Screen On/Off Aid play online

The idea to search for, and later to create this app came from two main motives.
The first was that when I used my first Android phone for a longer time (and others before) the physical keys gave up after a while,
so their usage should be minimized: on current phones it is the power button. (How many times a day You check for the time?)
This might be similar with the display-tapping screen on functionality - wears the touch screen. Power-wise, the face recognition might consume more as it runs the camera, and analyzes its image.
The next use-case happens when I read an article or book where the actual page needs more time to be absorbed, and the app in question does not have keep-alive functionality.
I was looking at apps from the store, but neither was doing what I needed, or not the way I wanted it, so this came alive.
