Right now I can't make use of it as it doesn't include or specify any sub-calendars (personal, work, etc.) in your Google account. Therefore people can book timetables even if your calndar is showing that you are busy.

I see this program as something I will look into in a couple of months or a year and see how it has been progressing. It has been released some months too early. Unfortunately I skipped another deal for this as I did hope for a lightweigth scheduler. But I keep my fingers crossed and hope it will further develop (but if if zoom.ai or meetfox will pop up again...).
