BestInterest review
A broad co-parenting toolkit with AI assistance and a useful free tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
BestInterest is a co-parenting app for separated parents, including families managing high-conflict communication. It brings secure messaging, AI-assisted message review and coaching, shared custody scheduling, expense tracking, payments and reimbursements, calls, journaling, document storage, and exportable records into one service. Solo Mode and Boundary Line also support one-parent use when the other parent does not participate. The app is available on web, iOS, and Android, making it suitable for parents who need a shared record of communication, schedules, expenses, and custody-related documents.
The permanent Free plan covers secure messaging, a shared calendar, expense tracking, AI co-parent coaching, and CSV data exports. Connect costs $9.99 per month or $99.99 per year and adds audio and video calls, photo uploads, secure document exchange, verified court reports, and shared scheduling. Protect costs $14.99 per month or $149.99 per year, adding Message Shield, Tone Guardian, Smart Silence, Parenting Plan Analysis, and unlimited verified reports. Protect Plus costs $29.99 per month or $299.99 per year and adds unlimited calling, Boundary Line Plus, voicemail, call recording, and call transcription. A 14-day free trial is also available.
Its strongest distinction is breadth: BestInterest combines communication safeguards, scheduling, child-related finances, calling, storage, and reporting rather than focusing on a single co-parenting task. The AI features are directed at message filtering, outgoing-message review, and coaching, while verified PDF reports and CSV exports support record keeping. Parents who need an all-in-one app with a free entry point should find the feature structure appealing. Those seeking third-party integrations, or who only need a basic calendar and messaging tool, may prefer a narrower alternative; several of BestInterest's more specialized capabilities require higher paid tiers.
