I did not expect that simple banal thing as picking an European time tracking app would be in my case would be a quest actually.
Some apps are hosted at a US cloud.
Some apps have too much of automation and AI in simple task of time tracking.
Others do not have support of Linux.
Some apps have problem with exports - such as 0 in total row of Excel or lack of any total row.
Picked #SolidTime for now as my #timetracking app.
The break timer of Super Productivity actually reduced my "output".
