You know that person. Phone blazing in a dark cinema. Ringtone cutting through a piano concerto. Flash firing at a concert. Don't be that person. Blackout is a single-tap utility that does three things the moment you activate it: Dims down your screen brightness, silences your volume to zero, and locks your camera flash permanently off within the in-app camera. No settings to dig through. No toggles to remember. Just tap, and disappear into the dark. What Blackout does: Screen blackout. No blinding brightness in the dark, no light pollution for the people around you. Volume zero. Drops to silent instantly. No surprise notifications, no accidental sounds, no embarrassing ringtones mid-performance. Flash locked off. Built-in camera keeps flash disabled permanently. Shoot the moment freely without blinding anyone around you. Made for: Concerts, live music, classical performances, theatres, cinemas, comedy shows, sports events, opera, ballet, lectures, religious services, anywhere you need to be invisible. One tap. That's it.
