My friend Nicholas Felton (of the Annual Feltron Report fame) has finally produced the iPhone app for Daytum. It allows you to quickly and easily track anything you’d want about your life. For example, most people have no idea how much food and drinks they consume in a week. You have to manually enter the information, but it’d be good to actually know how much booze you drink on a weekly basis. And of course it’s beautiful, Nicholas designed it. 

I encourage you all to pick one thing about your life you want to track and do it for a week. Your findings may surprise you.
