The Plan screen in the app, last confirmed on September 21: week on, week off, every Thursday at 15:30. From September 21, changeover at the school gate, Autumn holidays October 5 to 17, with you. The other household picks first this year, in 2027 you do.
The plan, on your phone
The “Where you sleep” view of a child with an account of its own: Monday to Wednesday with Dad, Thursday with Mum. Friday to Sunday, October 2 to 4: where you sleep is not settled yet. Hanna might not be with you on those days. Your parents are still working that out; you’ll know by Sunday, September 27. There’s nothing you need to do. This is what was agreed: One week with Dad, then one week with Mum. Thursdays at 15:30 Dad and Mum take turns picking you up at the school gate. Below, “Your school: Timetable and tests”.
“Where you sleep”: the same plan for Timo

How it goes today

  1. “Can you have Timo this weekend?” Two days of nothing, then three question marks.
  2. “Who has the kids on Thursday?” The answer is somewhere in a chat from March.
  3. The test was on Tuesday. You hear about it on Wednesday.

What’s missing isn’t another chat. It’s one state that holds in both homes, and a rule for when nobody replies.

What CoParity does

Six areas, one state. Everything here looks the same on both sides.

Every feature in detail

A week with CoParity

The week of September 28 to October 4, as it stands with you and with Sabine. Sabine has asked about three days. Tap an answer.

Sabine asksAnswer by Sunday, September 27

October 2 to 4: Timo would be with you instead of with Sabine. Hanna would stay with Sabine.

Without an answer the plan stands.

The question has a reply-by date

Sabine asks on Friday, more than 48 hours before the first day. You can answer until Sunday, September 27. You don’t have to: without an answer the plan stands.

The test sits with both of you

Thursday’s study session and Friday’s test are in the plan and in both calendars, even though Timo is with Sabine then. Whatever you answer, the dates stay the same.

The changeover stays as it is

Thursday, 15:30, at the school gate. Running late one day? You give the new time (“Give a time”). Nothing to reply to.

For the kids

With an account of his own, Timo sees “Where you sleep”: “Tonight you’re with Dad.”, the next days and “Your school”, read-only. When something is still being worked out, he reads: “There’s nothing you need to do.”

Hanna has no account. For her, you open “Hanna’s view” in Settings and hand her your phone: the sentence of the day, a timeline and “Emergency 112”. A child gets an account only when both of you agree.

More about the child’s view

The Settings of the app: language, appearance, “Who sees what”, “Open Hanna’s view: The view for Hanna, in their words. You can hand them the phone.” If something happens: Timo, Hanna. “Who may collect”, “Documents”, “Notifications”.

What you can count on

  • Both of you see the same.

    Plan, questions and school: one state for both homes. “Who sees what” lists what each person sees.

  • One purchase for the whole family.

    Nobody sees who paid, and whoever pays sees no more than the other household.

  • Servers in Germany.

    Run by Datargo GmbH in Frankfurt am Main. Report cards and documents are encrypted. No ads, no tracking.

The “Who sees what” screen in the app: Everyone in this family sees a different app. Here is who sees what, and you can check it yourself. Martin Berger (you): This is your own view. Sabine Breuer: Sees everything, same as you, with “See this screen”. Below, Gustav Klempt, who looks after Timo and Hanna, with what he sees.

Questions

Isn’t WhatsApp enough?

For writing, yes. What it lacks is a state that holds and a rule for when nobody replies. In CoParity every change has a reply-by date, with no reply the plan stands, and the result is in both calendars.

And if the other household isn’t on board yet?

Then you start on your own. You enter the plan, you see it and the dates are in your calendar. Whoever joins later by invitation sees the same plan.

The other household uses Android. Does that work?

Not quite yet. The Android app is to follow on Google Play; there is no date yet. Today an account is created only in the app on the iPhone, and that is also where the invitation is accepted. Until then you start on your own: the plan sits in your calendar, and with the family unlock you pass it on as a sheet (PDF).

What does CoParity cost?

The plan, questions, notices, calendar, school holidays, the child’s view, who may collect, the emergency number and health notes cost nothing. The family unlock (the “CoParity Familie” subscription) for the timetable and tests, report cards, the sheet and importing events is €4.99 a month or €49.00 a year, renews automatically and can be cancelled at the end of the current period. One purchase covers the whole family.

Who sees what I enter?

The plan, the questions, the notices and the school are seen by both of you, the parents in the same family. Carers and grandparents see only their part, a child only its own. Whatever else is in your calendar stays there.

Are there read receipts?

No. Nobody sees when you read something. A question has a reply-by date, and until then you reply or you don’t.

Do the school holidays come into the plan by themselves?

You choose the German state, and the holidays are ready to bring in, for all 16 states. For each of the holidays you choose “with me”, “at the other home” or “half and half”. Who chooses first alternates every year. This costs nothing.

Can the kids use the app?

With an account of its own, a child sees “Where you sleep” and “Your school”, read-only. An account exists only when both of you agree. For a child without an account, you open its view in Settings and hand it your phone.

Where is the data kept?

On servers in Frankfurt am Main, run by Datargo GmbH. Report cards and documents are encrypted. There are no ads and no tracking.

What can I do in the browser?

At app.coparity.de you sign in with the account from the app. There you read the plan, answer open questions, keep the timetable, tests and study sessions on a laptop and print the timetable. Account, invitation, confirming the plan and new changes work in the app.

More answers in the help pages

You can start on your own.

The plan sits in your calendar even if the other household only joins later. Whoever joins by invitation sees the same plan.
