Duonique
Your own co-parenting app, just for you

Two homes,
one anchor.

Duonique is your personal app as a separated parent: your custody schedule and your own record of everything around the children, kept for yourself and not shared with the other parent. Always know when the children are with you, keep what matters, and stay close while they’re at their other home.

Coming soon for iPhone and Android

What is Duonique?

One personal app for your custody schedule, your own record and staying close.

Your schedule at a glance

Draw your week or answer a few questions. You see straight away when the children are with you, with special days and changes added in.

Your own record

Note for yourself what happens around the children: appointments, costs, what was agreed, a handover that changed. With a date, a note and attachments, easy to find by child and by month.

Staying close

On the days the children are at their other home, have a few messages ready and get a gentle nudge at a good moment. You send them yourself, through WhatsApp.

How it works

Your custody schedule, clear in three simple steps.

  1. Set up your schedule

    Week on, week off, every other weekend, even or odd weeks, every Wednesday: Duonique works it out for you.

  2. Note your moments

    In a few taps: choose who it's for and what kind of moment it is, and add a photo or document if you like.

  3. Share only what you want

    Turn a moment into a tidy PDF, for yourself or for whoever you choose.

Just for you

Your own app, not a shared one.

Duonique isn’t something you use together with the other parent: there’s no shared calendar and no chat. It’s your personal app. The other parent sees nothing, and nothing is shared unless you share a moment yourself. Your data is stored on a server in the EU.

  • Lock it with Face ID or your passcode, if you like
  • No shared calendar or chat with the other parent
  • Shared only when you choose to
Your own record

Keep what matters, for yourself.

A trip to the dentist, a parents’ evening, the cost of a school trip, what was agreed for the holidays or that first swimming badge: keep it for yourself, with a date, a note and attachments, neatly by month. Bit by bit, you build your own record, without involving the other parent. It’s there whenever you need it, and you can share a moment as a PDF if you want to.

  • Health
  • School
  • Appointment
  • Costs
  • Communication
Messages and reminders

Close by, even when the children are at their other home.

Have a few messages ready to ask how the children are. While they’re with the other parent, Duonique gives you a gentle nudge now and then, at a calm time of day. You send the message yourself, through WhatsApp: the app never sends anything for you.

Questions about Duonique, your personal co-parenting app

How is Duonique different from other co-parenting apps?

Most co-parenting apps are shared: both parents use the same calendar and message each other in the app. Duonique works the other way round. It’s your personal app, just for you: your schedule and your own record of everything around the children and parenting. The other parent doesn’t use it with you and sees nothing, unless you share a moment yourself.

How do I make a custody schedule or parenting calendar?

Draw your week in the app or answer a few questions, and Duonique works out the calendar for you: week on, week off, every other weekend, even or odd weeks, every Wednesday or the first weekend of the month. It works for a 50/50 split and any other rhythm, with one child or several.

Does it work with a parenting plan or child arrangements order?

You enter the rhythm you follow yourself, whatever it is based on, and Duonique shows it in your calendar. The app doesn’t read or check any documents, and it doesn’t give legal advice.

Can I adjust holidays, birthdays and changes?

Yes. For holidays, birthdays and other special days you choose where the children are, also every other year. A trip, a swap or coming a day earlier is added as a change, once or repeating.

Does it work with more than one child or schedule?

Yes. Children can share a schedule or each have their own, every schedule in its own colour, and the calendar shows them all together.

What can I keep in my own record?

Anything around the children and parenting you want to keep for yourself: appointments, costs, school, health, what was agreed. Each moment has a date, the child or children, a type and, if you like, a note, an amount, photos or documents. It’s all grouped by month and by child, there for whenever you need it. Any moment can become a PDF that you share with whoever you choose.

Can the other parent see what I write?

No. Duonique is your personal app: the other parent sees nothing, and nothing is shared unless you share a moment yourself. Your data is stored on a server in the EU. You can also lock the app, your moments and your messages with Face ID or your passcode.

Does Duonique send messages to the other parent?

No. Duonique doesn’t send anything itself and has no chat. You can have a few messages ready to ask how the children are. While they’re at their other home, you get a gentle nudge now and then during the day, and you send a message yourself through WhatsApp, if you want to.

When will Duonique be available, and is it free?

Soon, for iPhone and Android, and the first version is free. As soon as the app is in the App Store and on Google Play, you’ll find the links here. It speaks English, Dutch, French, German and Spanish.
