I'm a fan of ManicTime on Windows. It does a great job of tracking how much time each app is active (i.e., has focus). I have rules set up so that it aggregates the time I spend with things like a terminal or IDE open as "work" time and things like VLC as "fun" time. It also has the ability to track which web pages are being viewed while the browser is active, but I haven't figured out a good way of classifying work pages versus fun pages.
