“What have I actually been spending my time on lately?”
Even if you use Google Calendar to manage your schedule, it can be surprisingly difficult to understand where your time actually goes.
By aggregating and analyzing your Google Calendar events, you can reflect on things like:
- Whether you are spending too much time working
- Whether your study time is increasing
- Whether you are making enough time for exercise or rest
Kotomil helps you aggregate, analyze, and visualize Google Calendar analytics with charts and reports.
For example, you can view:
- Time ratios by activity
- Total tracked time
- Average time
- Trends for specific activities
Google Calendar does include a “Time Insights” feature, but it has several limitations:
- Requires Google Workspace
- Mainly focused on meeting insights and Google Meet usage
- Primarily uses simple pie chart visualizations
Because of this, it is not always suitable for general schedule analysis, life logging, or personal time tracking.
Kotomil aggregates and analyzes your Google Calendar data to help visualize how you spend your time.
1. Analyze trends for specific activities
For example, if you record “Exercise” events in Google Calendar:

By connecting Google Calendar with Kotomil, you can analyze exercise trends over time using graphs and time analytics.

You can visually review things like:
- When you exercised
- How much time you spent exercising
- Whether you have been consistent recently
If you already record activities in Google Calendar, you can analyze many kinds of events and schedules.
Examples:
- Work
- Study
- Exercise
- Lessons or classes
- Meetings
- Focus work
- Hobbies
and more.
2. Analyze activity ratios for a selected period
Kotomil can also aggregate and analyze your Google Calendar events for a selected period, such as one week, to visualize time distribution ratios.

From this analysis, you can discover things like:
- Work takes up most of your schedule
- Exercise time is lower than study time
- Certain activities dominate your time usage
By analyzing your Google Calendar events, you can better understand your time usage patterns and daily habits.
Instead of using Google Calendar only for schedule management, Kotomil helps you turn your calendar data into time analytics to reflect on your routines, habits, and lifestyle.
