I know such applications exist, but I'm not sure how they're really called. If someone could just direct me to a link to a similar question, that'd be fine.
Anyways, I'm looking for an application, that monitors how much during the day, was each application used. The problem is that some of them (firefox playing radio, visual studio always open ...) are running all the time - so I would need something to measure time during which it was actively used (for example, if firefox is running, but no mouse clicks or keyboard ticks, then put it in "passive" mode).
Is something like that available ?
Appreciate all advice on the matter.
