Cozi vs Larkling (2026): Free Calendar vs Free Co-Parenting App

Cozi is a handy free family calendar. But for separated co-parents it’s missing the two things that matter: a full shared schedule and a reliable record. Compare.

Cozi vs Larkling in 2026: Cozi costs Free (with ads) / ~£30/yr Cozi Gold and does one or two things well. Larkling is free forever and covers the core co-parenting job — plus AI tone coaching, Solo Mode and all-family support.

🐦 The short version: Cozi is a decent option if you’re happy to pay. Larkling already does the thing that matters — a reliable, de-escalated co-parenting record — for free, no credit card, and it keeps working when your co-parent won’t join.

The Honest Trade-Off

To be fair to Cozi, Cozi is genuinely free and good for one-household family organisation — shopping lists, chore lists, a shared calendar. The catch: its free tier only shows the next 30 days (too little for co-parents planning ahead), and it has no non-editable messaging or record for family proceedings.

None of that solves the problem Larkling was built around: a genuinely free, reliable co-parenting record that works for every kind of family — even when only one parent engages.
