I needed a robust counter for my work, but none of thoses I found were good enough. So I made mine ! The features list is small, and the interface is primitive, but it works. I needed mostly a way to get the exact time of every action, the time elapsed since the last action, since the beginning, and a spreadsheet-friendly output format.
And because it is always useful, there’s a programmer-friendly integer format converter too.
The repository is on Github.
