A Common Ground Studio product

Nobody should have to ask how the week went.

CoCoparent keeps one shared record of a child’s days across two homes — what they ate, how they slept, what made them laugh, what’s in the bag going back. So the handoff has already happened before anyone opens a text thread.

What it’s for

A coherent celebration and record of time away.

When a child moves between two houses, the week they just had moves with them — and right now it moves by text message. One parent asks, the other answers, and both of them feel something they didn’t intend: one feels like an interrogator, the other like they’re being audited.

A record that is simply there defuses all of that. Nobody has to ask, because nobody has to be told.

The handoff packet

Four things that are really one thing.

What came back in the bag, what happened while they were away, when they move next, and what the other house needs to know before the door opens. Apart, those are features. Together, they’re the handover — and the handover is the product.

What came back in the bag

Packed at one house, checked off at the other. The gray hoodie stops being an argument and becomes a note.

What happened while they were away

Meals, sleep, moods, medicine, the small enormous firsts. Logged in a tap, read in a glance.

When they move next

Both houses see the same changeover time, and neither can move a child without the other agreeing to it.

What the other house needs to know

The things you only look up when you urgently need them. Written down once, in the place both parents already have open.

The schedule

Whose day it is, without asking.

Set the pattern once — every other week, 2–2–3, alternating weekends, or something only your family does — and the months draw themselves. Each parent picks the color they read as theirs.

Change the rule and you see exactly which days move before you commit to it. The other parent has to agree before a child actually changes hands.

Where the line is

Built for households that want to work together.

Plenty of good software exists for co-parenting that has gone to court. This isn’t that, and trying to be both would make it worse at each. CoCoparent assumes two people who want the same child to have a good week.

No message thread

There’s nothing here to print out and hand to a lawyer, and nothing scoring your tone. You already have a phone for talking to each other.

No expense ledger

Splitting the cost of soccer cleats is a real problem. It is not this one, and bolting it on would turn a keepsake into an invoice.

No audience

Two parents, and anyone they choose to add — a grandparent, a nanny, the other household. No feed, no followers, nothing public.

Privacy

A child’s week is nobody else’s business.

This is the most personal category of data there is — a real child, named, with their meals and their medicine and their bad nights in it. It is treated that way.

Only your family sees it

Access is enforced on the server, family by family, not merely hidden in the app. No other family can reach your records, and neither can we in the ordinary course of running it.

Never sold, never advertised against

There is no ad network, no data broker, and no analytics profile built from your child’s day. The subscription is the business model.

Yours to take back

Export the whole record whenever you want it. Close the account and the data goes with it — permanently, not archived somewhere for later.

A year of a child’s days is not something you export to a text thread.

CoCoparent is on the App Store and Google Play. Invite your co-parent with a code and you are both writing into the same record.
