filter

About this app

NightShield is a lightweight, privacy-first eye-care toolkit that sits quietly on your phone and steps in when the sun goes down.

One tap gives you a warm, adjustable tint that filters harsh blue light. Another dims your screen below the system minimum so late-night reading doesn't sear your eyes. A third gives you a gorgeous Always-On Display — clock, date and battery — so you don't have to wake the whole screen just to check the time.

Everything runs as a tiny overlay — no screen recording, no root, no ads that hijack your scroll. No login. No tracking. Your schedule, your settings, your phone.
