- SYMMETRICAL CLOCK ensures the clock is moving only along the vertical axis for perfect symmetry yet avoiding any chances of burn in. Helping prolong the life of you screen.

Optional way to use the app is to add a blackr button in the quick tile settings in device status bar (near wifi bluetooth etc). It works seamlessly any time!

Runs great on devices like Google Pixel Samsung Galaxy Samsung Fold and Flip OnePlus and more.

App works by showing a black overlay on top of the screen and on most modern displays black pixels are turned completely off effectively turning the display off.

Simple and smart design makes it easy and convenient to use. Works best on OLED AMOLED PMOLED QD-OLED and similar display technologies that switch off any pixel displaying true black. App will still work on all displays though.

Can also be used to reduce any burn-in on screens as we change the lit pixels every minute it acts as a good screen reset in some cases (as reported by users). Can also be used like an Always on Display (AOD).

Technically it is an overlay and your phone is not sleeping while this is on. So power reduction is mostly from less or no screen usage and helpful to prevent screen burn in.

This app can be used in many scenarios like recording long videos watching YouTube Netflix Prime video etc. with screen off or streaming videos while listening to music only.

Moreover users find it quite useful in keeping screen on/off manually rather than using the lock button during frequent use.
