Launching June 2026

The co-parenting app where neither parent is in charge.

ViviSync gives both parents equal, independent access — no admin parent, no gatekeeping, no requesting permission. Just family coordination that works the same way for both of you.

Millions of families are coordinating
across two households every day.

They're not in conflict. They're not looking for documentation tools. They just need a coordination system that works equally well for both parents — and nothing built for them yet.

Independent account · Same access

ViviSync is built on per-parent accounts. Both parents sign up independently. Both see the same schedule, tasks, and expenses — in real time. Neither can restrict, modify, or remove the other's access.

  • Independent billingEach parent subscribes to their own account. No shared login, no joint payment, no dependency on the other parent.
  • Real-time shared dataBoth parents see the same truth — the same calendar, expenses, and tasks — simultaneously, with no filtering or delay.
  • No hierarchyThere's no admin parent and no secondary parent. Equal Access isn't a setting — it's the foundation the whole system is built on.

Everything co-parents actually need.
Nothing they don't.

Built by co-parents, for co-parents. Every feature exists to reduce friction between households — not create it.

Task Management

Assign, track, and hand off tasks between households. Both parents know what's done, what's pending, and who's responsible — no text threads required.

All plans
Family Messaging

A dedicated in-app thread between co-parents. Everything in one place — separate from personal texts, separate from the noise.

All plans
Document Vault

Store insurance cards, medical records, emergency contacts, and school documents. Both parents can access them anytime, from any device.

All plans
Custody Calendar

A shared calendar for tracking your custody schedule — 7/7, 2-2-3, 3-4-4-3, and custom patterns. Both parents manage it together. No one controls it alone.

Custody plan
Expense Tracking

Log shared costs, split expenses, and keep records both parents can see. Receipts attached. Balances clear. No disputes about who paid what or when.

Custody plan
Smart Notifications

Morning briefings, handoff alerts, and task reminders — configurable by each parent independently. Stay on top of your family's schedule without the noise.
