How many hours have you worked last month?
How many times have you done sports this week?
How much time have you assigned to your family?

You probably have all this data already in your calendars. So use it to answer your questions!

CalSum helps you to see an overview of the time you spent on your calendars.

CalSum calculates summaries for all your calendar events you have already created in the Calendar App – simple and fast. You can see summaries for relative time frames like today, last week, this month, etc.

Alternatively, you can select a specific time frame like the third quarter of 2020. Additionally, CalSum allows you to export this data to Excel or Numbers, e.g., when you need a working time report for the last month.

Stop manually calculating your working time or fill in a spreadsheet every month – use CalSum, your little calendar extension.
