How about to-do items?
TimePage appears to use its own database, and does not touch OS X Calendar or Reminders data at all, so I don't see how it could hurt either.Usually I just use Calendars and Timepage. I worry that using too many calendar apps may mess up the real schedule due to potential compatibility issue. Do I have to worry?
I think the app requires one to enter the start and end time.
Which can be the exact same time. Are you just wanting to set up a daily to-do list or some generalized list?
Set it up as an 8:00 am start/end each day and list all the stuff you need in notes very easy
