I want a simple minimalistic one page mobile app and web page.
A circle in the middle of the screen increases and decreases its size in an endless loop. The increase and decrease movements need to be synchronized on all open instances of the app/page.
The circle increases its size continuously for 4 seconds. It then starts to decrease size for the next 4 seconds.
A sound files is played when during size increase, another sound file during decrease. On the upper right a button allows to switch sounds on/off.
The number of currently open instances of the app/page is shown on the top left.
The backend allows to modify the increase/decrease period in 0.1 second steps, define the sound files, set the background color of the page and the forecolor the page elements (circle, sound button, counter).
