Apploye calculates Active and Neutral time based on activity percentage. Activity is calculated based on the mouse clicking/movement and keyboard pressing.

If there is no mouse or keyboard movement, that'd be considered Neutral time. If there is activity, it'd be considered Active time.

In Apploye, the Productive time is called "Active" time, and the Non-Productive time is called "Neutral" time.
