I want to be fair to Cozi because I used it for over a year and it genuinely did what it said it would do. The shared calendar worked. The grocery list synced in real time. I could color-code by kid, which sounds trivial but actually helped when I was trying to scan a week at a glance. For the scheduling problem, Cozi is a solid app.
The thing is, the scheduling problem was never really my problem.
My problem was that I was carrying the whole household in my head and Marcus wasn't, and no amount of shared calendar was going to change who knew that Eli's allergy medication had to be refilled before the camping trip, or that the camping trip conflicted with the thing we'd said yes to four months ago and forgot about. The calendar showed events. It didn't show the awareness behind them.
I realized this in month eleven of using Cozi, when Marcus asked me if we were free the weekend of the 14th and I already knew we weren't because I had been tracking three things converging on that weekend for six weeks. He hadn't thought about it once. The calendar was right there. He had access to it. He just didn't carry the map.
That's not a Cozi failure. That's a different problem entirely.
Cozi was built for a specific user: a person who is already managing the household and wants a better system to stay organized. It's genuinely good at that. The shopping list, the calendar, the family journal — all of it assumes one person is running things and gives them better tools.
What it doesn't do is ask the question of whether one person should be running things.
That question is actually harder to build for, and I think it's why most household apps don't try. It requires the app to have an opinion about task ownership, not just task visibility. It requires a way to assign something to someone and have that person carry it forward without the assignor being the tracker. That's different from sharing a calendar.
Orbyt starts from that question. The mental load split between two adults is the problem it was built for. It's rougher around the edges — it's newer and in beta and Cozi has a decade of polish that Orbyt doesn't have yet. But when I open Orbyt, I'm working on the right problem. When I open Cozi, I'm better organized but still carrying everything myself.
So honestly: if your main issue is household scheduling chaos and you want a clean shared calendar with grocery lists and meal planning, Cozi is fine. It's free, it works, it's been around long enough that they've sorted out the annoying bugs.
If your issue is that one person in your household carries the mental map and the other one doesn't, Cozi isn't going to fix that. That's what I'm using Orbyt for. Still in beta at orbythq.com, but worth a look.
