This gorgeous companion to the Daytum website lets you log your life as obsessively as a baseball statistician. How much coffee did you consume last year? Number of books read? Miles run? Turn it into graphs for a snapshot of what it's like to be you.
WIRED Makes your life seem cooler than it actually is. (Even bad habits look nice as graphs.)
TIRED Advanced data logging requires paid membership ($4/month). No way to log how much time you waste logging everything you do.
