The TalkingParents free plan attracted a specific group: parents who needed basic co-parenting structure but not a full documented communication suite.
Many of those parents used the shared calendar to keep track of the custody schedule. Not because they needed court-admissible records, but because having one place where both parents could see the schedule reduced confusion. The messaging was occasional and informal — reminders about pickups, notes about schedule changes.
For that use case, the free plan made sense. A custody schedule and a basic communication layer, at no cost.
With the free tier gone, the question is: which part actually mattered?
If the scheduling was the main thing
CustodyBuilder handles this for free. It builds the custody schedule, calculates overnights and parenting time percentages, and produces a PDF you can share. No account required, no subscription.
If the documented messaging was the main thing
There's no free alternative that does this well. TalkingParents, OurFamilyWizard, and AppClose all charge because the infrastructure for timestamped, stored communication with court-ready export isn't cheap to run. If you genuinely need that, the cost is real and the alternatives are paid.
If it was both
You may need two tools — CustodyBuilder for the scheduling piece, and a paid app for communication. Or you may find, on reflection, that your communication works fine over text or email and the messaging feature wasn't doing much work.
