The short answer
Cozi is a family organiser, built for parents keeping track of their children’s schedules. Casamates is built for adults who share a home. The biggest difference is money: Cozi has no way to track or split shared costs, while Casamates lets you split bills, see who owes whom and settle up, free and unlimited. Cozi’s free plan also only lets you see and add events in the next 30 days and shows ads; the full calendar needs Cozi Gold at $39 a year. On Casamates, the shared calendar, recurring chores and shopping lists are free, with no ads.

Questions people ask
Is there a Cozi alternative for flatmates?
Yes. Casamates is built for people who share a home rather than for families. It has a shared calendar, recurring chores and shopping lists like Cozi, and adds what flatmates need most: splitting bills, tracking who owes whom and settling up, all free with no ads.
Does Cozi split bills?
No. Cozi has a calendar, lists, to-dos, chores and recipes, but no expense tracking or bill splitting. Households that share costs need a separate app, or an all-in-one app like Casamates that does both.
Is Cozi free?
Cozi has a free plan, but it only lets you see and add calendar events in the next 30 days, and it shows ads. Cozi Gold ($39 a year) removes the limit and the ads, and Cozi Max ($79 a year) adds AI features. Casamates is free to download, with no ads and no 30-day window on the calendar.
Can flatmates use Cozi?
They can, but it is designed around one family account. Everyone shares a single password, anyone can edit or delete anything, and removing someone means resetting the password for everyone else. There is also no way to split bills. Casamates gives each flatmate their own account and is built around shared costs as well as shared plans.
