The Co-Parenting Calendar App Built for Two Households

Sharing a calendar between two households shouldn't feel like a project. DuetNest is a co-parenting calendar app where both parents see the same schedule, the same swaps, and the same handover notes — without arguing about who edited what.

Why a generic calendar app fails co-parents

A generic calendar app treats every event as equal. But co-parenting has structure: there's a base custody pattern, recurring events, one-off swaps, holiday overrides, child-specific activities, and a financial layer (who paid for camp, who owes for the doctor). When all of that lives in a shared Google calendar, everything gets messy. A dedicated co-parenting calendar app separates the base pattern from the day-to-day events, keeps an audit trail of changes, and connects the calendar to expenses and decisions — so a single dentist appointment lives next to its receipt and the agreement about who's paying.

Set up your shared family

Invite your co-parent by email. Both of you get equal access to the same calendar, expenses, and document vault.

Define your custody pattern

Pick a template (week-on/week-off, 2-2-3, custom) — the next 12 months are color-coded automatically.

Layer events on top

Doctor appointments, school events, soccer practice — add once, both parents see it, with the right child tagged.

Connect expenses and decisions

Tap an event to attach a receipt or open a decision (e.g., 'choose a pediatrician'). Calendar, money, and choices in one thread.

Purpose-built for two homes

Designed from day one for two parents, not for one user with reminders.

Lower-conflict by design

Structured fields and neutral language reduce the emotional charge of every interaction.

All the kid logistics in one place

Calendar, expenses, medical info, school documents, decisions — never tab-switch again.

Works on every device

Web, iOS, Android — install as a PWA, no app store needed.

Frequently asked questions

Is the co-parenting calendar app really free?

Yes. The shared calendar, custody templates, swaps, and Google sync are free forever. Premium plans add structured PDF exports and more storage.

Does it replace my personal calendar?

No — it complements it. Most parents keep their work calendar separate and use DuetNest specifically for shared parenting time.

Can grandparents and step-parents see it?

Yes. Invite extended family with read-only or limited-access roles, separate from the co-parent role.

What if we live in different countries?

DuetNest is time-zone aware and ships with 8 language packs and holiday calendars for the US, UK, Germany, Spain, Poland, Ukraine, Norway, Japan and China.
