Guardian Screen Lock sits invisibly over your game or other app, locking and dimming the screen to block accidental touches and preserve battery life.

But doesn't Android already do this? No, it does not. Some phone OEM's have custom utilities (such as Samsung Game Booster), but these are manufacturer-specific, not part of Android itself and therefore not available to other phone models. Guardian Screen Lock works on anything.
