I only like to meet in the afternoons. Can I set more advanced preferences like that for flexible meetings?

Yes. You can customize a number of preferences about your schedule under Ideal Day within the Clockwise app. For example, if you prefer meetings in the afternoons, we recommend you set your Focus Time for in the mornings.

If you'd like to make a specific meeting Flexible during certain days/times of the week, you can edit these preferences within the event itself via the Clockwise Calendar or by clicking the event itself within your calendaring app. You can slide the hours you would like the meeting to flex between per event.
