We've all gone through this: you spend about eight hours a day working on the PC but at the end of the day there are still tasks waiting to be done. If only you hadn't spent so much time procrastinating! Hronos can help you prevent this situation. It tracks the time you spend on every single application, plus offering complete statistics in usage percentages. The program doesn't require installation; it just sits on your system tray and does its job without any user intervention. On the downside, we missed some configuration options and the possibility to save statistics in some way. We also would like to know what the program counts as "not working". I could be browsing personal blogs all day long and that would count just as "Firefox usage".
