For me, it's a tool to track my time i'm spending on which projects.
How do you track time that you spend on the project that is not done inside the editor; for example research?
As a proper Emacs user I also do my e-mailing there and my e-mail is in a git repository. Whenever I feel like I haven't got much done in a day I can usually verify that I it was because I spend like half a day writing e-mails instead of coding.
One of the more surprising stats I have found out about myself is that I regulary spend about 5% project time writing git commit messages.
I actually find the most value of wakatime that I can keep track of that I don't work too much on the "wrong" projects. Wakatime has helped me hold off things I should not focus on that much.
Wakatime has at least somewhat reduced my imposter syndrome tendencies because I can use it to disprove the feeling that I'm not getting things done because it tells me that I got things done even if it was not the things I originally had plan to get done.
