BeNice and Harmoneaz are both Dutch apps for separated parents, with data stored in the EU. They have a different focus. BeNice is mainly about the tone of communication, with help from AI. Harmoneaz is about the practical side: schedule, handovers, agreements, child support and expenses.
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 BeNice does better.
This page is written for parents living in the Netherlands. Prices are those in the Dutch App Store and Google Play.
The short answer
- Choose BeNice if communication is difficult and you want help from an AI coach that makes messages calmer and takes the blame out of what you receive. Also if the other parent does not want an app and prefers to reply by e-mail, or if you want a photo album and child details.
- Choose Harmoneaz if you want the practical side well organised: child support with the annual indexation, a packing list for every handover, tasks, and agreements you record from a message with one tap. Also if children, a new partner or grandparents need to follow along, or if you would rather not send text to an AI service.

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

- 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.
