Charm - the Cross-Platform Time Tracker Windows Build status

Whether you are a busy professional who needs to keep track time spent on projects or a student who wants to plan their studies: knowing how your time is spent is a good idea.

Charm is a program for OS X, Linux and Windows that helps to keep track of time. It is built around two major ideas - tasks and events. Tasks are the things time is spend on, repeatedly. For example, ironing laundry is a task. The laundry done for two hours on last Tuesday is an event in that task. When doing laundry multiple times, the events will be accumulated, and can later be printed in activity reports or weekly time sheets. So in case laundry would be done for three hours on Wednesday again, the activity report for the "Ironing Laundry" task would list the event on tuesday, the event on wednesday and a total of five hours.


By default, the list of tasks known to Charm is empty. They have to be created manually. So the first time work is done on a task, the task entry needs to be created in the task list. Then, by selecting a task and starting it, time will be recorded on that task. A comment can be added that may help to identify later what the individual event was for. Switching from one task to another is a matter of starting the other task.

Tasks can have subtasks, and create a hierarchy this way. It is recommended to create rather few top level tasks, since tasks are also used to group in reports. Other tasks can then be created as children or even grandchildren of the top level tasks.


Every time time is recorded for a task, an event is created. What events exist can be seen in the event editor (View->Event Editor). Also, new events can be created there (without recording them), modified or deleted.


Activity Reports

Activity Reports group all events that happened in a certain time frame, like a day or a week. They are handy to get an overview of what was worked on during that time.

Time Sheets

Time Sheets are created per week, and group event time to tasks and week days. Time Sheets are great to report to the boss, you see.


For released versions, binary packages are available:

For various Linux distributions, packages are available via the openSUSE Build Service.

For Windows and OS X, find installers here.
