Every feature

What CoParity does, area by area. Everything here is built and runs against the same state for both homes.

The care plan

  • A rhythm of alternating weeks: week on, week off, 2-2-3 and other patterns.
  • Changeover days with time and place, for example Thursday, 15:30, at the school gate.
  • Holidays and exceptions as periods, with the rule of who chooses first in which year.
  • Bring in the school holidays of your German state, all 16 of them, and choose “with me”, “at the other home” or “half and half” for each break.
  • Both parents confirm the plan. Until then it shows as entered, after that as agreed.
  • Start on your own: the plan holds for you, and Sabine joins by invitation.
The “Enter a plan” form in the app: Where is the child first? Changeovers, with “Add a changeover”. Holidays and exceptions, with “Add a period” and “Add school holidays”. Holidays: who picks first? After that it alternates every year on its own.
The School holidays form in the app: state Hessen. Autumn holidays October 5 to 17, with me. Christmas holidays December 23 to January 12 2027, with the other household. Easter holidays March 22 to April 2 2027, with me. Summer holidays June 28 to August 6 2027, with the other household. At the top, “Cancel” and “Add”.

Changes

  • You propose a change as a question with a reply-by date, for example to Sabine: “October 2 to 4: Timo would be with you.”
  • A question needs at least 48 hours’ notice; the app sets the reply-by time. For something short-notice on the same day there is “Give a time”.
  • The answer is “Fine by me” or “Does not work”. No reason needed for a no.
  • Without an answer by the date, the plan stands.
  • “Give a time”: a different time for one changeover on the same day, the reason optional. Sabine gets a notification; in the app it is gone at the end of the day, your calendar keeps the time you gave.
  • The other household sees it right in the plan: “Sabine gave notice of 17:20.” There is nothing to reply to.
  • Push notifications if you want them. A notification never names a person, a day or a content.
The “Once different” form in the app: From 4 Oct 2026 15:00 until 5 Oct 2026 15:00. A one-off change applies only to this period. The plan stays unchanged. Where would the child be instead? With me or with the other household. At the top, “Propose”.
The Plan screen in the app, section “Once different”: October 2 to 4. Then Timo would be with you instead of with Sabine. Hanna would stay with Sabine. Answer by September 27. Buttons “Fine by me” and “Does not work”, below them “Without an answer the plan stands.” Further down the appointments with the maths study sessions and the maths and English tests.
The “Give a time” screen in the app: Which changeover? Thursday 15:30. Time on the same day. Sabine gets a notification about it. In the app it is gone at the end of the day; your calendar keeps the time you gave. Reason, optional: none, on the way, work, appointment, other reason.
The Plan screen in the app with a notice: By the plan: changeover Thursday 15:30. Sabine gave notice of 17:20. Reason: work. Below, under “Once different”, the question about October 2 to 4.

School

  • School, class and state for each child.
  • A timetable for each term with subject colours, editable; lesson times carry over from the previous term.
  • Tests and study sessions as the child’s appointments, visible in both homes and in the calendar.
  • Report cards as encrypted scans, with a release of its own for each parent. Every parent of the family sees them, the child does not; the app reads nothing from them.
  • A print view of the timetable in the browser.

More about school

The School screen in the app: Timo, Goetheschule, class 4b, Hessen. Timetable for the first half-year, Monday to Friday in subject colours: maths, German, English, PE, science, music. Below, “Edit timetable”.
The School screen in the app, tests and study sessions: maths study session on Saturday, September 26, 15:00, and on Monday, September 28, 16:00, for the maths test on September 30. Maths test, fractions, on Wednesday, September 30. English test on Friday, October 2. “Add a test”, “Add a study session”. Every parent of this family sees it, in the calendar too.

Calendar

  • The plan writes itself into your own calendar: directly on the iPhone, or as a subscription for Outlook, Google and other devices.
  • The children’s appointments (doctor, sports, tests) sit in the plan and in the calendar; where needed, with Sabine’s agreement.
  • Bring in events from your own calendar (family unlock).
  • Unless you choose otherwise, no appointment titles and no places appear in the calendar.
The Calendar screen in the app: Where do you plan? In a calendar on this iPhone, recommended when your calendar account lives on this device. Or in Outlook or on another device, through a subscription address that keeps itself up to date.

The kids

  • A child with an account of its own sees “Where you sleep”: the sentence for tonight, the next days in blocks, “This is what was agreed” and “Your school” with timetable and tests, read-only.
  • When something is still being worked out, it reads “where you sleep is not settled yet” and “There’s nothing you need to do.” The negotiation itself the child does not see.
  • For a child without an account, you open its view in Settings on your phone: the sentence of the day, a timeline and “Emergency 112”.
  • A child gets an account only when both parents agree, with a text the child can read itself.
  • No grades, no counting. What a child sees, you both see just the same.

More about the child’s view

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”.
The school page of a child with an account of its own: Goetheschule, class 4b, Hessen. Today: 08:00 maths, 09:55 German, 10:45 music. Your week as a timetable in subject colours, Thursday marked. Tests: maths, fractions, on Wednesday, September 30, with time to study on September 26 and 28.

Everyday and safety

  • “Who may collect”: the people who may pick up a child, with a pick-up sheet for school and after-school care.
  • The sheet: the plan as a PDF for school, after-school care and grandparents, with the family unlock.
  • Documents, shared encrypted.
  • “If something happens” for each child: allergies, medication, the emergency number.
  • Widgets and a Live Activity on the iPhone on changeover day.
  • “Who sees what”: everyone in this family sees a different app. It lists what each person sees, carers and grandparents included.
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”.
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.
The Sheet screen in the app: the sheet for the plan, with the buttons “Done” and “Share”.

The Android column shows the finished app that is to follow on Google Play; there is no date yet. A purchase on the iPhone covers the whole family, on every device.

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.
