The raw data is also available in a table ('you used Notepad from 10:12:15 to 10:16:23'), while a summary details the length of your work session and the total amount of time you spend in each application.
Switch back to the program window at any time and a color-coded timeline shows you when your computer was being used, which applications you were running, the websites visited and the documents you were working on. There's no complicated setup involved, just launch the program, get on with your work, and ManicTime tracks what you're doing.
ManicTime is an activity tracker which monitors your computer usage, letting you know which programs you've used, when, and for how long.
