Complice is a paid service. If you aren't desperate to cowork the effective altruism videochatroom or lesswrong equivelant, try tracking time which is free and more professional instead.

The reason though, that I prefer complice is the ontology. I have to categorise my tasks. What counts as workflow integration, what counts of inbox zero, and what as to the content of that email: e.g. acting on a newsletter from my daughter's swim pool place to do something? It's not compatible with the Mckinsey MECE ontology that I prefer. Meanwhile, complice is super expensive and the free version doesn't let me save my goals so they're lost forever. Manually tracking in excel gets really cluttered, too.
