The Circle

Indicates the percentage of the allowed screentime used

The Color

Shows the ratio between the passage of time and the usage of the screen.

Defined like that:

correctUsageIndicator = Percentage of screentime used / percentage of day passed

correctUsageIndicator < 1 - Green

correctUsageIndicator > 1 - Red

correctUsageIndicator == 1 - Orange

The color will be orange also if the value is close to 1 but not exactly one.

The rest is clear IMO
