For personal life events Google Calendar. For tracking work related events (decisions, projects etc.) I use my own app Review19 - http://review19.com http://review19.com Have tried a lot of the popular options: Asana, Trello, Pivotal, Google Docs etc. Each has got its own strengths and weaknesses. My colleagues and I are distributed around the world and Review19.com really helps in non traditional tracking such as collaborative decision making.
