I use Google Calendar - both the web site and the phone app. We have separate calendars for me, DH, the kids, and our dinner menu. Google Calendar lets you give each one a different colour and toggle them on or off. Most of the time I keep them all on, but sometimes I just want to see my own, so I toggle off all of the others.
Our schedule, even when busy, is pretty much the same week to week. Hubby doesn't have to keep track of much because I'm the one hauling kids around and having meetings outside of work.
I keep track of my things in a bullet journal.
