The case
BestInterest is the 2026 answer to a U.S. problem the incumbents ignore: the other parent refuses the app. Boundary Line can still reach them. AI filtering of incoming hostility is the product. Newer, less court-famous than OFW.
U.S. high-conflict co-parenting. Free tier still exists, unlike TalkingParents and AppClose.
