Nice time counter. Recommended

Tmetric do a gread job, even in the free version

Unclear how you actually manage to integrate this with Teamwork. Under the integrations documentation for teamwork, it just links to the firefox addon page.

Works with redmine, youtrack, google keep

Cant seem to figure out how to use this tool. I like the idea, but it won't integrate with Todoist which is my fav project manager. I am currently trying the Business Subscription which supposedly supports Todoist integration, but there is no obvious method to create or set any timers to todoist even though I have a todoist Firefox extension which I use. I've tried to contact the support team with TMetric, but they have not responded to my support requests. You would expect a company which depends on support revenue to be responsive to support requests!!

Works well, helps a lot with time tracking.

Disabling 3rd party cookies will make this extension stop working.

I love this tool.
