Perhaps try looking at a combination of TickTick and Apple Calendar app (if you are on Apple). I have a couple of different calendars within Apple - home, work and Toastmasters (but could be family). Within TickTick, you can add in tasks to appear on the calendar so your tasks can be moved around your appointments. You can set up repeating/recurring tasks. Also, consider using Getting Things Done (GTD) methodology- gets everything out of the brain so it can be used for thinking. The TickTick free app is awful - premium is MILES better.
