OurFamilyWizard (OFW) is an American app, widely used in court cases in the United States and the United Kingdom. Harmoneaz is a Dutch app, in English and Dutch, built for parents living in the Netherlands, including expats. Below they are compared feature by feature.
We make Harmoneaz, so we are not impartial. That is why every claim has its source at the bottom of the page, and why we also say where OurFamilyWizard does better.
Prices are those in the Dutch App Store and Google Play.
The short answer

Strengths and weaknesses
Harmoneaz
Who it suits: Parents in the Netherlands who want the practical side well organised: schedule, agreements, child support and expenses.

- Start an expense with a photo or PDF of the receipt: the app reads it on your own device, without AI, and fills in the amount, date and shop.
- When the other parent changes something in the calendar, a task or the custody schedule, you get a notification and see it straight away, without refreshing.
