BestInterest is for divorced parents navigating a relationship after divorce or separation — especially if you're dealing with a narcissistic ex, parental alienation, gaslighting, or ongoing legal conflict. BestInterest use a proven communication framework that supports parallel parenting, JADE, BIFF, and Grey Rock to help you set boundaries, minimize conflict, and protect your child's well-being. Whether you're just starting the divorce process, managing ongoing legal abuse, or simply trying to find a more peaceful path — BestInterest will help you get there.
Co-parenting apps like OurFamilyWizard, TalkingParents, or AppClose rely on the threat of court reprimand to ensure good behavior, but this is often not enough when emotions run high. BestInterest is the modern solution for all co-parents navigating conflict. Reduce the conflict before court is even needed.

I wish I’d had this app years ago! The subscription seems pricy but I think I’ve saved more than double that in therapist fees in a few months just for the peace of mind that my ex’s messages are not only edited to be non confrontational but they’re on record should I need them in court one day. If you’re coparenting in any way other than 100% peacefully and respectfully you need this app.
Absolutely terrible and no support

Not only is the AI slow, it often times out. You can disable it but that’s their main feature they advertise, it’s not unusual for it to sit for a while “reviewing” a short reply. And of course if you say anything negative about th app it removes it. Documents shared are renamed to a jumble of numbers and you can’t preview them. There is no sound notification for messages. Trying to get email support is useless as they never answer.
We’ve made BestInterest smoother and more reliable across the app. This update improves subscription and support settings, message attachments and photo viewing, and report timestamps in your local time zone. It also includes fixes across sign-in and setup, family connections, expenses, calls, journal entries, and links that open in BestInterest.
