Introducing a new partner to your children and your co-parent
“Dad has a girlfriend. Did you know?” It’s Sunday evening. Your son drops his bag in the hallway, kicks off his shoes and says…
New: a completely new look
Care schedule, handovers, agreements, costs and discussions in one app for both parents. So you can stop searching through texts, emails and loose notes.
Free for 14 days. For iPhone, iPad and Android.
The calendar shows who has care on each day. A swap or a holiday week is recorded as a temporary change; your regular schedule stays in place underneath. The dentist, swimming lessons and the parents’ evening are there for both parents at the same time.

Every handover shows what needs to come along and what the other parent should know: the packing list, the notes from the past days and what is coming up next.

Put the agreements from your parenting plan in the app, so they do not disappear into a drawer. Child support is tracked there too; for the Netherlands the app can apply the yearly indexation.

Add an expense with its receipt and Harmoneaz keeps track of how costs are split and what still needs settling. You make the payment yourselves; the app does not move money.

School, holidays, the new bike: each topic gets its own conversation, with a photo or PDF attached when that helps. Sent messages cannot be edited or deleted. That keeps it a reliable record of what was discussed, for both of you.

A calmer design, four fixed places at the bottom and a new part: Discussions. See it in thirty seconds.
I am a co-parent myself. Scattered notes, re-aligning agreements every single time, tracking and calculating child support by hand, forgetting to pack things — I ran into all of it. That is why we built Harmoneaz: all the admin for the kids in one place, available to both parents right away.
One subscription per parent. Without one, the other parent can follow along and reply in Discussions.
The first 14 days are free. The subscription is per parent and runs through the App Store or Google Play.
Cancel any month.
Works out at less than € 3 a month.
Yes. Every part works when you start on your own. Only Discussions needs the other parent.
No. The subscription is per parent. Without one, the other parent can view everything, check off the packing list and reply in Discussions; adding or changing things takes their own subscription. Read: what does Harmoneaz cost?
Only the people you have invited to your group yourselves. Nothing is public and there are no ads.
On servers in the EU. There is no advertising or tracking code in the app. Read: how we protect your data
No, and that is on purpose. A sent message stays as it is, so the conversation remains the same for both parents. You can archive a topic once it is settled.
“Dad has a girlfriend. Did you know?” It’s Sunday evening. Your son drops his bag in the hallway, kicks off his shoes and says…
“Mom, when am I at Dad’s again?” It’s Wednesday evening and your daughter is sitting at the kitchen table with her drawing. She looks…
“Did you get that letter from school too?” It’s Tuesday evening and you get a text: “Did you get that letter from school too,…
