I already found this app which is not really doing what I want, because it is for games and I don't want to see my cpu usage.
I am specifically searching for this app.
I tried to find but I didn't. So if somebody knows it it would be pretty great if not here is what I am searching for:
A software which tracks which programs I use for how long, has a categorizing feature and shows me my usage.
So basically a one which does what was in the video I linked up on "this app".
Trying to find a software just gave me "spyware" and "company monitoring" apps like for a network which not match my criteria.
