Fwiw, I developed a very puristic similar project: https://github.com/albertz/timecapture https://github.com/albertz/timecapture So far, it's only tracking the time and recording which app is in the foreground and what file / url is currently opened in there. It doesn't have any GUI and it won't show you nice statistics like Qbserve. But it shouldn't be difficult to calculate any statistics you want from the data. Python, Open Source, easy to add support for other platforms and apps (so far mostly MacOSX support). Patches are welcome. :)
