185 angry reviews in one category and the product brief writes itself, line by line

Of the ten categories in the review pull, co-parenting communication apps produced the largest complaint pile by a distance: 185 low star reviews. Themes, in order: price 96, crashes 53, privacy 42, sign in 30, accuracy 27.

What makes it unusual is that almost every complaint maps onto a rule the product chose, not a bug it has. Five of them, each one a quote:

Both parents are billed separately. "It was never clear that the two hundred plus fee has to be paid by each parent." In a category defined by two people who do not want to cooperate, requiring both of them to pay is remarkable.

The export is behind another payment. "Paid for the year, paid again for the PDF export of my own records, and I still have to pay monthly to use those PDFs." The entire point of the product is a record you can take to court.

The export is incomplete. "You cannot download all of the expenses, I had to build the list by hand to prepare for arbitration."

No calendar sync. "Does not connect to Google Calendar." A shared schedule that lives only inside the app.

Analysis that cannot be switched off. "The tone checker became permanent, everything I write is painted red, and there is no way to turn it off."

The brief is just those five inverted. One parent pays. Export is free, complete, and includes messages, expenses, calendar and call logs. Two way calendar sync. Monthly billing. Tone analysis optional.
